How is

@millercarbonI don't know why you believe someone needs to spend $20,000 on a pair of monoblocks to get good sound? 

I run a pair of Soundcraftsmen PM860 monoblocks that I paid less than  $500 for. Yes, they're 40 years old. But they put out 900 W at 4Ω (which my Martin Logan Spires love).  I drive them them with a 6SN7 tube preamp (Don Sachs Custom Linestage).

I also have a pair of rebuilt Golden Tube Audio SE-40 monoblocks (75 W). While they do not match the 'slam' of the PM860's, they are very musical. The cost was $400 for the amps, $1,500 in upgraded parts (caps, resistors and tubes) and my time spent soldering, for a total under $2,000.

Yes, you *can* spend $20K on a pair of amps but you don't *have* to.

One monoblock to each channel.  Right monoblock, right channel, left monoblock, left channel.  Nothing complicated about it.

MC, I got a laugh from your response. But, I guarantee you this: In time, you too will have monoblocs, and you'll be telling everyone that it's the only way to go.

Here ya go! Why would you need shorter speaker cables and longer interconnects? My tube mono amps are in the same location that my stereo amp was located!!
