I have my equipment in one room and my listening environment/chair in another. It's a good 40 foot run.

I already have high quality (Audioquest) RCA run in an under floor conduit from the equipment room to my chair.

My problem is that now that I have a Decware Taboo Mk3 headphone amp that sounds best via its four pin balanced connectors out to my new balanced Hk1000 and balanced Sennheiser 800s

Anyone here know where I could find someone who already has, or could make both a:
 

• Four pin male headphone (which would plug into my headphone amp) at one end and dual female RCA at the other end (which would connect to my conduit run), and
• Four pin female headphone (which my headphones would plug into) at one end and dual female RCA at the other end.

Thanks.

I also found the mullard gz30 a really good rectifier nice euphoric.

It is a great one! Underrated!

It works well particularly on csp2+ because I even heard it was voiced for 5y3 type tubes.  But on the taboo mkiii it is good too.  However it isn't as good on the wa22.  So here is an instance where tube design really affects the amp.

  Hello People,
 
Need some insights from actual MK3 owners who have tube-rolled. I recently purchased (process of delivery) a Decware Taboo MKIII amp for my LCD3. I had heard the music from similar setup and couldn't get the experience out from my head. Lusted for it and finally made the plunge.
 
However, the setup had rectifier tubes that were not part of the original MkIII. I cannot remember the brand. I searched this thread for rectifier tube alternatives but after going through 50+ pages of posts, I feel frustrated that I couldn’t get anywhere much.
 
If someone can list out some good alternatives or point me in the right direction, I would appreciate it a lot. Any good suggestions on the output and signal tubes are also welcome
 
FYI, the type of tubes on the Decware MK3 are –
Rectification       5Y3GT / 5U4 / 5AR4 tube rectification
Output tubes       SV83 or EL84 / 6BQ5
Signal tube         6922 / 6N1P
 
Thanks….

 
Hi, FYI I just put up on classifieds New matched pairs of Svetlana Tubes SV83.  I had bought in bulk and am selling some spare  pairs.  These are rare because no longer manufactured.  These are the best sounding power tubes I have heard for my Taboo.

Folks,

I have finally found the best combination of tubes for my MKIII.

Signal = Amperex pinched waist D-getter 6922
Output = Matched pair cryod SV83
Rectifier = Western Electric 422a

Happy listening days ahead!

I bet I would agree.  The 422a is excellent -layers of sound.  The 274b great too.  The Svetlana SV83 as well- tops.  Do not have the pinched waist though have heard good things.  Is yours from the US?
 
The metal gz32 is very holographic for a really nice different sound.

Where can purchase cryod SV83s?

I'm selling non-cryoed matched Svetlana SV83s pairs.  But do you know if they will cryo tubes for you?

Those are 6P15P made in the Voshkod plant in Russia.  $32 a tube?  I think it's a $15 tube that's being marked up considerably because it is cryoed but not even matched.  I have 6p14p-ev from this seller  http://www.ebay.com/itm/251932757494?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT .  They are some of the better kinds of either 6p14p or 6p15p tubes I have heard.  They are from the Reflector plant. 
 
But I wonder if you can tell a difference between those do you have other power tubes?  I've had other 6p15p and 6p15p-ev (military spec longer life) tubes and they have a warmer color to them.  But the Svetlana SV83 are not like any of them they are transparent but warm and really seem to enhance the hazen grid mod.  Anyway, I don't feel like spending over $64 to find out but I might ....

 
I found this: Going on anode (plate) dissipation data, the 6P14P and its variants are quoted at 14W (300-400V), whereas the SV83 and its variants are quoted at 12W (330V) dissipation. 6BQ5 (EL84) is rated at 12W (300V) and 7189 also at 12W (400V) for comparisons' sake.

The ones I got are matched. You need to let them know that you want a matched pair when you order and there is no extra charge for it. Compared to the original power tubes that came stock with my MKIII, these cryoed pair, to me sounds more meatier.

That's what I thought. The 6n15p are more lush sounding than the 6n14 but the latter are more transparent and ring clearer like a bell. I think the Svetlana sv83 are in between.

 

[jhljhl]

I think I remember Steve from decware said that I could use a 6sn7 adapter for the MKIII.  I tried a regular ge 6sn7.  I highly recommend it.  It opens up the sound stage quite a bit and a more holographic effect.

 

[jhljhl]

Not many decware users here. But wanted to note that the decware taboo mkIII with a csp2+ drives the hd650 very nicely - lifting the "veil" some call it.  It sounds great with an otl amp like the csp2+ alone but used in conjunction through the mkIII - it has more dynamic grip and depth - using a mullardz gz32 and a newly acquired white labeled pq amperex 6922 d-getter.  The csp2+ otl amp there is transparency and overall smoothness but the imaging is really increased through the mkIII.
 
I don't see much written about the MKIII with the hd650.  The hd800 with the CSP2+ and MKIII is also just as nice.  I have not read a description of it but there is more power, depth - imaging, and warmth with the combination.  The sound stage is not as wide as on a WA22 but there is good width and depth where it does not sound so expansive which can be not called for with some music on the hd800.  This comes in with vocals arias, solo instruments, and some classic rock.

Upgraded my input tube to a 'Reflektor Holy Grail '75 6N23P SWGP Silver Shields'
from this 6922 tube review http://www.head-fi.org/t/761078/6922-tube-review-17-top-6922-6n23p-e88cc-cca-7308-e188cc-tubes
Details and clarity was multiplied by 2 times. Also replaced the stock .315 ma fuse with a Hi-Fi tuning supreme fuse for that last 1-2% of audio nirvana boost.
I'm done tweaking the Taboo, I don't think it can get better than this.
