Cambridge Audio's pretty, petite amp packs a powerful punch
Quick Summary
At just 21.5cm wide, Cambridge Audio's new MXW70 power amp is made small, but it delivers big audio.
The amp is spec'ed to provide up to 125W of power in stereo, 250W in mono.
To paraphrase Douglas Adams, power amplifiers are big. You won't believe how vastly, hugely, mind-bogglingly big they are. But Cambridge Audio begs to differ.
Its new MXW70 power amp delivers a lot of power from an extremely small footprint.
The MXW70 has been designed to sit with the equally compact MXN10 Music Streamer to make a complete Hi-Fi stack, although you can of course use it with whatever audio source you wish.
It puts out 70W to 125W per channel in stereo mode, and it's bridgeable in mono mode to deliver 250W.
T3 reviewed the Cambridge Audio MXN10 streamer some time ago and really loved it: we gave it the full five stars and praised its "deeply enjoyable" performance. This new amp looks like it's the perfect partner.
The chassis is just 215mm wide by 215mm deep and 57mm high, and it's all-metal with a minimalist design and Cambridge Audio's familiar Lunar Grey finish.
It's even more minimalist than the music streamer, in fact. That has a Wi-Fi indicator and four buttons in addition to its power switch, while the MXW70 has a power button and little else.
The amplification is Hypex NCORE Class D which, according to Hypex, delivers "the ultimate in clarity, resolution and musicality". The MXW70 also comes with premium XLR inputs as well as the obligatory stereo RCA. There's a 12V trigger with pass-through too.
Frequency response is 10Hz to 30kHz (-1dB) and power output is 2 x 70W to 8 ohms stereo, 2 x 125W to 4 ohms stereo, and 250W to 8 ohms in mono mode.
The Cambridge Audio MWX70 will be available this summer from the firm's website and the usual approved retailers. Its recommended selling price is £499 / €599 / $599 (about AU$1,033).

Ripple: Banks Have Invested Over $100 Billion in Blockchain Infrastructure Since 2020
Traditional banks have invested more than $100 billion in blockchain since 2020, according to a recent Ripple-backed report claiming digital assets are going mainstream. That figure comes from 'Banking on Digital Assets,' a joint study by Ripple, CB Insights and the UK Centre for Blockchain Technologies (UK CBT), which analyzed more than 10,000 blockchain deals and surveyed over 1,800 global finance leaders. According to the findings, major banks are ramping up investments in custody, tokenization, and payment infrastructure — despite regulatory uncertainty and market volatility. The report estimates that more than $100 billion has been invested in blockchain and digital asset initiatives globally between 2020 and 2024. It also found that 90% of surveyed finance leaders believe these technologies will have a significant or massive impact on finance within the next three years. From 2020 through 2024, traditional financial institutions participated in 345 blockchain deals globally, the report says. Payment-related infrastructure drew the largest share, followed by crypto custody, tokenization and on-chain foreign exchange. Roughly 25% of investments focused on infrastructure providers powering blockchain settlement and asset issuance rails. More than 90% of finance executives surveyed by Ripple believe blockchain and digital assets will have either a 'significant' or 'massive' impact on finance by 2028. Among bank respondents, 65% said they are actively exploring digital asset custody, with more than half citing stablecoins and tokenized real-world assets as top priorities. Examples cited include HSBC's tokenized gold platform, Goldman Sachs' blockchain settlement tool GS DAP, and SBI's work on quantum-resistant digital currency. Still, most respondents say consumer-facing digital assets are not the immediate focus — less than 20% of banks reported offering crypto trading or retail wallets. The report frames the shift as more infrastructural than speculative. Institutions are largely investing in blockchain to modernize cross-border payments, streamline balance sheet management, and reduce reliance on legacy rails. Ripple, which provides enterprise-grade blockchain solutions for banks, positioned the findings as evidence that 'real-world asset tokenization is entering the implementation phase.' Even as regulatory clarity lags in many jurisdictions, more than two-thirds of surveyed banks say they expect to launch a digital asset initiative within the next three years. Those efforts may range from piloting tokenized bonds to building interoperable settlement layers for CBDCs and private stablecoins. Despite recent setbacks in crypto markets, Ripple's report argues that capital formation is accelerating, not retreating. It notes that blockchain investment from traditional finance hit a post-FTX high in Q1 2024, and that emerging markets — including the UAE, India and Singapore—are driving adoption faster than the U.S. and Europe. For blockchain firms and infrastructure providers, the message is clear: the next wave of institutional adoption won't hinge on hype cycles or retail mania, but on quietly transforming the pipes of global finance.

