Excellent review bro.
OK, since you guys have been so helpful with your tips I'd like to post a review of my JAN Sylvania 6922 tubes circa '73, that I purchased off Tube Depot a month ago.
Why do they warrant space on the 390 pages of part 2 of the rolling thread? Cause they're available easily, they're "fairly" inexpensive at $100 and they sound pretty good depending on your taste in music. More to come on that.
The headphones I'm using are HE-500's which are pretty flat, accurate, and are known to be a little forward sounding. I love them. Playing FLAC's through my Fiio X5 DAC hooked up to my Lyr. I'm playing some punk, some blues, and some metal while typing.
These are dark heavy tubes. Gothic. They mirror the decade in which they were born. Think Deep Purple, Rush, Led Zepplin or Black Sabbath (not that I like any of them).
They're full of bass. Not especially punchy, not particularly fast, in a good way. Kick drums take stage and bass guitars get their chance to shine amongst the band. They make my HE-500's sound like their wacky HE-400 brother on the bottom end.
The mid-range is no slouch. Guitars have a nice growl to them - distortion sounds cool, very analog. Old Black Keys sound really good.
The most pronounced feature is how far forward they are - it's like I'm plugged into the Marshall amp. There are no illusions what is in the left or right channel. The band has grabbed you firmly by the shoulders and plopped you down on the stage.
So if you like these qualities.... what's the problem? The top end is weak. It's partly why things sound too warm at times, the highs are recessed so far that top of the mids are just lost IMO. A shame because the cymbals are clean and vocals are warm too. The frustration happens when you want to mellow out and put in Rush - while the band is playing just for you, Geddy is pouting in the corner afraid to shriek.
So why do I like them at all? They're my favorite when I'm playing music with a lot of screaming or distortion. They naturally remove sibilance and highs that just hurt at a decent volume level - everything just rolls off the top. You're left with a tube that likes to blast guitars and drums. If you're into that sorta thing than this tube can sing. If you like electronic music on the side like I do, this tube is utter crud.
I reserve the right to pull this review in a heart beat when I get my 1962 Siemens CCa's and they manage to make a choir out of Converge or Pissed Jeans.
If you have a different tube reco for metal / punk, let me know!
Rob.
