Please advise on second amp for my B&W 801 S2

The more the power the better the sound.
I have McIntosh MC275V mono block to drive my B&W 802 diamond for the last couple year and added a second pair of McIntosh MC601 last month to compare side by side. The different is huge especially you have a such large room and I also enjoy filling the space with sound.

Are you thinking of doing this to deal with the harshness in the high frequencies, or is there no problem and you just want to play your music louder?

make sure that the VK-55/60 has the same input sensitivity & the same (voltage) gain as your existing amp so that both amps will drive the speaker inputs with the same voltage level.

Thanks for the comments and info.
The primary reason for my interest in the addition of this VK-60 AMP is increasing overall performance (sonics/how musical, influence on highs and mids). I am also interested in learning how the tube amp handles the additional WATTS.How WATTS influence volume.. My BAT preamp tops out on volume at 140 on the dial, I can comfortably listen at 105. I am not concerned to go louder as much I am interested to see how the additional amp will influence sonics and overall performance.

The VK-500 has a low input sensitivity of 87 ish, so I need to find out the level on the VK-60. I was interested to see if anyone was currently using this combination.

no, that's not what I meant. I meant what is the max input signal in volts to get the max output power.
For example, for my amp it is 1V for max power of 300W into 8 Ohms.
what your volume knob setting is does not matter.....
if this info isnt in your owners manual, call up BAT. I'm sure that Victor Khomenko will advise you correctly....
