I took a bullet train across a large chunk of Japan today to listen to a minty pair of Guanari Homages. MAN! What everyone says about they're kindness to the ears is really true!
I tried them with a Goldmund Mimesis 27ME Pre through twin Mimesis 8.2 power amps, and also with a Krell KSL-2 pre through the Goldmund 8.2's, in comparison to a Luxman L-550, my current amp, which is leagues lower than those in price and specs.
Both of the fancy amps were more detailed than my old Luxman. The Krell hit some shrill notes on violin concertos, female opera singers, and trumpets. Mind you, "shrill" through the Guaneris was a relative term. Much sweeter a "shrill" than with most speakers. I didn't like the sound so much with that Krell.
I was happily surprised that the highs through my old Luxman amp sounded nicer to my old ears than that super-pricey Goldmund stuff. The Goldmund stuff drove the bass better, thus making the music seem fuller, but the Luxman has trusty old tone controls, and turning the bass knob up came close to sounding just as good, as far as I could tell with ten men blabbing in Japanese around me, four men packing speakers with loud packing tape, trucks passing by the open doorway, and others trying speakers throughout the listeningroomless shop.
Classical strings, guitars, and human voices were second to no speaker I've ever heard (and that's LOTS). Somehow pianos didn't sound quite real to me, though, something I've found on all SF speakers I've listened to. They sound a bit too sweet, soft, and distant, lacking power and "wood" to me.
Some old Aretha Franklin, Beatles, Doors, and Cream albums sounded better to me than people say these speakers do rock, but Gang of Four and Stanley Clarke bass-slapping didn't quite cut it. There was definitely a lack of "slam" through these with the equipment I tried, but I listen to that sort a lot less than other genres.
There is a magical way they have of drawing you in, though. Humans are SO human through these. Acoustic instruments sound SO good. Lots of people who were there for other reasons or were supposed to be working sort of slouched over with comfy grins when I played Cassandra Williams or Eva Cassidy.
Overall, I'm very tempted to risk divorce (PRICE!!!) and buy these. Wish I could hear the much cheaper Minimas first, but those are just as rare here in Japan, apparently, and if I don't knab what's available its a year wait for the next pair....
