The Next Batch: EC/SS - (Eventual Impressions) - Page 3

damn this thing has peaked my interest. what's the power output at 33ohm? Is it even close to Dynahi in current?

The ECSS will put 3 watts into 32 ohms. Not sure about the dynahi possibly someone else will chime in.

It would seem highly unlikely that the EC/SS would be capable of Dynahi levels of current output. The Dynahi will put approx. 7Wrms into a 33ohm load where the stated output (as 909 said) is 3W and it is unclear whether or not that is a peak or rms measurement.

Please note that the fact that the EC/SS has lower power output than the Dynahi does not diminish it in the slightest bit, you don't need anywhere near the output power of the EC/SS, not to mention the Dynahi.

any comparison with dynahi/dynamite would be very helpful since I really miss my old Dynahi

I heard the EC/SS with the first opamp and the dynahi back-to-back about 6 months ago (sources: mod Denon 3910 and Apollo; cables: UR8s). Yet as a preface I think the dynahi is probably the best single-ended solid-state amp I’ve heard with the EC/SS coming a close second to my ear’s musical listening preference. The new AD811 opamp brings the EC/SS much closer in my estimation, but I think the dynahi would be superior—particularly with respect to, dynamics, imaging, instrument separation and soundstage (limited to my use w/ the HD650s). Both have what I perceive and describe as similar positive tube attributes with the EC/SS a bit more tube like. I would need to hear the dynahi and the new EC/SS (AD811) back-to-back, but I surmise I might still tilt my hat to the dynahi. Yet I can’t say it would be a done deal or that clean cut as before since the new EC/SS drives headphones in such a phenomenally musical way with warmth, energy, excitement, hyper revealing detail and extreme precise control. I didn't want to stop listening.

It should be noted, I’ve not heard the RS-1s on the dynahi and I believe the L3000s picked up some minor background noise even with the volume pot near supposedly inaudible listening levels, but I assume that could be fixed or minimized with an adjustment. Also, I preferred the HD650s over the K701s with the dynahi and Denon combo because the later headphone in that system touched on a sensitive I perceived as a bit piercing in the upper register. As far as I could tell today, the L3000s weren’t picking up anything on the EC/SS within safe listening levels without a source playing so I could test it.

I guess I am concerned with the holographic quality of EC/SS. Can I be fooled into believing I am not listening to cans? (Dynahi was almost there with HF1, although never with HD650) I will use the amp with HF1 and K701.

May I ask how much is the difference ? And if it's worth an upgrade ?

does anyone find it interesting that HEED is getting all the noob and EC is getting all the old timers.


EC/SS looks dual mono in design but does EC/SS have any global negative feedback? I can't tell from the layout.

I see 3 chips in the inside shot of newer version EC/SS. I know two of them are the AD811, but what is the thrid one at the front of the amp?

And it looks like the AD811s are just sitting in the chip socket? So does this mean one can try plugging in different opamps and experiment with sound? "Chip-rolling?"

The pic above is the previous version...




The pic above is the new version.

How to do 220V?

Here's the Eddie Current Website

Send Craig an email with your concern/question

He's made 220v amps before.

It seems you can just buy a wall wart power that takes in 220V and outputs 16Vac?

I would play it safe and check with Eddie Current first. Don't guess.
