more handwaving, please...do continue🙄
spouting extreme nonsense like the above discredits your entire opinion for me i'm afraid, might want to temper it if you want it to be more believable and sound like something other than extreme personal bias and chest thumping.

silent screamer, like I said PM nattonrice if you cant wait. Hes in Sydney too, you might even be able to arrange a test.

I looked through his build photos and he made comments that his copy of the wire PCB was inferior to Owens. Bit reluctant to settle for anything less than the best the design can be, but I am still considering it.
I never say anything unconfirmed, I am sorry for you unable to compare to what's the best on the market, I did, also to LME, but you probably need some other guys to tell you later
SS,
If you want the lowest THD from an amp, I don't believe Aspen will help. It is a low negative global feedback ratio, so THD is quite high, around 0.05%. If you want the lowest THD, buy a brand new Spectral.
Cheers,
Hugh

Donkey only praises his own tail. 😀😀😀
That goes for you too qusp. 😀😀😀
I said I'd "made a poor man's interpretation".
When one has blatantly ripped off another man's idea I find it pays to be humble 😱
Actually I think we only ever hooked up 2 channels of the bridged AA to the subs that day mate, so it's not really a comparison at all.
Just to avoid people reading between the lines and taking the above the wrong way, I've got not problems at all with my aussie amps (nxv203 with 3channels in each 'module' 1 x 100W + 2 ch bridged for 300W for subwoofer). The aussie amp I have tops out at 100W. Basically, I needed a few extra channels of amps to go active and 2 x LME49830 + 2 x LME49600 based monoblocks all in one enclosure suited me from a neatness perspective as much as anything else. The Wire and the Aussie Amps are both very good designs, there is a few things Owen's able to do with his design because he has access to a VERY good measurement system.
The Wire amps have more comprehensive measurements, maybe slightly better, depends on the configuration chosen since they do SE, BAL, DC or AC coupled etc, but I've not done any side by side comparison. The AA vs The Wire Lateral Fet amplifier comparison is a hard one though, they have a very different input stage.
As a bonus I now get closer to 180W into 8R for L/R midbass from the LME49830. So a bit more headroom plus monoblock supplies that have headroom to burn too!! Since my AA amp has one PSU that is powering 2 x nxv203 I'm sure I'm putting a bit of demand on the power supply side, so I'm moving the 2x100W channels to power a higher efficiency active centre.
At some point after I have speakers built I might do a comparison, but that won't be until later in the year, I've got parts ordered for speakers but the CNC design isn't completed yet and at best I'm not expecting them to be in Bris for a few months. My B&W speakers are sold now so it'll be a happy day when the new ones arrive!!

I to have gone down the route of making my own PCB based upon opc's LPUHP design. Echoing nattonrice, being humble about it is good, as is making no untested claims about performance. One hopes that it would be a match for Owens design, but without full testing???
Hope you can find just the right amp for your needs, hopefully Owen wont be much longer with the new version of the (LP)UHP amp 🙂

In short, I think nattonrice's PCBs would be a bloody great option for the HF transducer if The Wire LPUHP re-release is not available. The new version Owen has planned is an improvement over his last LPUHP too, I still believe it will be worth the wait, though I understand the frustration of waiting without a known availability date. Owen has always operated this way, he will not make a promise that he cannot keep so won't speculate when there are still future hurdles that he has to clear that may change the dates he's able to offer them.
If it was me, I'd talk to Aussie Amps (Anthony Holton) or Aspen (Hugh Dean) for the mids, you'll want a bit more current to feed those and there has been no mention of a high powered amp from Owen, though one of the improvements will be a modest increase in power, not enough for mids though, IMO.

Thanks guys I am currently teeing up a demo with nattonrice to see if they are what I am chasing. I have emailed Anthony but yet to hear back, I might also look at the Aspen if I don't go Class D for the mids.
hey about yours, are the inputs floating, grounded, or with signal when you are getting that much offset? with such a wide bandwidth DC coupled amp, leakage as well as stray noise pickup could easily cause that much, or a small amount of motorboating depending on your care with input and output wiring.
the LPUHP is not my design, I had nothing at all to do with its design, I simply built some from Owen's GB PCB's and knew nattonrice had a diy facsimile for sale.
Silent screamer and I have been in contact about the possibility of using the LPUHP for his system sporadically for well over 6 months. He has been waiting for Owen to have his commercial version ready. it is as yet unavailable in any form, from anyone, least of all me, unless you make it yourself, so what exactly am I praising about 'my tail'?
that is why I told Lazycat if he wanted a c0ck-fight, he had the wrong guy...
I mentioned that he could buy Tom's version of the amp, Tom is a friend of mine and he lives in Sydney, as does silent screamer, which makes for the very rare possibility (in this game) of trying before buying. I gain nothing from this transaction not even ego ...
best to know what you are talking about before such comments wouldnt you agree? doesnt even seem like you read the first post, or any of my posts in full, yet you formed an 'opinion'

So you would need fully assembled modules, OK. I think it is possible to be done by some forum member, couple Australian friends will set them up, maybe asking them is a nice way to do it. 😉
I am sure you would be pleased with resolution and transparency of mids and highs presented by VSSA.
I thought analog signals had infinite resolution so wouldn't matter what analog amplifier you used?
Yes, they have all the same starting potentials on paper, in reality completely different story.
I test a lot in real systems and compare, evaluate, have friends beside to make consensus on opinions, the results are verifiable. Last week we had one of those tests ... read more in VSSA thread. 😉

I was just being the devils advocate!
Soon find out I invited a friend over on Saturday, and he is bring over his AA so we can get a side by side comparison going. I think it is the previous series, but close enough for reference purposes.
