I believe an active can do two things a passive can’t. My understanding is
1. An active and buffered-passive preamps with input/output buffering circuits can create a more immediate, livelier, robust presentation by lowering the output impedance and providing a constant output impedance for the power amp to work against.
· Have you tried using a buffer with a passive or a buffered-passive?
2. Active tube stages can create a sense of body, life and realism that I’ve yet to hear replicated in a solid (active or passive) design.
· Have you experimented with a tube source + passive vs a solid source + active tube stage?
Believe what your ears say - not hearsay.
Yes I've tried the SS buffer route using it before and after the TVC. It didn't make a difference either way I tried it in my system.
I've tried active tubes as the preamp. There's a certain thing tubes do that you can't get from the others.. this is true. At the same time I loss some of the transparency I've grown to love. I suppose it is a give and take.
That's probably why it is best to own one of each passive/tube and SS active. This way depending on the mood you get the sound you're looking for that day.
I've heard of audiophiles running an active tube preamp with their TVC.
I’m with you on the transparency thing. Although not practical and DANGEROUS, running my cdp direct “commando style” with no volume control device in the loop tells me exactly how transparent my system can be. So, adding something that degrades or paying more for something that retains more of what I already have seems so counterproductive.
Good golly that Promitheus thread over at audiocircle is long. I wasn’t aware of the active tubed stage product…looks interesting.
Yes that thread has developed a life of its own that's for sure!lol
FYI..I started that thread to see if anyone else had experienced the Promitheus..I had no idea it would have over 40 thousand views and 1500 posts.
