I have a modern Yamaha A-S701 integrated amplifier for sale. It is in excellent condition, works flawlessly and sounds great. A Google search will find great reviews of this amp. All the modern features plus old school styling. It does have a bit of a laid back top end which works well with the Klipsch speakers I have tried. Two digital inputs, sub out, detachable power cord, nice remote, 100 watts per channel etc. The variable loudness control is a nice feature if you like to tailor your sound.
