This is truly an uninspired product that can be bested sonically by a Lepai TI2020. Certainly by an old Audiolab 8000a which one can purchase used for the price of this. None of the character of that old Cambridge product comes through in this tin sounding, sterile and dull receiver. It is merely a switch box with a Chinese amp circuit that is commonplace. I guess my expectations were too high. The sad thing is, I was going to audition the CXA81 for another room. Based on this amp? Not a chance. For $200-300, a Yamaha anything should exceed the performance of this. Heck, my kids Sherwood RX 4109 does and those knock around for $50-$100.

What I find most appalling is the phono stage, here Cambridge has succeeded in creating one that makes phono sound uninspired and dull. Much like a compressed mp3. Granted my impressions were informed using an LP12 and then Systemdek IIx, so flaws in the phono stage might have sounded even more exagerated. It likely would sound better if hooked up to a 1970's bsr changer, which sonically is this piece of kit's equal. This is not for someone who enjoys music for it's own sake, but someone who merely enjoys low level background sound on tiny table top audio engine like speakers. Read full review...

The SR20 is the most powerful amplifier in the Topaz range offering an immense 100 watts per channel, backed by a dedicated subwoofer output as well as two sets of speaker outputs. It also features analogue inputs, digital inputs, a phono stage, an FM receiver and an MP3 input, so it will connect and play virtually anything you throw at it.

VINYL PERFECTION

Continuing the comprehensive specification and attention to detail, the SR20 features a built-in MM Phono stage, bringing your vinyl to life! Turntables fitted with phono cartridges of either the Moving Magnet (MM) or high output Moving Coil (MC) type (between 2-6mV output and 30-50k load impedance) can be used.

POWER IN RESERVE

We strive for audio perfection, which is why SR20 features a powerful toroidal transformer. We were one of the first manufacturers to use toroidal transformers in the 1970s, and we continue to use them today. Some of the benefits of a toroidal transformer, over the cheaper, inferior EI transformers used by most other manufacturers are:

High quality power output to the amplification circuits, with no clipping, transformer noise, buzz or hum, to provide a consistent signal High power output, to allow large and demanding speakers to be driven at high volumes with sensational bass performance Large power reserves, to allow the transformer to deliver high peaks of volume when required Fully shielded against internal and external electrical interference, to maintain quality of power and signal

ALL METAL DESIGN

Electronics (and therefore sound quality) are particularly susceptible to vibration; that’s why we’ve used a low resonance, acoustically-dampened metal chassis to eliminate as much vibration as possible, ensuring that the most sound quality is extracted from every source.

Anyone seen or compared any measurements of the Cambridge Audio SR20? What hi-fi seemed to think the SR10 lacked some "detail" and "organisation" so belonged squarely in the budget range, but I also know such reviews should be taken with a pinch of salt. Would one even tell the difference between it and a higher priced unit? I'm trying to determine whether it is worth buying or whether I should save a bit more or keep a look out for something better. It's on sale so the price is good but I wouldn't want to compromise just to save a few bucks.

Any info or experience with such a unit? It would be replacing a slightly old Marantz SR4003 AVR (running stereo duty). I need a second integrated amp for a second zone so thought I'd grab this as a potential upgrade to the SR4003 which I will then relegate to the second zone.

Any other recommendations?

I would not rely on What Hi-Fi's subjective impressions. They are into too much woo, always have been.

None of which is to say that the Cambridge sucks. But you should look at online resources with good measurements, and choose the best from what you find.

I used to upgrade their phono stages, they used cheap Chinese Xunda capacitors inside, there nothing special.

That's disappointing. Whilst it is at a decent price I would rather get something decent. Unfortunately the used market here is fairly limited so I wouldn't hold my breath hoping for any specific used model like the Yamaha AS700.

Indeed, that was exactly my point, don't trust most reviews, I mean what does it mean that an amp isn't "organised" anyway? That's why I asked here, I couldn't find much in terms of reviews or measurements when googling for them.

