Hey Jaspal,What footers are you using now? I've been listening with the cheaper 2" mapleshade ones, sounds great.
a new element to the promitheus story made me thinking.... a TVC plus a tube active part together is now around $1000. if you add a price of a phono pre in case you may need it (as i do), you are coming to around $1600 or so (sorry i haven't checked a current price for a phono unit but remember it was around $500 ex-shipping).so, $1600 and 5 boxes in the house, plus 2 extra cables.... not sure this sounds inviting to me. thanks but no thanks. for similar money i would rather go for a full function single chasis (or separate supply) unit on a secondhand market. for example mine EAR 864 (not a TVC, but a decent valve pre with transformer output and MM/MC stage) was paid around $1400 for a mint, 1-year old piece, with excellent resale value.nick, if you read this, i really think you need to make a strategy for your business and some sort of business plan. idea of an active pre to complement TVC can be interesting to some people but not to everyone who bought a TVC. i think, if you are confident that a combo of a TVC and a tube active part is your definitive answer to the world of audio, you need to make 1 product out of that, to make an attractive chasis and good, ergonomic design. not all of us are natural born hi-fi tweakers and nerds, some of us like a simplicity and easy, plug'n'play products.you also need to think about the price and to see what cuts are possible - i think that with a $1,000 tag it definitely can't be as attractive as a $340 only TVC. i know you can always produce for a niche market, specialists' specalists, but i think you have a great talent and a good understadning of audio that you need to try to bring your products closer to more people than now, and to develop your business into something that will leave a greater impact on the hi-fi world.hope you will understand i am writing this because of my wish for your success to grow much more than now.
Hi. I've recently bought a pair of Promitheus TVC transx and wired them up myself, so I think I can help with gooberdude's question about rewiring them. Yes, the wires coming out of the transx are the actual trans wires, since each trans is wound with one continuous piece of wire, with the tappings coming out in loops. I don't see any great advantage to having separate volume knobs, but if you really want that it should be quite straightforward to move all the wires, including input and output connections, to a separate switch - but you would have to be very methodical and careful about getting all the connections right as there are a lot of quite delicate wires. Having wired my own, I certainly wouldn't like to do it for a living, and I would definitely agree with previous posters who say what a great bargain this TVC is! Incidentally, I'm really impressed with the sound of these transx. Compared with my previous resistor ladder attenuator I get better dynamics, plus the often-mentioned advantage of not losing the 'body' in the sound at lower volume levels. So thanks to all those who have posted in these many pages and persuaded me to go this route!
hey Jonners,thanks for the info. Can you post a pic of your TVC? Most of the pics posted so far have been of Nick's chassis.Its going to be a while B4 i get up the energy to take mine to a dual volume control, but good to know i don't have to buy a new unit and go through the break-in period again....I plan to keep these trannies for some time. My only reason for inquiring is that i've heard a dual, briefly, and do think that the stereo separation was noticeably better. i'm a sucker for that effect! can't help it.Nick, or anyone, would it make sense to add a vertical piece of copper or Mu metal inside the chassis of the Dual units to aid with the 'crosstalk' issue?? It would be as tall as the chassis and run from the front to back. This wouldn't be possible inside mine since the wires all come together at the single volume ctrl inthe center...but it seems like in the Dual units this wouldn't be hard to do.matt
Hi Gooberdude Did you compare the two TVC's side by side in the same system? The differences in crosstalk would be so tiny that I would be surprised if you could actually hear differences in stereo separation. If I play a signal through one channel of my TVC at max volume and listen only to what is leaking through through the other channel, the sound is only just audible with my ear right up to the speaker. Lots of people prefer the sound of vinyl, and the crosstalk in a vinyl cartridge would be orders of magnitude greater than we're talking about here. Maybe we should be trying to increase crosstalk? aa Ultimately, everything in the universe has got crosstalk with everything else, so let's have a beer and drink to it - makes the system sound better!
Ray is spot on, at least to my ears. The difference is not enough for me to go out and get a new TVC though, i had to work to get the one I have! But, it was noticeable...less congestion of the center image - it was spread out farther.If my trannies and chassis can be modded at a later date i may go that route though.I've heard a lot of people disliking preamps with Dual volume controls, citing that its difficult if not impossible to get both channels in sync with one another...these are not from TVC users, just posts on other forums (probably from active pre folks). So, i'm wondering if any Promi TVC owners with the dual controls have had issues? my guess is that due to the way the TVC handles volume increases in general, that the ill effects aren't present...just a guess though. If the preamp had 12db of gain it might be a difft story.matt
Would keeping the tranny wires away from the other trannie's wires reduce crosstalk?ie, would reducing crosstalk increase stereo separation?
I have ordered the ebony knobs for my TVC, solely because of their looks and the fact that it should be easier to see which source and volume level is selected. I very much doubt that they have any sonic effects at all, but time will tell.I don't quite get why some of you would add an active tubeamp to a system based around this TVC. Compared to my active, ss based preamp (a Hegel P4A) the TVC has more body and a "fatter" sound - kind of like some of the tube pre's I have listened to. If the system sounds thin/bright/lightweight with this TVC in place, I would rather start looking at speaker vs. room interactions or other components in the system. If your speakers (the single most important source of colorations and distortion!) are fairly balanced and the amp operates within its power envelope, what you basically hear is the system's source. I my view, it would be better to save up to a higher quality source which plays according to ones personal taste, than to add another source of coloration (the tube pre). Am I way out of line?

For the money, this is a winner.