Lamborghini Temerario test drive: $380K hybrid supercar delivers mind-boggling performance
Lamborghini's (VWAGY) latest creation, the Temerario supercar, has some big shoes to fill. Let me rephrase that — the 900hp, all-wheel drive, plug-in hybrid Temerario with a 10,000 RPM turbo V8 has some big shoes to fill. Che cosa? That's because it's replacing the much-loved Huracán: the outgoing serpent-like, alien-looking creation equipped with a sublime, yet ferocious when needed, naturally aspirated V-10 engine. The Huracán was amazing. But times are changing. Around a year ago at Monterey Car Week, Lamborghini unveiled the Temerario, which loosely translates to 'reckless' in Italian. The long-in-the-tooth Huracán — which, believe it or not, is over 10 years old and shared some underpinnings with sister brand Audi's R8 — needed a refresh. Lamborghini also sold 30,000 units of the $250K+ Huracán, its best-selling car ever. In other words, it couldn't mess this up. And with changing rules like emissions and electrified propulsion needed in certain European locales, hybrid power was needed. Lamborghini knew it had to convince buyers this wasn't a 'green' thing — it's about performance. It did this convincingly with the Revuelto, its range-topping supercar that combines a V12 with a hybrid system, using electric motors more for performance than range. Switch Auto Insurance and Save Today! Affordable Auto Insurance, Customized for You The Insurance Savings You Expect Great Rates and Award-Winning Service Lamborghini's CEO Stephan Winkelmann notes the car is completely new from top to bottom, including, of course, the new powertrain. It has to be exciting, he says, but also livable. Lamborghini seems to have threaded that needle, at least for now: The car is sold out through its first year of production, he said, which is a nice start for the brand. The drive I took the Temerario on the track for a few sessions to put the car through its performance envelope. Styling-wise, it's a sleek, attractive car that fits the mold of what regular people envision when they think of a supercar. It's wide, low-slung, and angular. Not as extreme as the Huracán, but sexy in its own right. The rear is more interesting, with its fully exposed V-8 engine out back and fenders with wide cut-outs exposing the car's bulging rear tires, a nod to motorcycle design. One area the Temerario vastly improves on the Huracán is the interior. Better materials all around, better infotainment and instrument cluster digital screens with nice animations —and more space owing to slightly larger dimensions. Fewer buttons is not a welcome change, though it seems most of these functions are now controls on the steering wheel. On the track is where it all comes together. With its hybrid system, the Temerario features two motors powering each front wheel individually, giving the car true torque vectoring. That means the wheels can spin and apply force independently on their own. This also means that, while the rear wheels are powered by the monster V8, the front wheels can provide force at different times, like during an aggressive turn, keeping the car's line true and giving extra assistance around corners. Traction is of course improved as well. So handling-wise, the car feels a lot smaller than it really is, which makes even the most aggressive track easier to deal with. But true heart of the beast is its twin turbo, flat-plane-crank V8 motor. Combined with the two motors up front and one sandwiched in between the 8-speed transmission, the Temerario has a mind-boggling 900hp on tap. The engine alone is a marvel, able to spin up to 10,000 RPM. It is designed to keep pulling to that red line. Usually, most motors will start petering out at those heady levels. This allowed the Temerario to hit ungodly, panic-inducing speeds on the straightaways of nearly 200mph, which then meant going hard on the brakes, and then into the next curve without losing it. Those front motors really helped get the car back on the proper race line if you braked too deeply into the first turn, for example. The car allowed me to string faster lap after faster lap in succession, giving me confidence to push harder into every turn, and brake later. Yes, it is overall a better car than the Huracán when it comes to aggressive track driving. And I'm sure it's a perfectly livable car too — meaning, in theory, you could take it around town to run some errands — though I didn't get the chance to drive on local roads. But I have a few complaints, believe it or not. The loss of the Huracán's V10 really hurts from an emotional point of view — the sound of the 10-cylinder revving higher is intoxicating. Yes, the Temerario at 10,000 RPM screaming down the straightaway does give you that emotional kick, but most owners will not be pushing the car anywhere near that mind-boggling limit. Most owners will be driving around town or on some nice backcountry roads. And though I said it was subjective, the styling for me is a bit too toned down too, at least compared to the outgoing Huracán. For a car that starts at $382,654 in the US, we would like more of a wow factor. Lamborghini isn't done with the Temerario Lamborghini won't sit idly when it comes to special or updated versions of the Temerario. Performance models with aggressive styling and enhancements to the powertrain may mean more exciting versions could be coming. This is all part of the game plan. And some buyers actually prefer the base models of Lamborghini's creations because they are the purest form of these vehicles. But, finally, I have to ask: Could we see a Temerario special edition combining a non-turbo screaming V8 with those trick electric motors up front, or one with an aggressive, race car-like aero package?

Professor Coin: What Gives Bitcoin Its Value?
