Headphones arrived very quickly in exactly the condition described. Thank you for a perfectly seamless transaction!

I was honestly expecting more for a NIB pair like this, but the market is down across the board.

You may have gotten a tired pair because I can confirm (having listened to hundreds of true Bad Boys vs VT-231) that the Bad Boy bass is FAR superior.  And neither the VT-231 nor the Bad Boys should have harsh, grainy, fatiguing treble.  They're actually known for outstanding treble, which is my...

One of the rarest 6SN7 variants is now on ebay in NIB condition: the 33S30B http://www.ebay.com/itm/2-pcs-NOS-NIB-33S30B-5692-6SN7GT-ECC33-Standard-Radio-/252379523567?   It'll be fun to see how crazy expensive this pair fetches.

Mechans invited me to take a look at this thread :)   Regarding the "Western Electric 6SN7GT," here's a short history lesson.  Western Electric, as we all know, is one of the great American tube manufacturers.  The interesting factoid that few people know is that WE opened up a low-key...

  edit: From what I've read, the R stands for "replacement" (not OEM issue).  The other letters/numbers represents year, quarter, and production but I don't know how to read it.  My 6SN7 and tube interests kinda stop in the 1950s :)

Sylvania codes are as follows: If you see six numbers (either in a row or in two pairs of three):  First three numbers will read 312, which is Sylvania's manufacturer code.  The next three numbers tell you the year and month.  The first digit of the three numbers is the last digit of the year. ...

Quote:   Ya, those are all definitely nice to have in any collection.  I've got the ECC33, 34, and 35.  I always wanted  NIB pair of QA2408 but couldn't find them, only a few singles that were mismatched.  Same with FIVRE and SICTE.  Most of the Euro 6SN7-kins are hard to find in the...

I've got four SS3S0 and to be honest, they're soooooo not worth their price.  They sound like a fuller body 5692 with a touch immediacy (not as laid back as the RCA or CBS).  But the price ... I wouldn't bother.  I got more of a kick finding generic "Standard brand" boxes for these Swede...

Thanks Cee Tee.  I'll take a look at both.  I don't know if I can afford running seven 6SN7s for the EC :P   Here's a pic of my main NOS/NIB 6SN7 collection.  It's about 20% of my NOS 6SN7 collection, but the tubes in this case are honestly holy grails and took forever to assemble...

Ok, I do have a question having been away for so long.  What are some current 6SN7-based headphone amps?   I think I want to dip my feet back into headphone waters.  I've used a bunch of Singlepowers (read bout Mikhail's sordid end), Cary 300SEI, Wheatfields, and Berning but I doubt any of these...

Wow.  I've been gone for almost a decade and this thread is still going! O.o   6SN7s are magical.  I think I should take a photo of my holy grail collection ^.^

No, the new ipod is terrible for runners. I've already encountered the sweat issue, but for me, the problem was temporary (the volume went back down to normal after a few days of drying out). But what bugs me most is the location of the new controls. A lot of runners prefer to have their cables...

Chinese aren't Asians? British, Germans, Dutch, French, and Italians aren't Europeans?

I don't see a UPC review. UPCs work differently then UO (more akin to what Shunyata employs), so it's unfair to extrapolate data from the UO measurements for the UPC. The reviewer of that article concluded the UO made a signficant audible difference/improvement. The empircal data shows little...

PS Audio's response is a bit disengenious. I'd love to hear his comments on PS Audio's UO (now called humbusters) or UPC, both of which are generate no detectable heat during operation and have no published specs that I'm aware of. I've owned two Power Plants. They are well built and have...

Problems with realjazzcat are numerous. He's been known to buy cheap tubes, goldplate their pins, and resell them as something they aren't. He will use "original boxes" as props: sometimes the boxes aren't included but are pictured in the auction to drive up the value, while other times the...

When you've got a target market value of $1,000 for your amp, cost certainly is some consideration. Depending on various factors, a manufacturer usually has to charge anywhere from three to eight times the cost of raw parts to turn a profit. That leaves very little in your budget for even $2...

I'm the last person in the world who wants to defend Shunyata's pricing. However, for starters, comparing Shunyata to Monster is ridiculous. It's not remotely the same (either in design or how they sound).

Yep. A properly designed conditioner should have similiar parts. Problem is, the power supply of most components aren't "properly designed" either because of lazy engineering or (more commonly) due to cost issues. I wouldn't expect any sub-$3,000 component to incorporate anything remotely...

Welly, I don't own the Shunyata, but it is one of the best sounding PLC on the market to my ears. I just reviewed the linked thread and am apalled by the ghastly misinformation in it.

Passive, transformerless power conditioning is the only way to go for me. Audio Magic, Shunyata, et. al.

Didn't mean to shoot the messanger Just wanted to collaborate data. Borrowed from tubeworld: Quote: 6DJ8 ELECTRICAL DATA: --------------- MAX RATINGS: ----------- Heater voltage 6.3V Heater current 365mA Max plate voltage (Ia=0) 550V Max operating plate voltage 130V * Max...

E88CC is the european designation for 6922. So, E88CC=6922. I'm using the early 1960s Siemens CCa in my Jotas. The strange thing is I find Tungsram most similiar to Siemens then any other 6DJ8-type tube.
