Should the Jan be an obvious improvement?
I just purchased a 6922 jan sylvania tube and am quite disappointed. I cannot notice any improvement at all, actually, the new tube sounds worse than the original 6922EH. How real is time burn in/will this get better with time? I see nothing visually wrong with the tube, but I am new to this.
Should the Jan be an obvious improvement?
this is what I refer to when looking for my tubes ,it's pretty accurate and well written description of most of the tubes you can use on T1 and worth buying
I recently received E88CC/CCa Valvo Red Logo Röhre Valvola NOS 1965
and I'm positive I found what I was looking for ,it cost me arm and leg but oh boy this thing sounds sick ,pretty much all this

HD 600 and 650 weaknesses ;
LACKS DETAIL: The HD600 has a very smooth sound that can sometimes feel slow and slightly blurred. The HD600 is not the last word in terms of detail retrieval.
TOO SMOOTH: The HD650 can sometimes sound suffocated in its own warmth. It can sometimes sound as though it is attempting to lull you to sleep.
so I would look for a tube that can help you in that department..just my 2c
if you mean louder/more aggressive look for 6N23P-EV (EB) Reflector 1986 and older (double support type )
or Rocket but your sound stage will suffer a bit ,I really like what this tube have to offer ,pretty good bang for your buck

well folks, my T1 is in the house, up and running and burning in as we speak.
I have to say I am impressed. Not a huge OVERWHELMING bang but I never expected that considering my source is primarily XBOX Music downloads. what I did notice
wider, more holographic soundstage
The vocalist is nicely forward and I can literally hear them close to the mic (I cant describe it but it is better)
It can be a bit on the bright side but I think that can be attributed to the tube, burn-in, etc. Not overly but a tad. We WILL remedy that..LOL
So in my opinion, I think I gained 5 to 10%. Doesn't sound like a lot? It is huge. In the audiophile world, you can spend hundreds to thousands to get a 2% increase. For $159 to get even a 5% better in an already tuned system is awesome.
I used the supplied USB (seemed decent but may upgrade) and connected to my system using XLO HT Pro cables (no I did not spend $200 on them, they were a GIFT !!!)
Thank you all...now on to some basic tube rolling (damn..why couldn't they make it work with 12AU7's ..lol)
O_o That`s really weird that you can`t notice any improvement and find it even worse! ;S Green label JAN Sylvania 6922 should definitely be improvement over 6922EH ! First difference you should notice is better & more "foward" mids section + tighter bass. Soundstage is more or less same. Is this your first NOS tube? If you haven`t done analytical comparing before then maybe your ears aren`t used to finding differences. Also, what headphones are you using?
Btw, there are different label Sylvania`s, are you sure you got Green label JAN Sylvania 6922? Maybe yours is later production (worse sounding?) or it has reached to it`s "end of life"?
My tube is labeled like this: http://www.ebay.co.uk/itm/6922-Sylvania-Electronic-Tubes-/251024184077?pt=LH_DefaultDomain_0&hash=item3a7235130d
Except my tube has different number: 322 and next to it is EAD and there is also vertical number 7002 near the right side of labeling.
I'm using hd650s and this is my first time comparing tubes. I definitely am not used to comparing differences, but thought I would at least notice a few differences and definitely thought I would prefer the new tube, but I find myself wanting to put the old tube back in. I will use it for a week and see if the sound improves.
The big amp is a Velleman K4040 Tube power amp - 1 12AU7 phase spliter tube , 2 12AX7 input tubes, 8 6L6GC power tubes - 90wpc - All NOS early 60 tubes !
I am running Windows 8.1 with XBOX music pass for streaming
Senns HD280 Pro
No, wish I could have paid $109...paid $159 shipped via Amazon
Other notes - I am using a Marantz SR4023 as the pre and I have and have had multiple turntables (I am a vinyl nut) ..I have even built my own record cleaning machine
I use Polk Monitor 70 II's with a Polk sub . My main table is a ClearAudio Concept with Concept MC cart and a Phonomena II phono stage
I am a tube nut ! So the T1 really spoke to me...If you like tubes, this picture is my garage amp. I built a ss preamp from a kit ($22) built a box, attached it to an early 60's Motorola console amp, added some VU meters and have a little system....It sounds sweet !
