All EAT Cool Valve ECC803S's are required to pass through rigorous testing to meet EAT's high standards. As a result of this selective process, all ECC803S's are matched to very similar specifications.
The Eat ECC88 Double Triode features a tight tolerance, vibration/shock-proof exterior, and is Cathode free from interface! The ECC88 Double Triode comes with a Cool Damper which offers a more controlled and deeper bass, a more open and detailed sound stage, and crisper and greater dynamic range.
Many people prefer the sound of EAT ECC88 triodes tubes for their "soft" saturation characteristics which can be quite pleasing to the ear!
Tight tolerances: In these tubes the tolerance of electrical ratings are reduced in comparision with standard tubes.
Vibration and shock proof: The tube withstands accelerationns of 2,5 g at 50Hz for lenghty periods and momentary shocks of 500g for short periods.
Cathode free from Interface: The cathode establishes no interface even in case where the heated tube is operated without plate current over lenghty periods.
Cool Dampers:
The Cool Damper is a radical new device from EAT - EuroAudioTeam (gotta love that name!). This beautifully crafted audio product offers much more than simply adding a new styling twist to your tubes by surrounding them in a fashionable outfit. It also brings exceptional acoustic performance and function to your system by delivering sound that redefines the tube damping category.
Carefully chosen materials for the Cool Dampers allow them to be used as truly effective vibration-consuming devices. This results in reduced distortion from the tube circuit, as well as vastly reducing the tendency of most vacuum tubes to act in a microphonic manner. Ridding your system of tube ringing is a big deal. Those pesky, ringing glass envelopes actually contribute a LOT of unwanted garbage to your sound. Cool Dampers are the cure. This translates into more controlled and deeper bass, a more open and detailed sound stage, and crisper and greater dynamic range.
Product Reviews:
"The sound is better than more affordable valves in my Astin Trew CD player, with less noise and more music." - Maarten van Casteren, TNT-Audio, September 2008
"When comparing the EAT valve to both other valves it always showed a clearly lower noise floor, enabling fine detail and acoustical cues to be heard more easily, and a cleaner and sweeter presentation overall. The whole spectrum seems to be extended a bit, with tighter and more tuneful bass and more air and detail at the top end. There's also an improvement in dynamics and vitality and a more natural and less 'rushed' presentation. All of this without losing the nice warmth and clarity typical for valves." - Maarten van Casteren, TNT-Audio, September 2008
"I have no problems at all recommending it." - Maarten van Casteren, TNT-Audio, September 2008
