I had a nice day with Purk and got to recalibrate my ears a bit with his BHSE, DIY T2, Aristaeus, Carbon, and Mjolnir KGSShv mini on 009 and he90. Yggy source; Holland brown-base EL34 xf4/xf5 tubes on the BHSE.
The BHSE/009 really impressed me this time, more than prior listens with a NAD M51 source. The Yggy is a
great match here. The BHSE and the T2 are a clear cut above the other amps. It's better than any of the amps I own. Yes, the DIY T2 is still better than BHSE -- it's always the best amp, and anyone who says otherwise obviously hears very differently than me.
The 009 and he90 are both insanely good on the T2 -- and honestly not that far from each other. Just amazingly perfect in all respects (I'd probably pick 009 in a toss-up there, because I love that headphone so much). The 009 w/ BHSE + Holland EL34 and he90 w/ aristaeus are just below that (I didn't try he90 on BHSE) -- but of those 2, I prefer 009 w/ BHSE. From there, the 009/Carbon (i.e. what I have) is next best. Very excellent. I would place my DIY hev90 balanced w/009 on this level, though I often prefer the latter for its gorgeous mids & tone w/ Mazda silver plate 12ax7. The 009 w/ KGSShv mini and 009 w/ Aristeaus are below that. They lose a good deal compared to the above (better) pairings. But the 009/mini is actually quite good, excellent dynamics & detail -- it's just a bit shouty in the upper mids, which will get fatiguing over longer listening sessions.
Spritzer can rant about how crappy my particular Carbon build is; fine. I think it's quite nice. But the fact is it still sounds a good deal better than
any KGSShv build I've heard, including 3 minis from him. And the Head-amp BHSE with these particular Holland tubes sounds a good deal better than my Carbon. And the DIY T2 is better yet (no superior T2 examples from Mjolnir audio here).
If Spritzer's predications that BHSE owners will be selling them en-masse for his Carbons is true, then
good! Can't wait to bite on them BHSE ads -- no build wait!
