Stock Tube:
(K) Sounds wide w/ good bass..surprisingly to me...sounds GOOD. sweet vocals.
(Weird Fiches)hear crackling on Thoms voice on
(DArk Knight) I'm super curious how this track will sound with the good preamp tubes now. X2 struggling just a touch with the bass here..
(Rock Of Ages) Engaging ..is it the X2 that has widened the sound stage? Time to try the RAytheon tube.. : )
Up NExt..
NOS Raytheon 6SN7GT:
Now this tube sounds more natural compared to stock, mids more forward. (K)
My lord..the sound stage with the X2 cans
(4 minute warning)
I almost prefer the X2 with the darkness now...crap..
Love the echos here off my favorite track.. main vocals not entirely in control, but still enjoyable (Weird Fishes)
true test.. (Dark Knight Orchestra) bass struggles still and to be fair these are not high impedance cans, HD6XX hits this track to perfection, but we still have a few more tubes to roll..
(Rock Of Ages) Again vocals more up front (compared to stock) and Raytheon makes the stock feel dry sounding.. STILL ROLLING.. I WANT ROCK N ROLL....
Up NExt...
NOS Philco short bottle 6SN7GTB:
So I'm rolling these as to what i think is better than the former...and wow.. this tube from memory might have the most bass slam of all (k) curious as to how it will do with the (DArk Knight) not as wide as the RAytheon. I need another cup of coffee.. liking the vocals here ..almost HD6XX sounding
I listened to the whole track on that one..
(Four Minute Warning) yup...bass is there..this track is mixed wide so this tube and track are sounding special right now. lead vocal spot on.
(Weird Fishes) This might be my Radiohead tube..
(Dark Knight Orchestra) I don't know what kind of drums those are from the very beginning.. but this tube hit every one like a champ! I have tubes coming up that I feel separate the instruments better but this is an engaging tube. Almost forgot how much I liked it.
(Rock OF Ages) seems to have better imaging here compared to the Raytheon. some left right playing I didn't notice before. STILL ROLLING! Thinking I had more fun with the RAyteon though.. funny.
Up Next..
New Electro-Hermonix 6SN7EH:
(k) This tube clearly has it in the highs..crystal clear and extended. bass on par with the Philco.
(4 minute warning) Nice separation of instruments and vocals, it's inherited of this track, feels so right with this tube. listened to the whole track on this one.
(Weird Fishes) Tough deciding which tube I like with RAdiohead now..
Philco warm and wide vs Electros detailed and wide sound..like em both!
I get eaten by the worms....and weird fishes!!
(Perfect Darkness) sounds good
(Dark Knight Orchestra) If you like Hans Zimmer... THIS is the tube to get...mY God! BAss, width, tonality, instrument separation...and the violins...just sing!
Huge thanks to
@ggillies for sharing this magical track.. (Magic Bus Live- The Who) Sounds Superb here with this tube
(Rock Of Ages) Weird...still prefer the Raytheon on this track ;D
Up Next..
NOS Westinghouse 6SN7GTB:
(K) Sweet sounding, bass is there. and wide sound stage. This track has heavy bass tuning and this tube plays it well. vocal a little sharper than the Philco, Philco has the edge on vocals so far. Thats not saying this tube is bad at all, enjoying this.
(4 Minute Warning) First impression is that sound stage..very nice.
(Weird Fishes) This track can get busy so waiting to hear how this tube handles it.. so far..sounding really good. Descent job!
(Dark Knight) I'm surprised that this tube is handling this track so well, pumps out more volume, interesting. that sound stage!
(Magic Bus) Ok..for live recordings nothing has beaten this tube..wow..you go Westinghouse.
(Rock Of Ages) DUDE! Raytheon just lost its Rock title... THIS is the new Heir Of Rock.. so natural.. vocals stand out more, not so lost in the instruments here.. awww man..track is over..
Up NExt..
NOS RCA grey glassed 6SN7GT:
(K.) Vocals has a certain quality here.. not sure how to explain it.. bass pronounced in a great way.. I like bass
It's almost as the vocal here is floating above the instruments. nice separation.
(4 Minute Warning) Again.. the vocals..seem so natural. with the X2 cans..this might be my favorite on vocals. Sound stage just as good as the Westinghouse. wow..whole track..good sign!
(Weird Fishes/Arpeggi) Really diggin this tube about now.. Cymbals super clean on this track. Westinghouse might have the advantage when it gets busy, but by a hair!
(Perfect Darkness) I haven't commented much on this track..because all of these tubes (except stock) almost sounded identical o.O or I just got bored w the track? Anywho.. BAss, Vocal, and transparency all good.
(The Dark Knight Orchestra) Thunderous drums... horns loud and clear.... "I'm BAtman"...this tube does BAtman Justice.. (yeah I like Zimmerman, Vangelis too) I still can't believe this is a live recording....superb. I would have to A and B tubes to find the clear winner on this track..
(Magic Bus) This album has been said by many critics to be the best live
Rock album recording EVER. Everything sounds ...I hate to use these words... "real" and "natural" you can pick up some feed back now and then from the microphones used to record this,..cool, OH..almost forgot..the tube..
Sounding awesome as you'd expect by now..
(Rock Of Ages) Right off the bat..sounds like the Westinghouse.. busy track and recorded loud.. so when a tube can tame a track like this one..you know it's good. Westinghouse seems to have slightly more bass.
Up Next..
NEW Tung-Sol 6SN7GTB:
(K.) Don't know why new tubes get the bad wrap..this sounds pretty good, not as wide as the last two tubes rolled (Westinghouse, RCA) but certainly musical.
(4 Minute Warning) ok..I said not as wide..and as said before, this track has some width to it..and it's here. good vocal.
(Weird Fishes/Arpeggi) Liking the cymbals, Nice bass roll.. because these are "new" tubes I'm looking for something to critic here.. not finding it. Am I jaded?
(Perfect Darkness) ok here I can sense the width narrowing down again, sounds good still, vocal is great.
(The Dark Knight Orchestra) HAndling the bass drum kicks... a good start, some notes are louder than others as the two former tubes carried everything evenly, so it didn't "move" me like they did.
(Magic Bus) I like the width from the RCA and Westinghouse, the sound fills the entire spectrum left to right, here it's at spots. ..maybe that's what I'm listening too.. sounds good still.
(Rock Of Ages) vocal blends with instruments, nit picking, sounds kinda flat compared to the Westinghouse and RCA , way better than the Stock tube! and this track has all kinds of things going on in it.. recorded...loud.
More Notes:
The driver tube used for all the Philips/Mullard 6080, DAC used in Direct Mode from iFi Black Label (Double Burr Brown Dacs). Philips Fedelio X2 for the Headphones. All Tracks played from Tidal Master,PC. 15 to 20 mns warm up on all tubes.
Conclusion:
So I hope this didn't waste to much of your time with most of this really just blabbering thoughts.. I toke notes on this occasion, being my first real tube rolling day, with ALL my preamps.. and yes almost took me a day, got kids? And I didn't pick any winners... because it's all subjective..right?
