Its good stuff,nice find!

I can post some impressions when i've had the chance to play with them a little..

If they sound good, I'll surely order more for back-up

I ran through the volume from silent up past normal listening volume and could not hear an imbalance. I have the GE408A's running right now with a LT1364 opamp and think it sounds great with my MS2i's.

Thanks, bigjim82, I've checked this site out but shipping rates to Europe (about $18) are a bit too high, IMO. There's nothing extremely wrong with my wallet (considering the crisis) but the price/quality factor is my sacred rule.

Although, I realize - the best 408As available in most cases are Americans, so they couldn't compete with Mullards price-wise.

Heey! Very much enjoying these:

408A Tube [408A] - $5.49 : Piexx Company, Computers & Electronics

After i ordered a set, they got a $5.49 -pricetag immediately. (I payed $1.49/tube). $18 shipping, but was worth it

I ordered four tubes. Since yesterday i've been matching them, and now have found a darn good sounding one! I hope the sound-signature remains close to this after burn-in. After 5hrs, they sound very dynamic/transparent. Not as close or sweet as WE408As, and lack a little soundstage compared. BUT the punch and detail they deliver is fantastic! Accurate but plentiful bass (WE's had not much to mention), while being tonally accurate. Best all-rounder so far in my collection (6J1's and WE408A's). They sound a little bright still, I'm hoping it would calm down a little in the treble section, while retaining it's detail.. This happened to the WE408A's, so why not here? Let's hope

Cans that I tested them with were AD2000's and sr325i's. Still amazed by the dynamics and transparency these tubes delivered. So good sounding with AD2000's that i've started reconsidering a purchase of an SS-amp for them..
Anyone else tried these yet? Would love to hear a reference by another headfier!
I'd like to add, that there's little noticeable hiss, nothing that would dominate over the noise my graphics card makes though..

Ok, back to burning these babies in. Roger out

Hey guys,

This is a pretty noob question, but as much as we all love sound, is it possible to purchase tubes that emit different colour light? Or glow at different brightness levels? Because I'm sure you all love to see those tubes glow

 

[TKvC-SainT]

Yes, in fact I was quite surprised to see my Sylvania Gold 408A the first time. They glow around the same brightness as my former WE408A, but with a more redish color, while WE408A were more yellowish. So both orange, but one to the brighter side, and one to the darker.

 

[bnuttz]

So I had this crazy idea about fitting two single channel HDAMs in this thing with extension leads and the appropriate adapter of course. However, looking at this post:

The Zero MOD Thread - 24/192 DAC/H/Amp - Page 12 - Head-Fi: Covering Headphones, Earphones and Portable Audio

It appears that the base is the same size as the dual unit, which may be a problem. Anybody have any single channels they could try out, or have any thoughts?

Back in the day we had these...

I've been using the GE 408A as well as the stock 6JI for a while now.

The 408A is nice, seems to bring out more detail, focus is around the mids/uppermids. I find it lacking bass punch though. Are all 408As like this (Sylvanias, WE)? The 6JI is pronouncedly more bass-friendly.

Can anyone describe the sound signature of the Mullard EF92s?

 

[electropop]

I found the difference between GE- and WE408's to be quite the opposite of marginal. GE's do have plenty more of punch in the bass section, more apparent details and sound more transparent (though not short of SS-amps). Where it loses to the WE's is soundstage, dimensionality and forwardness.

I like the GE's best now, at least with my AD2000's. The Stock 6J1's are just too muffled. They have bass, but are unable to control it

GE408's have punch, and are also more dynamic. Maybe having a lower noisefloor has something to do with this..

Have yet to tried the sylvanias though..

The Sylvania 408A's are amazing, I would say the WE 408A are not too shabby but the Sylvania is definitely in a league beyond the WE in both dynamics and soundstaging.

Hmm.. But the AD2000's need bass and i recall someone saying that the sylvanias are slightly shy on that matter.. I don't really like the WE's after the GE's. They sound dull and lack punch. I guess these phones really need an ss-amp to drive them..:/
Grado's are another story..

Thanks anyway..

daymn DOA..the LD II looks awesome!

I read that blue LEDs were actually built into the amp, i wonder why they ceased production of LEDs in tube sockets. I'd gladly pay another $10 or so for them to be installed. Unless they cost more, i have no idea..

Any idea if these would be a reasonable upgrade? http://www.head-fi.org/forums/f44/2-...-cv131-391493/
Looking for cheap options just to try out first

 

[HeatFan12]

I personally love those EF92s...I think it's a great buy....
