I have tried a Spectral preamp/amp, Transparent cable system in a previous system. I have owned 28 different amps in the past 12 years. Give Spectron a look. A digital amp that has quickness ( slew rate, rise time ) and neutrality. It allows you to voice your system however you want to. Power output is tremendous with over 600 wpc. Does things other amps and digital amps cannot. I needed to have a lot of convincing to even try a digital amp. No bits chopped here. It is glorious now that I have tried it. It never went back. Try Galen Carol Audio to take one for a spin and a fair deal, gcaudio.com.
