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

I am familiar with Bent. I believe Stevens & Billington (which owns Music First Audio aka MFA) provides the trannies for most TVC's including the ones for Bent.

That's just it, it difficult to find places/people who have actually auditioned this stuff. I am aware of the CI Audio's PLC-1 but I believe that still uses a resistor potentiometer.

As between a resistor-based passive preamp and a TVC, are there any benefits of the former over the latter. From what I've heard and read, the answer is no. Any thoughts?

The thresholds are definitely up to the task, as I've only used them directly connected to one input source without any preamp.

However, as I said before, I've been restricted to using CD players all of these years with a variable out.

IMO, go with the TVC.

Bent's new passive preamp will be using specially configured Intact Audio (Dave Slagle) autoformers. MFA/S&B cut John and other resellers off a while back. You can read the details by linking to the Audio Circle forum of the Bent website.
