Passive Pre - No Regrets?

Pubul57 If you want to get a feel of the passive you can get a Luminous Audio passive, they supposedly calculate the impedance and sell you the passive, it is a shunt passive with a pot to ground, A friend has one and it does let you get the feel of a passive...full resistor loaded is much better, I talked to Guy from Placcete and he told me all his passives come with a 10k impedance, this impedance can work for you, he also changes impedances according to the customers settings. You can buy a placette passive and see if it "fits" your system, Guy will help you out even if the preamp is used (very cool guy!) this way you can be sure you have the passive matcing properly.

Just from what you've told me. The TVC should work just fine with a 100 ohm input. Here's a FAQ's page from Promitheus on how TVCs work. Unlike resistive type passives a TVC will actually lower the output impedance and increase current drive from your source or BAM. Hearing the difference between it and a pot or ladder resistive attenuator is very easy. You get a fuller sound at lower SPLs with a TVC.

I should have a Bent audio unit with Stevens & Billington TX102 trannies in for a comparison within two weeks.

Now THAT I want to hear about....;-}

Hello Gmood1!!
Have you tried a resistive passive vs. a TVC in your system lately? I had a hard time but I finally got the match made and the resistors betters the TVC in my system, Im curious about your findings.

All the Best

Hey Oz...yup I'm looking forward too it myself! I've found one owner of the Promitheus TVC that has compared it against a Bent Audio. From his post they sound about the same too him.

I'll see and hear for myself thanks to a nice audiophile friend who has many audio toys. If they do come up fairly equal..the Promitheus will be one of the best bargains in HiFi. For $280 plus $60 shipping it has shamed all the actives or resistive passives I've played with period.

Jsadurni,
The only resistive passive I've compared the Promethius too lately, has been the Noble pot in my integrated. It's not even close. The Noble pot isn't bad by any means. When compared to the TVC. It sounds out of focus and instruments and voices suffer from slight loss of depth and separation. Also the sound doesn't flow into the room as with the TVC.
What TVC have you tried in your system Jsadurni?

Another owner of this unit. Just posted a small review on another site yesterday of the Promitheus against the Luminous Audio passive Axiom noble pot/shunt and a AVI active preamp. Again the little unit came out on top in his system as well. I think the AVI is a $2800 active preamp. So if you only consider cost as premium sound ..you maybe in for a surprise. ;-)

I may try to compare it against a Bryston BP6 in a few days. From memory of hearing the Bryston active last week..it doesn't stand a chance.LOL
