Passive Pre - No Regrets?

Unless I missed something, all of this talk of transformer vs. autoformer is pure speculation. I don't see where anybody posting has actually compared.

Neither have I, but the link I gave to Intact Audio has an active forum with people I know, and who's ears I trust, who's passion is transformers and inductors, and FWIW they say there is no contest; an autoformer is clearly superior to a transformer when used as a volume control.

I don't see this as a drawback as the issue with DC is no different if you use a resitive voltage divider of some sort.

Darkmoebius: Yes very short speaker cables I actually have built a pair to my flavor mixing copper and silver transformer wire, right now I think I am missing a couple of copper strands to give it more body. The ICs are Gabriel Gold bought here in Agon, I also have Nordost Blue Haven but they are a bit forward and shy on bass, I tried Siltech SQ80 and they were too dark, Black Mountain were too light..Gabriel mixed good in my system, 1 meter between DAC and amps. 4 inches one strand kimber blue (from 8tc) from the attenuator to the input tube inside the amp :-)
I got the PLC partly because I got a good deal and because I heard better reviews of autoformer vs transformer...since I got the perfect setup for passives I might give the transformer a try, probably the Promiteus Audio since they are affordable. (say against th 6.5k for the AudioConsulting)
Atmasphere: I find Pubul57s question very ineteresting also, If you could design the perfect source-preamp-cables for your amps, would it be passive or active?

Thanks

I wasn't dawging the PLC..only pointing out. One shouldn't confuse the two. Whether one is superior to the other is in the ear of the beholder. Hey Jsadurni..if the Promitheus doesn't work out for you. I'll buy it from you for what you paid for it. I already know the out come..once you get it, I'll have to pry it from your cold dead hands!LOL

Good listening

But, both Autoformers and resistive pres are significantly different than a TVC in that regard. Galvanic isolation means that no DC will pass through the TVC at all. Of course, I think most sources have a capacitor near their output specifically for DC blocking.

Anyway, it's best to absolutely sure that no dc is being passed by all sources before making that very expensive leap of faith.

Another major TVC advantage(if needed), is that they can easily convert single-ended signals to fully balanced for driving very long XLR cables with little signal degradation. A big advantage when your equipment rack is on one side of the room and amps next to the speakers on the other.
