Am looking hard at PS Audio's M700 monoblocks and then I saw some amps by ClassDAudio for way cheaper. Seems like the same products are developing for class D amps like A/B has. Some cheaper and better, some cheaper and not so good - some more expensive and real good and some expensive and just ok. I bought a little Lepai 100watt class D amp and was greatly surprised by what it could do. On 4 ohm speakers. Authority and musicality are what I am looking for in an amp. Looking to drive some Genesis 5.2 speakers. Presently am using Bob Carver VTA-180 tube monoblocks or a Parasound 3500. But, the class D amps are really pulling me to try them. Just don't want to take a big step backwards nor go through the expense of learning as I buy scenario. Smaller and cooler is what attracts me so I can reduce my systems footprint. Thoughts/Experiences?
