It's been a while that i wanted to write something about some 300B tubes that i bought last November (2004). Knowing you guys like pics i was waiting an opportunity to take good pics* before writing about these EAT 300B. EAT stand for "Euro Audio Team", a rather new company who introduced their 300B in the year 2003 or something (maybe 2002). I came accross this brand while looking for a pair to buy as 'back up' replacement for my Sophia/TJ. On a side note i'm amazed to discover a new 300B manufacturer almost every 6 months! 300Bs are strong and well alive, not a surprise when you know the unmatched qualities these tubes have to offer. Well i was planning to buy some Fullmusic 300B with 'st' shapped glass as they are from the same origin than the Sophia, the Chinese TJ factory, when i came accross these EAT tubes on a German website. They were looking good and at €550 a pair, hoped for them to be on the same class than the famous Alesa Vaic AVVT 300B Reference that unfortunately is no longer in production.
I had high doubt about buying those EAT tubes as i was able to find only one review and almost nothing on the web about this brand. I decided however to try them, based on the very modern look of the tube, especially the 'flat' plate that looked like AVVT tubes. At €550 a pair it was kinda risky, but hey, if we don't try we never know!.
I had first in my head/preamp the stock Electro Harmonix, not bad, gives you a good taste of the wonderfull 300B's capabilities like lot of 'air', true respect of the original harmonic's envelope and decay, with 300B a piano sound full and vibrant like the real thing period. One year later after reading a very good 300B shootout by Thorsten Loesch from enjoythemusic.com i decided to try the 300B Sophia 'mesh' plate, this one was much better than the EH, expanded 3D-like soundstage, gobs of details and a medium to die for, especially with voices, but maybe a little shy on the deep low end. (I knew AVVT tubes was supposed to do better in that matter).
Well, so i got those EAT 300B tubes in my head/preamp since 7 months now and all i can say it's maybe the most difficult piece of audio gear i had to talk about! Why? Because they just sound so damn good i still can't believe it! When you're too much dithyrambic about a product one can think the dude is not objective, but here, really, these tubes are so close to the ultimate perfection it's unreal. I have deep, controled, textured bass that can put the fastest transistor to shame. I have so much low level details that now i can say it's a truly holophonic experience, the 'breath', the size of the original recording or mix is now fully present. Dynamics that kill everything, effortless reproduction that grabs you and show you what breathtaking really means and most important IMO the legendary tonal accuracy, low level distortion 300B are famous for. Voices are so right and real it can make the most jaded, stone "heart-ed" audiophile cry...LOL. Really these tubes are so good words are useless, you need to listen seriously with a serious amp. This is the closest to perfection i ever heard from tube amplification and i'm using high-end tubes amps and pre since 1988.
But don't judge them before 25-50 hours or so. Brand new the sound was not very spectacular, i heard more details from the start respect to the Sophia, but the midrange was pretty thin, not wonderfully textured like with the Sophia. First i thought maybe i made a mistake with these tubes...but then after 10 hours the midrange began to get that density and texture 300B are famous for while maintaining an extremely good transparency and lot of air. Now that the EAT are fully 'burned-in' the Sophia, by comparison, sound distorted, uncontroled in the bass and have a very small (but pleasant) 2nd order harmonic distortion in the medium...that infamous 'tubey' sound!. The wonderfull thing with the EAT is that they don't sound "tube" or "transistor", they sound like your music is supposed to sound. The true mark of low harmonics distortion. These tubes are my 300B reference now, i don't need to look elsewhere and in fact they are so good and addictive that i'll need 8 pairs of these (yeah, 16 tubes!) for a crazy power amp (speaker) project i have...within 2 years.
A short resume: If you like a typical tubey sound and if absolute accuracy in the bottom end is not very important, these are maybe not for you, Sophia/TJ will do a great job for that and at half the price. If you're craving for near perfect tonal accuracy and real flat frequency response with a bass quality (fast and full) that can smoke most of the solid-state offering then go for it, these are a f...in' REFERENCE!
PS: You will notice i didn't talk about the highs, well i wanted to keep this short and while highs may be a little more extended with the EAT, most of the difference occurs in the bass and medium area of the spectrum.
PPS: I've just found another nice review from Positive Feedback. Glad i'm not the only one who's considering these tubes as a true Reference!
*Well having not yet my own digicam i'll update as soon as i can with cool pics.
