Aesthetix IO Eclipse

My Io runs much hotter than my friend's Karan new 2000 watts
monoblocks. Both Aesthetix units will generate a lot of heat
so I imagine that you probably want at least 3 if not all 4 sides open as much as possible.

OK, thanks. May I ask (out of curiosity) what your friend is partnering the Karan monos with?

Sidekick, My friend is using his Karan with Magico Q5 and ARC 40th Anniversary pre. Can't comment much on the sound yet as he just had his listening room rebuilt and the amps are still not burn in completely yet but the bass and dynamic on his Q5 is just about the cleanest,tightest, most controlled that I ever heard so far.

Interesting :) I believe Karan has sold about 10-15 pairs of the M2000 world wide so far, which makes them quite exotic. I've had mine for about 2-3 months now. They do need quite some time to open up and "relax", as they did sound rather stiff and hard around the edges at first. They're also extremely transparent and a hard judge on their partners, which makes careful matching critical.

I had a regular IO single power supply that was just upgraded to the eclipse sig it went in for repair because it sounded so bad they needed to change so much the upgrade made sense, well it saved me some cash and I didn’t want any issues I wanted to sound great after all the previous issues and time I spent so I gave them the ok. Thousands of dollars later, got it back nothing but trouble the thing makes so much noise I can't listen to it! I borrowed a $500 little photo stage and it sounded so much better. Didn't have the depth the IO had but overall so much better only a little hiss. I am back about 15’ from my vandersteen 7 and I hear a pretty loud hiss and crackling in the the channels now ans then. Aesthetix then sold me more tubes thinking the tubs got bounced in shipping for several hundred dollars! Still makes the same noise quieted it down maybe 5%. I have spent no less than 80 hours swaping tubes and doing everything under the sun to make this wok because I am in it for so much cash. I am so frustrated with it I have not powered it up in months I would never buy this pre amp again. I think my system is just to sensitive for it maybe if I had less sensitive speakers but I hear everything and although the sound is big and live I can’t get past the noises it makes. I don't see how anyone can even here space and blackness over the pops and hiss.
