I have been running a Yamaha A-S1000 for about two years now. Source devices are a Thorens TD 160 + Denon 103R, Cambridge 651c CD player etc etc.
* Built like a tank!
* Very, very clean sound - I'm hard-pressed to find differences in sound to my Dynaco Mark III tube monoblocks
Neutral to the point where British taste would probably consider it TOO neutral (seems to me the Brits like harsh sounding amps).

I call this the BEAST. It has power like nothing else, looks the part and weighs a ton. It will not fit most furniture due to being very deep so consider this when purchasing. Phono stage is very very good, from my experience it exceeds separate ones costing £300-400. The only downside is that the lowest frequencies (under 40HZ) are recessed so if you are into hip hop or EDM look elsewhere. If those genres are not your cup of tea then this must be on your shortlist.



re: A-S1000

Couldn't agree more.

Love my A-S1000, built like a tank and powered like one. I run a Pro-ject Classic t/table with a MM cartridge through its phono stage. For digital files I use it as a power amp with a Burson Virtuoso DAC/Pre-amp feeding through its main in. CD's I play through a variety of players depending on the type of music, a vintage Mission, Yamaha CD-S700 and Marantz CD 6006. The unit powers a pair of KEF Q300's which I find have great low range & really complement the amp. If you're into warm, detailed, neutral sound that can blast your walls down its a go-to for the price. If you can find one these days.

re: A-S1000

One more thing I forgot to say, after a long time I've noticed that Line 1 and 2 sound a little worse than CD, so if you are testing make sure you are on the CD source.
