Eddie Current Balancing Act - Page 82

post #1216 of 1488
Thanks for the reply Marv, informative as always. It is fascinating that you sat on the estat throne and decided it wasn't to your liking. I suppose you're the first in that regard. Then again you are something of a renegade in this here audio kingdom, so if a particular someone was to go against the grain...

You say you miss the BA, but I also recall you saying the 800 ran askew of your preferred FR. Is it just the amp that you miss or a synergy with something specific?

I'm mesmerized by the Lamp > BA > HD800 combo, and find this to be the only setup that gives my estats a run for their money. That said I prefer my Dynahi with the bulk of my other headphones. Sadly the BA + Dynahi did much of nothing when I tried them with the LCD2/3. Those cans just hit their peak quickly and don't advance commensurate with equipment upgrades ime.

Did you own the Cooter amp? I tried to get him to build me a little something, but nothing doing. I've been building furniture as a hobby these last couple of years and boy would his amps look great on a custom walnut audio rack.

It's the amp that I miss, or actually any of Craig's SET amps with the high-frequency filament heater. I sold my BA to partially fund the T2DIY, and since then, I've been without one of Craig's amps until recently where I was able to snag a used ZD. If I still had the BA, I'd probably pair it with the TH900, AD2000, or even the HD800 again. I may end up getting one or more of those 'phones with the ZD and resort to minor EQ.

 

One thing I've come to realize is that I like the sound of SET and traditional dynamics (more than orthos, stats, etc.); although I'm keeping the Abyss.

 

The Cooter amp I am referring to was at the Bay Area meet three or four year ago. It was one of the most memorable things I've ever heard.

 

I asked Jason @ Schiit if they would put tubes in the Yggy. Supposedly Mike's head almost exploded. I think they toyed with the idea, but I don't think it's gonna happen. The Lamp definitely sounds interesting.

Does anyone here knows where to order KR PX4 online except tubeuse(they do not have them anymore), or someone has an extra pair of PX-4 for sale.

Did you check with Craig?
post #1220 of 1488

yea, but he no long offers PX-4.

I compared my SR-009/SRM-717 to my friend's EC 2A3mk4 and was blown away by the EC. The 009 with 717 amp feels a little like the music being pushed down your ears. Eddie current rig feels like you are in the middle of a live performance. Very 3d holographic soundstage with slightly better micro detail. I listened to the 009 rig with a track I knew then switched straight to the Eddie Current with the same song and the difference was immediate and big. Within 2 hours my Stax rig was up for sale.

 

I ordered the 2A3mk4 but had not paid the deposit as Craig is backed up. Someone contacted me (after seeing a posting of mine) and offered to sell me the Balancing Act. I could not justify the difference in price (over $1,500) and went for the BA. The version I bought was the 307A and I am using it with the HD800. I received it today and love the sound but would prefer more emphasis on the bass and mids. I know the 307a is meant to be very neutral. I have the Ken Rad 307a and TS 6SN7. I'm using a Merdian dac which I really like and has good body to the bass and mids. I have a USB to Spdif converter (Off Ramp 5) coming soon so can maybe do it through the software (J River) on the pc. Alternatively, getting the Moon Audio Black Dragon or Blue Dragon may be the way forward. I don't want to lose anything else in the way it sounds now and not sure if these ables will take away from the current sound - Just want a bass and mid bass tilt to be added. Your thoughts would really be appreciated.

RCA 5692 red glass: thicker sound - gotta take that or leave it - the good and/or bad

7N7 black triangle plates on adapter: laid back

 

Most TS are pretty neutral sounding in comparison to the above.

 

There were a few other tubes I had in mind, but I tried to keep away anything with even a hint of additional treble or possible treble sharpness.

 

Also what DAC and what headphones?

Thank you Purrin. I am using the HD800 and the Meridian 568 as a dac. I compared the Merdian to the Anedio D2 which is so highly rated, especially on Head-fi and the Merdian beats it in nearly every way. It had deeper, more textured bass, there was more body to the voices and the highs were better. The Anedio D2 gives more of an open sound.

 

Just looking into the RCA 5692 red base (I take it that is what you meant). Would I need an adapter? I don't want to take anything away from what I have now so maybe the Moon Audio Black Dragon and slight eq (if necessary) is the way to go.

I have been considering the TH900 to pair with my ECBA.  I am concerned, however, with tales of abrasive treble.  Can anyone comment on this?  I am EXTREMELY sensitive to glare, grain or etch (I like LCD2 v 1's and LCD3's).  My LCD3's don't seem to be the best fit with this amp and am considering changing 1 or the other.  I can't seem to come up with a good headphone to pair with the BA.

Yeah - red base. No adapter. The 5692 is essentially a hardened 6SN7. RCA gave it a different number because of its sturdier construction. I think it was meant for artillery analog computers or something that like that.

Depending on the tubes that you roll, you may be able to tame the effects of the treble irregularity (short of a sharp hard glare). The treble spike is always going to be there, but with the BA, I found it just tolerable. I eventually resorted to EQ to notch the treble and reduce the sub and low bass.

Congrats, did you implement the HD800 mod yet.  That might be an easy way to move towards the sound you are after.  I would at least try it before rolling tubes.

post #1227 of 1488

I got the Cardas Clear cable and that has given me what I am looking for.

 

In terms of rolling pre-amp tubes, does it make a difference if the tube is unbalanced e.g. 90%/70%?

I use a 30 band EQ which I set up with a frequency analyzer to completely flatten the response curve.  I then make small adjusts to a few frequencies to suit my own hearing anomalies.  The results are mind blowing. 

 

Each tube requires it's own adjustment on the EQ but once that is done the sound is not so different amongst tubes.  I like the 5692 a lot in my ECBA, but they are getting expensive.  I also like the JAN CHS 6SN7WGT which isn't too crazy priced -- YET.

I really like the sound of the Cardas Cables for the HD800. The stock HD800 cables are actually good quality, but they just don't go well with the HD800's characteristics.

post #1230 of 1488

I agree the Cardas cable was an improvement over the stock in every way. I am a cable skeptic, but the Cardas cable gave a bit more body and clarity to the system.  A slight loss of airiness which I believe was because the Cardas smoothed out the somewhat sibilant HD800 treble.  It was very much like going from stock to modded HD800.

 

It certainly falls into the final tweak category as the difference was subtle but noticeable.
