Benchmark or McIntosh....

Wow! That's a lot of subs.

My only benchmark experiences are with my headphone amp, but I would agree with the general feeling that Benchmark is more about detail and accuracy, while McIntosh is more about midrange and lower treble roll off and liquidity of sound.

I'm more now then ever enjoying amps with warmth and depth and get my details out of my DAC's and tube selection.

So I'd personally go with McIntosh if choosing between just those two, but honestly I think a Parasound JC5 would do it for you.

I absolutely loved that amp and feel it's kinda of a auditory mid ground between those two brands you mentioned.

So...you have SEVEN 21" sub woofers in your room and you need a little more "oomph" ???

A bit more oomph? All these amps are within less than 2 dB of each other and 3dB more than your current amp. A bit is about all you’ll get. All you can get. While you may rightly love your NHTs, you need to take a jump up in speakers to even begin to match up to your subs. JBL 4367s come to mind.

McIntosh 100%, build quality, sound, resale, warranty, etc. you won’t regret it!
