Your Favorite Sounding Power Amp, $5000 US Retail max.

I have been extremely happy with my LSA Voyager 350 GaN amp, which is on sale right now for ~$2600, including a power cord. If you want to spend double that though I doubt you will get 25% better performance is the new AGD amp MSRP ~ $5,000

The LSA Voyager 350 GAN is really good. It does not have as much bass power as the CODA #8 but it has a bit more detail. I sold the Voyager and kept the CODA #8 since I wanted the extra bass.

Definitely Parasound JC5 OR A21+

re "Van Alstine DVA M225 monoblocks - ~$3400 for the pair. Factory direct made in the USA. "

I read that review and was intrigued. The reviewer is an audio recording engineer and an experienced high-end reviewer (he put them up against Pass monos). I am surprised that there haven’t been more reviews... some of the other Van Alstine products have been chosen for multiple "best of" lists. I keep looking here for reccs by owners of these.

I love the size of them (similar to the small/light Benchmark amp)... perfect to place next to each speaker, and they are balanced with XLR connections.
