I was referring to the semiconductors...

Not going to happen, it's well and truly over. I doubt Toshiba or Sanyo would start re-production based on this industries piddley numbers. In fact I would have back-ups for the rarer parts, just in case, and insure your BHSE is able to continue past component life span or sudden failure.

The KGSSHV is the way to go, in many ways it's similar to the BHSE design, with exception for the last output stage.

Anyone using these? Heard of these?   http://www.elecdol.com/index.php/product-2/6ca7el34/

  The 007MK1s are a bitch load, the BHSE and T2 are the only amps I’ve heard that wake them up.

If subjective analysis through listening or the atheistic look wains, try some good old circuit research. At the end of the day the net value of your listening pleasure is all that counts. For me personally I like a well implemented design with strong technical sense. Any watch will tell the...

With hot plugging burning flesh is a good indicator that something is wrong.

  Why not? You have every right to your opinion, if we all agreed it would be pretty boring.   I wouldn’t be too quick to shot the messenger so to speak. For instance in my case I had a set of used tubes that did not sound good with the 009s, bought from ebay, I assume they were past their...

Using a lowly BuffaloIIISE DAC and getting excellent results from a BHSE and SR-009s, not at all bright or fatiguing. No regrets at all letting my SR-007MK1s go, I had the opportunity to compare the 009 and 007 together, there's wasn't a recording were I preferred the 007, across a wide range of...

I'm getting the EXTRA UNTESTED version, shippings loads quicker.

Phil95 would like to change his BHSE order, please make it in pink, because he's a big girls blouse.

Great idea! Justin can employ somebody to thread watch for all the questions needing answering. They'll have to bug Justin and waste time anyway for all the answers because they sure as hell they won't know and reply back here! You've got a real business head on you.

Alex,   Thank you for clearing this up that is re-asuring and great to know.   All the best, John

Alex,   Does the LL pose a safety concern? KG and Stax amps are voltage and current limited at the output jack. Do your designs follow a similar safety feature?   Cheers, John

I’m assuming your not happy and looks like you setting yourself up for another round of disappointment. Unless your going to audition equipment as this level with your own ears this thread will lead you nowhere fast. What would help is to explain your musical tastes, how loud and how long you...

  Yep. This is what its come too I’m afraid.

2C As the schematics stand the KGSSHV circuit functions flawlessly. A faulty KGSSHV amp is well, just a faulty amp. Refer to the schematics and fix it, after all this a DIY project, with no company or business front to take the blame.

No. The refinements have been functionality and sizing. The build can be customized though, from balls to the wall to a modest on-board version, depending how deep your pockets go.

I know the builder you’re referring too, I think... It was one of the earlier builds, from lil knights first boards runs. A lot has progressed since with reducing the risk of arching, better techniques, updated PCBs etc. The KGSSHV is always evolving, and none of them are identical whatsoever.

  As a rule if thumb I’d always put the circuit before the type of interconnect  

Nothing you haven’t seen before Corey, Just a straight up Buff IIISE with Trident regulators, LCDPS for VD and 2 x LCBPS for an IVY III plus Sumr transformers. I’m using the DACs internal volume controller, any future amp builds will not have analog pots, the digital control is the best...

  Perfectly said.

Indeed.

With a fully symetrical feedback scheme as well DC coupled, my DAC shines with balanced gear such as the BHSE, my latest DAC has no SE output, as I greatly prefer balanced as it's superior by principal. David, I believe the K01 uses 8 parallel/differential DAC circuits per channel, balanced is...
