Customer Ratings & Reviews

I have owned quite a few audiophile amps; tube integrateds & separates from Primaluna, Jolida, audio research and quite a few solid state behemoths like Krell, Rotel, etc. Nothing compares to sound quality of the Yamaha as2100. I was delightfully surprised at its presentation. A perfect balance of resolution, warmth, tonal color and frequency extension. Build quality is equally pleasing both the aesthetics and tactile feel. I like the phono stage too. It is on par or better than some ~ 1k standalone phono stages. My LFD phono stage has only a slight edge over the built in phono of this unit. The built in phono beats the discontinued PS audio GCPH (1k when new). This is undoubtedly a true high end amplifier and definitely recommended to audiophiles.

Great amplifier with clear highs and deep strong bas,only one small suggestion - Something you should know about this amp.It uses relays when switching from loudspeakers to headphones .The same is with input selector.Now this might be a problem - if relay stays in same position many days or weeks,the contacts might oxidate losing tight contact and sound become poor - sharp highs and poor bas.My suggestion is - every time you want to listen music plug in firstly headphones for a second and move the input selector in any position and then turn it back in position you want to listen - doing so you are cleaning the relay surface from ultrathin oxide coat...you will be amazed what difference does it make
