Aesthetix IO vs. Manley Steelhead vs. The Groove


For those who have heard at least two of these, please compare the sound quality of any of the following three phono preamps:

1. Aesthetix IO or IO Signature
2. Manley Steelhead
3. The Groove

Let me know what you think of the sonic biases
and flaws in these products as well as what each does especially well. Any t/t and cart recommendations which work especially well with any of these would be recommended.


Thanks,

Your question about the sound of a retubed unit:
I use a Callisto Signature withe NOS Telefunkens ( 12AX7 ), Mullard (EL34) and RCA (5692) tubes very close to these above.
It simply sounds real ( natural ? ), the soundstage is bigger and more open, the dynamics is improved and it is simply not possible for me, to go back. I can not find any weakness.

It is like another owner once wrote me, that it is simply impossible to be without it.
(And I seriously think about purchasing an IO sign.)
I believe it. But Frank is still in hiding. Or blissfully listening to the IO and deaf to this exchange.
Not ignoring anybody, just busier than all get out! Ya wanna know just HOW busy? Here's the proof:

Date: December 11, 2003:

Obsessive/compulsive audiophile pays extra to have $1,365 of NOS tubes shipped to him for receipt last Friday (obviously to play around over the weekend), and here we are on Monday night and he is at work with only a 50/50 chance of getting them installed tonight!!! Oh the HORROR!!!!

So, if I can do the ONLY decent thing and ignore my wife, my appetite and my employer tonight, I will FINALLY hear the magic!!!
