    I have a set of speakers from my HT setup I can steal for now, and a Dragon Fly Red that I usually hook up to my SE846's. I plan to attach them to my PC sometimes depending on what I'm doing, but I'm missing an amp.

    Could someone suggest something that is relatively inexpensive, small and good for listening to vocals and classical?

    I was looking at For Sale - Cambridge Audio Topaz SR10 in black - PRICE REDUCED but not sure if it would be suitable.

    Thanks

    The LS50s have a reputation for needing some serious welly to sound at their best... do you have a budget in mind?

    Hmmm, I think maybe under £300. I don't plan on having these on loud since I'm in a terrace..

    The power isn’t for loudness as such, but for proper control with a big music signal at a low impedance part of the speakers response.

    Keep an eye on these few. They’re all powerful enough to get a good sound from the Kefs.

    Cambridge Audio 651A Integrated Amplifier (Black) - Refurbished 5055300412058 | eBay

    But, with any luck this should sell for around your budget and, if you can stretch to it, is a serious amp of the calibre the Kefs require.

    Thanks for this, given that so much power is needed, is the Marantz SR6012 I currently have them plugged into enough?

    I've got the Musical Fidelity X-A2, which is essentially the X-A200R without the remote control. It's a pleasant amp and more tonally neutral than the Cambridge (I used to own a Cambridge 640A driving identical speakers), but in terms of current, drive and bass grip, the Cambridge was the superior out of the two and it showed it in rhythm and timing.

    I’m surprised at that.

    However, the XA-2 was more of an upgrade on the X-A1, whilst the X-A200R was an upgrade on the XA-1000R.

    An altogether more powerful amp.

    Having said that, and though I think the 200 is impressive, the 640 and 650 CAs do play in a higher league than their price suggests.

    If budget was my ultimate test, I’d go for the 650, or the 640.

    When I had the Cambridge system it was very revealing, and with certain genres (principally electric guitar based music) or with poorly recorded material, it could sound harsh in the treble, but I put this down to the CD player more than the amp because when the amp was playing other sources it was fine.

    For the money they asked for it, it was an awesome amp and comes highly recommended now as a low-budget used buy. I know some people reported reliability issues, but I bought my 640A in 2004 and it's still going strong with its second owner.

    Actually you could probably pick up a system comprising a Cambridge 640A and Ruark Epilogue speakers (preferably the rarer MkII's that have the Ruark label ontop the speaker rather than on the front baffle) for £200-300 all in, and it would merrily trounce many other systems I've heard up to and beyond a grand. It sounded awesome with movies too.

    I had the sr7010 avr and had 3 ls50's across the front. it worked but they sounded their best on mono blocks pushing serious power into them.

    as @Paul7777x said, they work best with power behind them. the issue with the ls50's is that they are very revealing and show up bad recordings etc. it's a double edged sword to a degree.

    I currently own an AS500 Yamaha amp, would this amp be suitable for the LS50s?

    I ordered the CA 651A. But what do you guys think of the new Sonos Amp, seems like there is enough power there...but a little above my budget..but then again, if £600 is the budget, it probably opens up a whole host of other good amps that are out there..

    I’d try the 651 first. It may be all you need.

    I’d be interested to hear what you think after becoming accustomed to it too. :smashin:

    It's arriving today, so I'll give it a try tonight. The 651A looks like it has a USB input, so do I still need to use the Dragon Fly Red to feed it?...

    Try them both, see if you notice a difference.

    The CA is an older type of usb implementation but there’s no reason to suppose it’s better or worse because of it.

    I think it will be limited to 44.1/16, but I’m not certain. Nor is that likely to be important.

    In a NEW Amps with reasonable power based purely on High-Value, at least consider the -

    Yamaha AS501 Integrated Amp w/DAC, 85w/ch, Phono-In, Sub-Out - £260 -

    Yamaha A-S501

    That is about the most amp at the best price you will find in a New Amp.

    If you want to push your budget, consider this Network Streaming Receiver -

    Yamaha RN602 Network Receiver, AM/FM, 80w/ch, Network Streaming, DAC, Phono, Sub-Out, etc... - £320 -

    Yamaha R-N602

    Best value in new equipment.

    I will agree with others. The Kef LS50 are fine award winning speakers and deserve a great amp with decent power, unfortunately, your £300 budget does not push you into the range of amps deserving of £800/pr LS50 speakers. Add £100 to £200 to your budget and now we are talking, though adding £200 to £300 would be better.

    But we have to work within the budget we have. We've all been there ourselves.

    But, again, Yamaha maintain a pretty reasonable standard of quality and they offer most for the money.

    Maybe I'm late to the party but if you use your dragonfly out of PC you can do proper vol control with the PC using PC/dragonfly as a preamp. You could therefore buy a power amp, plenty of powerful ones available at 300 I would think
