While I like my .7s, what I really like is acoustic music. I honestly don’t think they are the best choice for amplified rock and the like. Also, when I auditioned the .7 at a local dealer (lucky me!) with a Rogue Sphinx, a Node was the source. I was so disappointed from the first sound I heard. So was my wife. I asked to change the source to turntable and CD. Much better. On any good system, weak sources or recordings get shown up. My DAC, a PS Audio Directstream, is the most expensive component now in my system. I didn’t plan it that way, but that’s where the search led.
If you ask me, I think there are many, many fine amps that don’t cost a fortune. Picking the speaker that fits your own ear and music preferences — and your room — sets the stage. And then feed the system with the very best signal you can afford, meaning good recordings and a good TT cartridge and a good DAC. Best of luck in your search.