And yet @amirm did recommend their phono when he measured the Cambridge Audio Duo Phono

  And yet @amirm did recommend their phono when he measured the Cambridge Audio Duo Phono

Summing up what Amirm said, I would conclude it's nothing special:

"The Cambridge Audio Duo phono preamp comes in an attractive package despite its budget price and branded label. Its amplifier is essentially distortion-free and performance is mainly limited by power supply hum/mains leakage using MM input. MC incurs a penalty of 20 dB so you may hear some hiss there that would not with MM.

Sadly the headphone stage is a throw-away design. You can use it in a bind but don't be surprised if it has too little power/too high of a noise floor.

The Duo seems to be competently designed and attractively priced so I am happy to put it on my recommended list." - Amirm.

  Summing up what Amirm said, I would conclude it's nothing special:

Oh, okay, fair enough. I was going from the bit from the Schiit phono review where he said his strong recommendation is for the Duo, but I guess that is considering its price and comparison to the Schiit.

"The Schiit Mani seems to be competently designed. I find no clear flaws in it. For sure, it sets a lower target then the Cambridge Duo and gets there. If you can save up US $299, my strong recommendation is for the Duo but otherwise the Mani does the job for a budget phono stage." - Amirm.

Either way, seems like I need to keep looking for a decent budget(ish) integrated amp, preferably with optical in and two zones.

At the more affordable end of their product range Cambridge major on offering nice feeling products which offer good features and decent performance for modest cost. They are not the best but for what they are they are pretty good products and I suspect most of their customers are satisfied. They offer something to UK customers in particular (I can't speak for anywhere else), they are the house brand of a major hifi and AV retailer with good reputation for service and customer care. So if I was to buy one of these and it had a problem I could drive 4 miles to the local store and based on my past experience be pretty confident they would resolve the issue. That in itself has a value.

I have an SR20, and I will recommend it as a decent amp for its features and price. It will hold up pretty well to anything else you find in its price range (under $400).

It has a built-in DAC that handles up to 24/192, MM phono stage, 3 digital inputs, 3 analog inputs, 3.5mm aux input, FM tuner, headphone out, dedicated subwoofer out, and A/B speaker outs. It has plenty of power. Cambridge builds solid stuff, so its build is really nice and heavy, not like a budget amp at all. The SR20 looks OK, but I kind of prefer the look of their older amps without the dinky digital display.

I use it with a U-turn Orbit turntable for analog, with a HifiBerry Digi+ Roon endpoint for digital, and I run my TV out through it too. KEF Q150 speakers at the moment, but I've used it with a variety of others. It just works and sounds great.

I guess we could put it into context by saying I can go to my local store and buy one of these for £299. It's a decently made product that appears to do what it says on the tin and I suspect that despite any measurement short fall in reality the amp and DAC will be pretty transparent and of sufficient power for most. On another thread we have a DAC which displays...ahem...less than great measurement and costs 13,000 euros. Without the amplifier.

I have Cambridge's high end 100W on my bench at the moment. Although it has insanely good distortion performance and superb build quality (and is easily worth its $3k pricetag, IMO), I'd question whether it will actually

sound

better than the cheap version assuming your speakers aren't pathological.

The SNR is referenced to 2.83V and is fine for a power amp. If it's noise dominated and you have some worst-case speakers (say, 100 dBSPL/2.83V/m), the noise from the speakers will only be 18dB SPL at a meter, and far less at a normal seating position. That's lower than nearly all listening rooms. For something more typical like 90 dB/2.83V/m, that drops to 8 dB SPL at a meter, and no way you're likely to hear that.

Bottom line is that this amp will likely work well for you and not cost an arm and a leg. Magazine "subjective" reviews are worse than worthless- don't let them influence you.

Thanks for the input. So doesn't sound as dire as it may have initially seemed. I guess the comment around the SNR put me off a bit but I guess, as @SIY said, it won't be audible at reasonable listening position.
