I just received (Shipped from AliExpres - China) a (supposed) matched set of EL34. I am testing them now (to determine how I built the 2 "matched" pairs) and will do 2 days of burning before I compare them to the Stock Mullard that were shipped with my BHSE.

If I’m not mistaken, didn’t you purchase a quad of 1950s vintage NOS Philips metal base EL34s a while back? Wondering if you still have them and what’s your opinion of them after using them for an extended period. Thx!

As a matter of fact I retourned the Philips Métal base to the vendor. I was not happy with the sound, bass were inflatedn and not natural. May be the tubes were defective ??

Thanks for the answer!

So, I regularly trawl ebay for anything stax related. A while ago I found this item: "Pawel Acoustic hp-3 Pro Monitor Headphone processor / amplifier for Stax". Does anyone know more about it? I'm just curious because I've never heard of it before.

 

[Jones Bob]

A link might help.

Pawel Acoustics HP-3. Looks like they aren't making/selling them at this time, but have some kind of cross-link box, maybe similar to the old Stax ED-1 diffuse field equalizer?

The related products from Pawel Acoustic have been discussed around here before, try googling for "site:https://www.head-fi.org/threads pawel hp1". Pawel still build a later model without the STAX amp: http://www.pawel-acoustics.ch/products.html They don't provide anything but a picture for the device for sale on ebay http://www.pawel-acoustics.ch/discontinued_products.html

More modern products that claim to achieve similar things would be the Smyth A8 or A16, Creative Super-XFI or OOYH. Minus the STAX amp, of course. The A8 used to be sold bundled with a STAX SRS-2170.

After 20 hours of warm-up of the EL34, the values have evolved a bit. I will apair 1 with 3 and 2 with 4 to built the 2 pairs.

This evening I will stop the testing and insert the new tubes into the BHSE...

You should buy 2 additional tubes

New PSVANE installed now. Very first listening impressions are good: quite dynamic new life for my BHSE.

And how about XF2 Quad ? Have you tried it yet

No. Sorry...

The T1 & T1S and T1W are a better match to Lambdas design. May not work as good with the SR009 though.

well, as usual YMMV and I respect your opinion, but I do find a perfectly reconditioned (all electrolytics changed by Stax Japan) T1W with Clear Top tubes to work incrediby well with my 009. if I compare to my GG (SED =C= EL34 or JJ 6CA7) the only thngs missing are a wider soundstage (much better the GG one), a bit of extension and "air" in the highs (GG is more "open" and extended), and a general less "linearity" (the T1W is more "romantic" and relaxed while GG is more "hifi" and dynamic). but I must be honest, I could have lived with full pleasure and no regrets with the T1W if I was in a budget constraint.

of course, the above depends on my taste (I do prefer a very neutral sound with just a touch of warmth, very dynamic and transparent), the music I like to listen to (mainly acoustic jazz, trip hop and some prog) and the volume I like to listen to (low to mid level, never to high volume)

I'm at my wits end with the SR-007A; despite my ears being quite small my left ear touches the driver and the headphone are too uncomfortable for regular use. Does anyone know of a method to make the earpads deeper so that my left ear doesn't touch the inner part of the SR-007A? The replacement ear pads seem to be made for both the SR-007II and SR-007A.

I know this topic has been raised over and over again, sorry.
If I want to drive an SR-009 (not 'S') properly (moderate levels), will the SRM-007tII be adequate? If not, which (non-DIY) headamp will drive it properly for a ~$1500 budget?
Thanks!
