Quoteas far as i know, there's no other audio specific material like BHP avail...is there???? damping material designed for trannies???gooberdude,If you have a chance to get the Ebony wood (sold on ebay for knives handles) you will be surprised too. I have used them to lay on top of trannies of my amp and preamp and got good results.
Check Yamamoto PB-22 ebony base out. Really, really cheap. looks beautiful and usually works very well. You can use it svereal ways, 3 or 4. I have quite a few.http://www2.117.ne.jp/%7ey-s/PB-22-e.html

Thanks Tanjust what I was hoping for. I am about to buy various inexpensive wood cabinet knobs, wood knife planks, wood plugs made of various woods; cherry, ebony, oak and spruce to dig in and try lots of different tonewoods (maybe not the purist grade at first) with out spending a fortune just to see what they might do. I am also gonna try cork just for fun since someone uses it in iso blocks. just gonna play around with lots of options see what I can learn and maybe get lucky.On this same thought process seeing the Altman DAC on wood chassis and other gear and reading up on such it seems worth while.So this is a question I meant to ask a long time ago Does anyone know why the basic TVC's have metal tops and bottoms - was it an economics decision? or do they impart a better sound to the device? I got the impression the statement series would be all wood? If this is true I am guessing and only guessing a wood bottom might be a better choice for the basic and Ref TVCs? Or maybe the improvements are so small the expense over-road the improvements in the basic TVCs? Nick? Anyone been bold enough to try replacing the bottom steel with a wood plank they think would aid the presentation of music? (i know some have mounted the trannies on ebony blanks and so on)or even a large piece of BHP under the bottom plate with a selected wood under it covering the whole area of the metal plate?just wondering if the metal is not the ideal choice? Might some of us try some other alternatives.With all the wood being talked about and used in audio chassis's I hope its not a fad but a worthwhile effort.
As you can see from the pic above, there is a volume knob on the front of the unit. Don't be misled by that picture, this unit is not a true integrated. What this volume knob does is attenuate the incoming signal. This allows you to directly connect a source to the amplifier. Not a bad option for those who either a) don't have room for a separate preamp b) don't want to spend the extra money for a preamp c) don't want the coloration often associated with a preamp. Oh, the pot for the gain control is an Alps.
Thanks RayThat's exactly what I was hoping to hear I think- so off we all go and continue our ear research- the thing is ridiculously good without touching it- knowing we can squeeze more for small audio change is just great fun Again Nick congratulations on a fantastic piece of gear.maybe its just good luck and synergy but I am having none of the sonic sacrifices some have mentioned using strait to an amp and desiring the active pre.Below box are some of Scott Faller's (Enjoy the Music) comments on my amp:QuoteAs you can see from the pic above, there is a volume knob on the front of the unit.

Anyone else try to order some Black Hole Pad recently?I order June 19th...still apparently out of stock.Hi Gaara,I have a sheet sitting here. I can precut you some enough for all four sides of each transformer. PM me your address, and I'll see what I can do for you. Hey, someone helped me out, so I am just paying it forward. Glad to do it.The 6.25 by 22, 2 strips one on the top underside and one on the bottom in between the two transformers, don't know I have enough for you there. But covering the frames of the trafos and especially underside, will go a long way to make this baby sing.Ray Bronk

On a side note, does anyone know what happened to the C-Cores? Rollo talked alot about them and the statement line then Nic said to disregard what Rollo said...so I have no idea if these are still being made and when (if) to expect them.

Might some of us try some other alternatives.With all the wood being talked about and used in audio chassis's I hope its not a fad but a worthwhile effort.any metal is certainly to be avoided next to the unshielded trannies.brass sounds better than steel but still worse than wood - especially if it is the one with good acoustic behaviour, a quality spruce or maple. never tried ebony.promi's first units with a thin wooden bottom were prone to a transport damage. i've seen and heard one whose trannie was badly lose with a nasty crack in the wooden bottom.i would expect that a thicker wooden bottom would be a solution. we've made a full naked version of a double-C core dual mono TVC screwed directly into the oak platform, no lid, no sides, no output connectors - directly soldered to the trannies.if you have any possibilites to live with something like this in your room, you shouldn't think twice.steel lid parts congest the sound of promi, IMHO.
Hi, Yeah, the possibilities of using wood aren't bad, but you then have to do some routing to get it to match up with the rest of the TVC. There's also the painting or whatever the process that Nick uses. You could probably redo the box and veneer it with a different color. Posibilities are endless here. .Ray

Raymy point is that once you throw the steel top & bottom, you should find yourself a decent wooden board and screw the trannies directly into in, leaving everything open. just make a front side so you can install your volume switchers. if you are confident in your selection of ICs, just solder them direct at the inputs/ouputs of the trannies.if worried about dust & dirt, make yourself an acrylic cover you can simple move everytime you plan to use the TVC.i don't know what nicholas uses to varnish wood, is it some acoustic treatment or just a sealer/colour.it should be either done properly, with a top quality varnish aimed for instruments that resonate such as violin or guitar, or it should be left without anything. many modern coats based on plastic are not any beneficial to the sound.it doesn't have to be hyped and expensive C37. there are other, cheaper manufacturers of good wood treatments for the instruments that don't cost a fortune and do a practically similar job. google, you'll find them.
