Monoblocks did not work

Help me with this problem pl. I had one Classe CA-400 driving Dunlavy V'S with all Classe front end. I was very happy with the sound, so happy I refused to upgrade for 3 years. That the power bug hit me. What if I buy another CA-400 and run each as monoblocks. I did, with all other components remaining same( same IC's going to each amp). The result was way worse than expected. Thin , hashy, ambient sound. Power of 800W/ch (into 4 ohms) became 2400 W/ch, still bad sound. What happened? How do I make use of the beast (120lbs) that I have aquired?

The best solution for you and your equipment is to bi-amp horizontally. The most obvious reason is the by doing this, (using one amp for the lows and one amp for the highs) it puts the least amount of stress on the amps by using both channels equally.I don't think that you will experience any negative sound affects. Overall, I think it will sound better.
Good luck.

I think your terminology is incorrect. Horizontal (amping) uses both channels of one single amp to drive the low freqs of both speakers, so you end up with one stereo amp driving the lows and one stereo amp driving the highs.Is this what you mean?
