Hi all, Had the chance to try out a couple of preamps recently A modified Goldpoint passive and a Slagle Autoformer preamp The GP has solid silver wiring and Z-foil resistors. When I plugged it in it sounded incredibly detailed and open but quickly began to get fatiguing. It was almost too much at times. This could be a compatibility issue with the Jolida phono stage as it sounds to me to have gain overload resulting in distortion. The AVC is build into a perused box and is copper lined. The Slagle was just as clean sounding but is very musical. Delivers the music with a great sense of timing and pace. I am incredibly impressed with it and have bought it. I'll get some detailed pics up a bit later.   |

Is the Slagle just an auto transformer or is there an active buffer in there?

Thanks. You may need to watch your cable runs to minimise hum and noise pickup, although a transformer should be better than a passive volume control in this respect.

I had a pair of promethius mono tvc's in for repair for a customer of mine and they were very very good indeed.
As some of you guys know, I build custom passives as part of the product range I do, so I get to listen to loads of different attenuators, pots, tvcs ect, and I was very impressed with the tvc's. Once id fixed the bloody things :-).
They are rather time consuming to build, and they do cost alot of money for decent tapped transformers, but are a very good option
Cheers ant

It's fine in this case Ant, as you were asked a specific question about your product/s.
