Aesthetix IO Eclipse

I disagree with Linnlp12 regarding the volume controls. Unless you already have a *very* good preamp, I see little reason to cash out for the Io unless it has volume and the extra line input. That means if functions as a preamp. With a DAC connected to the line input, you can have several sources connected to the DAC, and switch between them on the DAC. This way you can do without a separate preamp. Several users have reported that the direct link from the Io to the amp(s) sounds great. This is my experience also, not least from the extra input, which seems to have even lower distortion than the riaa/phono input.

Sidekick_i, I have never heard the Pass so I cannot say. But I do know the Io, and do not think you will be disappointed. Great with rock as well as less dynamic music. Works well with my 0.5 v Titan i p-u. No noise problems after I got a replacement tube set from Aesthetix. Functios fine direct into my amps (Krell, now Atmasphere). Since I enjoy it a lot, I have shipped it for an upgrade, even if it costs a lot from where I live (Norway).

Re: "careful evaluation in my own home".
I could not agree more. Of course, this is the ideal. However, it cannot always be done. Especially when you move to a top level, and live in a peripheral place, e g Norway. So one has to make informed (hopefully) choices. So far, I have done well, aided - not least - by helpful discussions in this forum. Nine months ago I bought Atmasphere amps, never having listened to them, but having some experience with OTL on my desktop. They replaced a VERY highly regarded solid-state amp. At first I thought it was a flop. They needed run-in, and I needed to adjust my ears. Now, I am very happy with the new amps. I am also buying new speakers, fit for the amps, from Audiokinesis. Have I heard them? No. I buy them, based on the advice from people I trust. Likewise, I have shipped my Io for the Partial Eclipse upgrade (that is, minus the chassis), across the Atlantic, based on advice. Do I know it will work? No. But I am able to make *informed guesses* and that is not least thanks to all you fellow writers, here in this forum.

RE Io best output: XLR / balanced output sounded best with my Krell. I have not tested much with my new tube monos.

Io input (from pickup) is perhaps also best served by balanced cable? I have only used RCA / single ended (Kimber KCAG). Comments?

Oldvinyl, very sensible advice. That was my own way, and I've not looked back. How did you upgrade the umbilical cables (and was it worth it)?

Csngl, interesting. I've found I prefer the Io's pure tube amplification all the way, to others I've heard.

Chris -- I sold my Krell FPB600 and bought used Atmasphere MA-1 monoblocs here at A-gon, and got them upgraded at the factory. Although this was quite a change, and I was missing the bass at first (needed burn-in), I have not looked back. I am very happy with the OTL sound, and have only good things to say about Atmasphere and Ralph Karsten. The MA-1s turn out to be a good match with the Io.

Oldvinyl -- I use balanced JPS Superconductor FX cables from the Io to the amps. Not sure if better cables would make any big change. By the way I am now burning in the Io after the upgrade. Very interesting.
