Passive Preamps w/ Transformer Volume Control


Anyone have first-hand experience with any of these?

I'm looking at passive TVC's from Music First Audio, Sonic Euphoria, etc. Any others out there I should be aware of?

Will be hooking up to Threshold SA/4e or SA/3.9e. Currently, they are both set up directly to CD players via variable out.

TIA

Jfd01,

Thanks, but not sure I like this. I have to wonder about the quality of the cable coming from the attenuator module, especially as compared to my other interconnects, which didn't come cheaply to me and which I enjoy quite a bit.
Clio99, yes of course, you might be right, and I haven't compared this little piece of cable with other cables so I can't say that it couldn't be improved upon; so far I haven't found any fault to it. However, as I mentioned in the previous post, there is an additional RCA output on top of the module, if one doesn't want to use the cable that's already there. I haven't used that output yet, but will try to do it before I send the unit back.
By the way, on the same subject, John wrote me the following:
"The 2nd output on the module is there to address EXACTLY this concern. I ran into this years ago with my old Bent Units. On the new TAP the main switch box/controller will have a dedicated separate and buffered (to take it out of the signal path) subwoofer output. The 2nd output on the module is there in case you want to use a particular cable from module to amp. I do find it kinda funny in a way - since the cable is shorter than the internal wiring in other pre-amps (it's only about 5 inches long - no jokes please......) and really in essense that internal wiring that would be inside - but you see it. It is actually a very custom cable I make up by hand - its a weave of OCC copper around a center core then insulated with natural cotton - very decent and more involved than internal wiring in any pre-amp I have seen!"
Cheers, Joel
Hmmmm...I guess a picture is worth a thousand words in this case. I can't picture what this might look like, but it sounds as if I have two choices: use the pigtails or add another set of ICs (my preference) in the chain.
Thanks for the clarification Edwyun.
In fact, I'm using a S&B passive. I prefer this to a ladder type resistor based unit -- which, OTOH is cheap to make (the S&B TVC is expensive); Both of the above where better than the basic rotary switch equivalent; I preferred relay switching than the mechanical, rotary, counterpart.
I have a Django TVC with amorphous core transformers that I would sell if you are interested.
