Both are fine and it's more a matter of system balance, voicing and proper setup, than superiority of one over another.

TVC will stay in my current system, especially when I need it for single ended to balanced conversion and it is already integrated with the amps.

In in the new system I'm currently setting up, I will use PA, as I want to run multiple amps (all single ended). PA needs a source with a good buffer for proper dynamics, TVC is less forgiving in that aspect as its input resistance can be very high.

When everything is well done, PA may have advantage, as it will be probably more neutral than TVC, but TVC can still make up for the defficiencies of a less perfect system.

PA also offers more steps (128 vs 24).

Where did you get the grayhill? I have a 7gang one..but know someone who is looking for grayhill switches like that.

ps..I have not tried that many attenuators..and especially not in the same setup. But so far I like the DACT units and my Grayhill with intactaudio AVC. Next up....DiyHiFiSupply amorphous TVC's. On the same Grayhill (7gang) so comparison should be easy.
i have access to greyhills. if you need.

Unsolicited!

The one with Pins is from AMB's store, and the one with lugs is from a store in Taiwan that I mail ordered from.