Professor Andrew Urquhart is Professor of Finance and Financial Technology and Head of the Department of Finance at Birmingham Business School (BBS). This is the eighth installment of the Professor Coin column, in which I bring important insights from published academic literature on cryptocurrencies to the Decrypt readership. In this article, I discuss what gives Bitcoin value. In just over a decade, Bitcoin has gone from a niche innovation in cryptography to a globally traded asset with a market capitalization in the hundreds of billions. Yet despite its prominence, a persistent question remains: what gives Bitcoin its value? Bitcoin doesn't generate cash flow like a company, isn't backed by physical reserves like gold, and has no central authority guaranteeing its worth. So why are people willing to pay tens of thousands of dollars for a digital token? Recent academic research points to several factors. Scarcity and Monetary Policy The first pillar of Bitcoin's value is its programmed scarcity. Bitcoin has a fixed supply: only 21 million coins will ever be created. This limit is enforced by the network's consensus rules and is viewed by supporters as a bulwark against inflation. Academic studies have likened Bitcoin to gold because of this scarcity. Pagnotta and Buraschi (2018) model Bitcoin as a decentralized network whose value stems from user adoption and security, both of which are underpinned by the incentives embedded in its monetary policy. In their equilibrium framework, scarcity plays a key role in sustaining long-term value. Why is Bitcoin's supply limit set to 21 million? Scarcity makes Bitcoin attractive as a hedge against inflation, particularly in a world of expanding money supply. A number of economists have investigated whether Bitcoin's scarcity can explain its valuation with Kruger, Meyer, and Withagen (2022) showing the widely discussed stock-to-flow model fits historical data reasonably well, reaffirming the importance of scarcity as one component of Bitcoin's perceived value. Network Effects and Utility Scarcity is not sufficient without demand—and Bitcoin's demand comes from its use as a peer-to-peer digital asset and from the belief that others will accept it in the future. This is where network effects come into play. According to Cong, Li, and Wang (2021) Bitcoin's value grows with its user base. Their tokenomics model shows that the more people adopt and trust Bitcoin, the more valuable the network becomes. This dynamic helps explain why Bitcoin has survived multiple boom-and-bust cycles. Furthermore, Bolt and van Oordt (2016) argue that the value of a virtual currency arises if users expect it to retain value and be accepted in transactions. Their model formalizes how expectations of acceptance can stabilize a volatile asset like Bitcoin. Cost of Production and Network Security Bitcoin is also underpinned by a real-world cost: mining. To secure the network and process transactions, Bitcoin relies on a system called proof-of-work, where miners compete to solve cryptographic puzzles using electricity and hardware. This energy-intensive process is not without controversy, but researchers such as Hayes (2015) have shown that the cost of production provides a fundamental floor for Bitcoin's price. He finds that Bitcoin rarely trades below the marginal cost of mining, reinforcing the idea that energy and security provision matter for valuation. Moreover, the work of Pagnotta and Buraschi (2018) supports this by showing that mining incentives and the strength of the network's security are central to Bitcoin's equilibrium value, not just supply and demand in the traditional sense. Speculation, Sentiment, and Attention In practice, however, Bitcoin's price also reflects investor sentiment and speculation. A surge in media coverage or social media buzz can trigger price rallies or sharp selloffs. Studies by Urquhart (2018) and Shen et al (2019) demonstrate that Bitcoin prices are strongly correlated with online search trends and that trading volume in turn, drives investor attention. Similarly, Liu and Tsyvinski (2021) show that cryptocurrency returns are significantly predicted by investor attention proxies. Unlike traditional assets, Bitcoin lacks ties to macroeconomic fundamentals, so sentiment and belief play an outsized role. Macroeconomic Role and Portfolio Demand Bitcoin's value is also shaped by its role in the broader financial system. In a low-interest-rate environment and amid concerns about fiat currency debasement, investors have turned to Bitcoin as a non-sovereign store of value. This is demonstrated by early work by Baur et al (2018) who show that investors are holding Bitcoin for long periods, but is supported by followup work by Jahanshahloo et al (2025). Recent research has reassessed Bitcoin's role in portfolios, particularly in times of market stress. Corbet, Larkin, and Lucey (2020) find that Bitcoin behaves more like a speculative asset than a traditional safe haven, but it can act as a weak diversifier under certain market conditions. In a similar vein, Ji, Bouri, Lau, and Roubaud (2021) use time-varying spillover models and show that Bitcoin's hedging properties fluctuate significantly, with greater hedging effectiveness during tranquil periods rather than during crises. Professor Coin: Can Bitcoin Replace Gold? Conclusion: Value from Code, Community, and Belief Bitcoin's value emerges from a blend of engineering and economics: scarcity enforced by code, utility derived from decentralized consensus, and demand shaped by sentiment, costs, and macro conditions. It behaves like a commodity, a tech stock, and a speculative token—often all at once. That complexity is what makes Bitcoin both so fascinating and so difficult to value with traditional models. In the end, Bitcoin's worth is anchored not in what it does today, but in what its users believe it can become tomorrow. And as long as that belief persists—backed by utility, adoption, and incentives—the value may persist too. References Baur, D. G., Hong, K-H., Lee, A. D. (2018).
