Aesthetix IO Sig V 2nd power supply & Lamm LP2 del

thanks guys. BTW, I don't own the IO, just listening to it from the dealer.
Tube noise and reliability are both issues, however the local guy who does the repairs on the IO, owns an IO and he says it is very reliable, so I feel more comfortable about owning one in Australia.

Rushton, Are you saying you have used your original tubes for 5 years?? How many hours a week do you play??

From reading the Lamm is a little warmer sounding than the IO??, or just a little darker - not sure what the difference is.

ON the Lamm side I can buy a 2nd hand unit as they are changeble to 240vlts, the IO you must use the 240vlt version made for Australia.

cheers

Hi Tim

good question. I think I will get the PH7 back for a another listen as they are in the same league.

I can comment on a couple of things thou.

The IO's bass is more dynamic and bigger in size, whereas the PH7 is a little tighter and does not have as much impact. For my musical tastes, the IO is a step ahead in that area.

Mid's and hi's, not sure one way or the other as I have new speakers, but the IO does seem to have a bigger presentation overall.

Both are more musical than my Xono, however both a lot noisier.
The PH7 only has 57.5 db gain (same as the Lamm), so I want to re-try it with my new speakers as they are a little more efficient.

At high volumes I remember I could hear slight transformer noise from the PH7.
From the IO, even at 62db, you get that wonderful ( not!!) tube rush - but no other noise. Please note at normal volume's you can't really hear the tube noise, but at louder volumes you can hear the tube rush between tracks and I would guess on quieter music tracks. I am not sure I can live that again. I used to have a cj prem15 and that was noisy like this as well.

Only really listened to it for one night, now I have the flu so everything sounds like crap - but the IO bass does rock thou.

I'll keep you updated.

You state that you put the gain back to 60db??

In IO manual I have here the gain stating at ATT1 and going to ATT5 is 80, 74, 68, 62, 50. My manual says IO, not sig so I think it is an old manual.

Are impedance's from jumper position 10 - 1. 10k, 4.75k, 1k, 475, 243, 121, 75, 40.2, 20 , 10

Is anyone's else's manual different??
