audiopax Model 5

I think, you might have misread: colourful as in rendering colours vs coloured as in sounding veiled.
I find the A'pax very transparent, i.e. not coloured, except in direct comparison with probably the most transparent preamp existing, the Audio Consulting Silver Rock passive TVC.
On the other hand it does seem to render more colours.

'that clear?

;-)e

Clear like colorful glass! So what types of things sounded different with the new power supply?

..that is actually quite easy, it is really much quieter.
On a more careful note: It does seem to be more substantial in sound, and this is exactly not completely sure where the line goes in comparison with the Silver Rock TVC.
The incredible thing is, you can finetune it with the Timbre control, which according to your mood can be fabulous or a true bore, as you can never leave it alone ;-)
So, using the Audiopax will show your character!

you are looking to sell the 5? $$$???

I just acquired a Model 5 SE - sounding very good - very transparent.
