The new Eddie Current 2A3x4

post #1 of 124
Thread Starter 

 

After a long eight month wait, here is a quick crummy picture of my new amplifier...the Eddie Current 2A3x4!

 

Four paralleled 2A3s with the famous Eddie Current high fequency AC filament heater, two 6C45pi interstage coupled driver tubes, and a 6D22s based power supply.  This bad boy outputs 6w per channel into 8ohm so you can use it with all your power hungry orthos as well as high efficiency speakers.

 

Enough about the specs, this amplifier has truly blown me away.  Here are a couple of early impressions on this amp

 

The soundstage is truly incredible.  With the HD800 I have never heard such a deep, layered, and expansive sound before. Craig says it is able to surpass the Balancing Act, which is no small feat when considering the BA's legendary status in this regard.

 

The most impressive thing so far is the tonal accuracy and resolution.  The 2A3x4 reveals the most natural presentation of musical instruments I have experienced.  By natural presentation, I mean you get to experience an instrument almost as if it were being played right beside you.  The attack, decay, and timbre of each note lets you hear all the nuances of the musicians technique.  Not only that, but it has revealed a ton of beautiful detail in recordings that I had previously written off as marginal.

 

Anyway, those are just a couple of brief things that have stood out to me so far.  I will be preparing a more detailed review after I get some more listening time. 

 

I got number 2 from the first run so they are still in the early stages of delivery.  Looking forward to hearing from other owners. I know there is a 2A3x4 that will be on show at the upcoming SF meet so hopefully others can join in as well!

Congrats Stapsy-can't wait for the full review! I feel you pain on the wait time-been about 14 months and counting on the Levi so far.

What dac are you using currently?

It's hard to tell from the pic, but the two OPTs on the back look enormous.  Are they C-core?  It's hard to tell.  I am just guessing that the two in the front are interstage transformers.  Is that correct?

Congratulation! Could we have more pics including the power supply please?

Yep those are the OPTs at the back and they  are enormous. ITs are at the front.  I will get some better pics soon.

 

 

 

Bourne, right now I am using the Anedio D2 but it is definitely in line for an upgrade.  I am still using the stock tubes, so by the time you get the upgraded trannies and upgraded tubes the Levi is going to be absolutely mind blowing.

I'm pretty sure the transformers are both Hammond's. No clue what kind of core.

I'll be getting one. I can't wait.

I see references here and there to C-core OPTs for this amp, but so far they all look like EI Cores.  Hammond doesn't make c-core transformers commercially.  What I am trying to find out is if anyone has been sold this amp with the claim it has C-core or double C-core OPTs.  If so, I would like to know what it looks like.  I'm simply curious.  If such OPts are used, one would expect a pretty substantial sonic improvement, based on my experience switching from EI  to double C-core OPTs with an AN UK 300B amp.

The older mkI version uses Electra-Print.

 

m2man - is that confirmed by Craig that mkIV uses Hammond OPTs?

Yes sir, all the production versions are using the Hammond OPT and IT.  I am fairly sure they were designed as per Craig specs and  I know that they were found to measure better than anything else that was tested besides Tango's, but the Tango's are unobtanium now.  If you don't mind doing some small modifications to the case work you could theoretically tranny roll to the Tango's or any other transformer.  There may also be some versions of the 2A3x4 floating around that use the Electra-print partial silver transformers.  Keep in mind that most of the reason for the long lead time was finding suitable transformers.  A LOT of testing went into the decision to use the Hammond's.

 

As far as the C vs. EI cores I have no idea.  I am sure you could send an email to Craig and he would reply with an incredibly detailed/technical response that goes far beyond my understanding.

 

 

For anyone that is interested I am using the Sovtek 2A3s right now which sound very good.  I don't have any desire to change them at this point, though I will probably get an assortment of NOS 2A3s and EML mesh plates in the future to play around with.

Thanks for the inform Stapsy!

post #13 of 124

I picked up my 2A3 MkIV last weekend from Craig (serial number 1).  It's sounding pretty amazing with EML mesh plates.  My amp is slightly different than Stapsy's, as mine is using Electra Print C core output transformers instead of the Hammonds.  I heard someone else's 2A3 MkIV at the NorCal Head-Fi meet last weekend, might've been Stapsy's.  At any rate, the amp was connected to some home built speakers and it sounded pretty good.  I will be using my amp for headphones pretty much exclusively for the foreseeable future, but I may eventually get some speakers.

 

At any rate, when I get a chance I may post some impressions of the amp.  I'm not sure that I'm the best person in the world to "review" the amp, since I own the thing and therefor may not have an unbiased opinion.  Indeed, for that very reason I have never put much stock into equipment reviews, even from so-called neutral sources.

 

That said, I agree with Stapsy that the amp presents an excellent natural tonality and that the instrument separation and soundstage sound very realistic to me.  I have been primarily listening to the amp with a pair of Audeze LCD-XC cans, and because of the closed nature of the headphones, I think that the mids sound just a bit more hemmed in than they should be.  Indeed, when I listened to the open LCD-X and the closed LCD-XC side by side I found that I preferred the open X cans by far.  Nevertheless, I am in a position where I really need to use closed cans at home, and these are among the best that I've been able to find.  The headphones themselves were a revelation to me in terms of what can be achieved with closed headphones.  Paired with the EC amp has really been an amazing experience for me.  I am looking forward to years of musical bliss that this system engenders.

 

I'll post some pics up here when I get a chance.

Does the 2A3 MkIV play nice with the TH900? Thanks.

That's one of the big reasons I'm getting it. Should be great. Craig suggested it, though I'm not sure if he has those cans. Should be a little tubier than the BA and less so than the ZD.
