Selling a Hafler XL 600 power amp. It is very good condition with a few scratches on top Faceplate is nice. The power on light seems to be burned out. Unit fires up and is quiet The fan comes on at slow speed on start up and is pretty quiet. The XL-600 is the most powerful amplifier to bear the Hafler name. This formidable unit, which is rated to deliver 305 watts per channel into 8 ohms from 20 to 20,000 Hz with no more than 0.05 percent total harmonic distortion (thd), is not current-limited. Its rated output at the clipping point is 360 watts per channel into 8 ohms, 500 watts into 4 ohms, 750 watts into 2 ohms, and 900 watts into 1 ohm! It also has a bridged mono mode in which it can deliver 1,000 watts into 8 ohms or 1,500 watts into 4 ohms (at the clipping point).
The XL-600 was designed to use some 30 dB less overall negative feedback than previous Hafler amplifiers, which contributes to its low transient intermodulation distortion (tim) and high stability. In accord with Hafler's "Excelinear" concept, phase shift in each channel has been kept to a minimum. Each output stage has eight power MOS-fet's (metal-oxide-semiconductor field-effect transistors) capable of driving the most difficult speaker loads. Except for the single large power transformer, the two channels are completely separate, and the total filter capacitance of 72,000 microfarads gives the amplifier a powerful low-end capability. A small, separate power supply operates the low-level stages.Located in Twin Cities Shipping nut a problem

I have one of these, you could use it as a welder, it has plenty power, sounds excellent. Plenty of upgrades are available for it also.
Don't see these often.
2 channel: Anthem 225 Integrated amp; Parasound Ztuner; TechnicsTT SL1350; Vincent PHO-8 phono pre; Marantz CD6005 spinner; Polk SDA2BTL's; LAT International speaker cables, ZU Mission IC's and power cables all into a PS Audio Dectet Power center.
Other; M10 series II, M7C's, Hafler XL600 amp, RB-980BX, Parasound HCA-1500 amp , P5 preamp, all in storage. All vintage Polk have had crossover rebuilds and tweeter upgrades.
The best way to predict the future is to invent it.
