Aesthetix IO Eclipse

Hi,

I'm seriously considering this Phono preamp (with the additional line input and volume control), and would like to get in contact with potenial owners of the IO-series from Aesthetix. I believe the IO is what I'm looking for sonically (and I love the design and user experience). But, I'm slightly concerned about earlier reports of noise/hum issues, as well as riability and the practical side of things related to tube life and generated heat.

So....

- Is the IO Eclipse (still) up there among the best on the market?
- Will the possibility of driving a poweramp directly offer any disadvantages, or be as good as or better than a separate preamp of the same caliber?
- Are the tubes worth the expense, effort and potential hassle...?

What I'm looking for is a high degree of naturalness, musicality and flow combined with great dynamics and a large, holographic soundstage.

My system:

Brinkmann Bardo + 10.5 tonearm + Pi-pickup (Analog)
Audio Aero La Fontaine (CD/DAC/Pre)
Karan KA M2000 (Monoblocks)
Sonus Faber Futura (Speakers)
Kubala Sosna Elation (Cables)

Thanks!

You will not regret changing the caps (unless you choose the wrong cap :-). Everyone has their flavor of caps, I went through a lot of them for many many year. I would suggest you pick one that you know the after break in sound characteristics. Its an incredibly lot of work (understatement) but the effort will be rewarded. I dont change resistors or anything like that as I have made sound worse doing that. Some components are better than others, upgrade is just a term for "I want something new" :-). But the IO is what I consider really one of those special pieces. I did listen to it for a long time through a mod squad line drive passive and enjoyed it. Eventually went to an audio research Ref 3. The change was significant to my ears, therefore, i chose not to upgrade with the volume controls. For this reason, I agree with a comment that I beleive Albert Porter and some other person made online, go for the unit without volume controls and put the difference elsewhere.

Well, personally, I'm not very interested in turning a high end investment into a DIY-project. I prefer to put my trust in Jim White (Aesthetix :)

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.

Whoever had the Io Sig. and then sold it, def. is an audiophile. The Io is one of the best phono stages out there. Its imaging, texture, and dynamics are first rate. If you love chamber classical and jazz quartets you are in for a real treat. It is a music lovers dream. You still need great table, arm, and cartridge properly set up to get its maximum potential.

After much research and soul searching during the last couple of months, I'm going to make a final decision this weekend, where the final battle stands inbetween the discussed IO Eclipse and the Pass Labs XP-25.

In the right corner:

Aesthetix IO Eclipse with dual power supplies

+ the beauty of tubes
+ superior build quality and aesthetics (IMHO)
+ additional line input (for a digital source) making it a fully functional preamp (which in the end almost justifies the price...)

- twice as expensive as the Pass
- large boxes - 3 in total
- a LOT of tubes, which means a lot of heat and potential sources of hum and/or failure

...and in the left corner:

Pass Labs XP-25

+ half price compared to the Aesthetix
+ less (and smaller) boxes - 2 in total
+ less heat and less potential problems...

- no additional line input (which means you'll need a dedicated preamp for a digital source)

Your advice please.

Many thanks.
