MuppetFace - do you like the ZDSE pairing with the TH900 over most other amps?
I'm wondering if you tried the TH900 with your Leben cs300xs? Interested in your impressions.

Thanks smily_headphones1.gif

The main issue I have with my Leben CS300XS is a persistent hum with certain headphones, and with the sensitivity of the TH900, it's too distracting for me. I've seen reports all over the place however, with some people saying they only have hum on a few specific headphones, and others saying they have absolutely no hum on anything (including IEMs...!). So maybe I'm just one of the ones who got a super-noisy amp? I've tried everything from tube rolling to power conditioners to taking it apart and checking for loose screws. No dice.

Posts like these make me happy as a soon-to-be owner of a ZDSE. I don't have the luxury to afford more than one flagship headphone, at least not for a very long time, and I'm already happy with having only a TH900 as it performs superbly in virtually all genres I throw at it. Yep, the ZDSE + TH900 is going to be my end-game headphons system, unless I win a lottery.

By all accounts it sure says alot about how good ZDSE sounds paired with the TH900, and I hear you not having the luxury to own more. This is why I'm looking at the BA or 2A3 over the ZDSE for it being single ended, leaving you no where to go if you ended up wanting to buy a balance headphone later on.

 

I'm also looking at Ray Samuels Dark Star solid state, however I've read low impedance phones are not really recommend for this amp. Can anyone back this up or debunk it?

I'd seriously recommend staying away from the Dark Star if you want to run sensitive and low impedance headphones. This is an amp that can destroy an HE-6 by overdriving it.

Thanks Muppet Face. I was really impressed by the BA that I heard once, if the ZD can match that (or even better it) i'm in. Handy, i was thinking of getting an HD800 as well.

Sorry, I don't mean to paint the ZDSE as outperforming the BA or anything like that. In most areas the BA is still a cut above, including its ability to extract the HD800's potential. However the ZDSE is no slouch with the HD800, and in the case with the TH900 I (and a few others) happen to prefer the ZDSE because of its very slight tonal luxuriousness. Not to say the ZDSE is overtly colored: it's still one of the most transparent amps I've heard, even more "solid state" than a lot of solid state amps; just relative to the other Eddie Current amps it has a bit of added luxury in its sound.

 

Kind of like the TH900 itself, it manages to be clear and open but still robust, both exacting and fun.

I still don't understand what this meansblink.gif

 

Anyway, what are some good SS amps to pair with the TH900?

There's a stereotypical way solid state amps are supposed to sound, and a stereotypical way tube amps are supposed to sound. People extrapolate this, and it sometimes results in the [erroneous] assumption that all or most of those types of amps sound a certain way. Only in actuality plenty of solid state amps sound the stereotypical way tube amps are supposed to sound, and plenty of tube amps sound the stereotypical way solid state amps are supposed to sound. It's a concept one finds in statistical analysis and experimental design: the difference within groups is greater than between groups.

 

To that end, Eddie Current tube amps sound more transparent, clean, fast, and resolving than a lot of solid state amps I've heard. That is what I mean by "even more solid state than a lot of solid state amps" more or less.

 

It wasn't my intention to get into some fruitless debate about it though. Just explaining what was meant by the comment.

The TH900 is forgiving enough to where it sounds pretty good on a lot of gear, even unamped. I think it sounds pretty good out of the UHA-6S. The Auditor / Phonitor works surprisingly well with it, and I didn't hear much in the way of background noise from recollection. The B22 is fine with the TH900 too, though the LAu prototype I heard was better.

 

I think the Burson Conductor is solid state? Driver8 seems to like it, but I don't know what he thinks of it with the TH900 specifically.

Oh no, I don't disagree or agree - don't matter much to me and was never meant to be a debate in the first place.  I just simple stated what I didn't understand.  I was just wondering what a SS amp sound like other than a SS amp.  That's all.. 

 

I hope the new GS-X will pair with these good.  Now I have the W3000anv and they sound really good on my Balanced M^3.  I rolled a few opams to get the sound I wanted for those ans the HD800s.

Whoa, definitely not bright for me. Of the three I had at the same time, B22 was brightest (and most detailed with widest soundstage), followed by ZD (Stock tubes), then the LF - granted the LF did have the Genelax Gold Lion matched quad in it which is famed for a smooth high end - they were not stock tubes. 

 

LF + TH900 is a nice dense and engaging sound. Lots of detail and loads of texture.

Conductor (or Soloist if you just want the amp part) -> TH900 is pretty good.  It has a bolder sound than ECBA -> TH900 while still maintaining good resolution and imaging; I don't feel like this source bottlenecks the TH900's as I kind of did with the earlier Burson all-in-one I had.  It has a denser image than my ECBA, but I wouldn't call it congested; the ECBA is just especially open (and significantly more expensive).  Bass is very clear and fast but its impact is harder than other TH900's setups I've used.  I could see some thinking it's excessive, although I haven't found it problematic.  I don't think I'd recommend it as someone's sole rig, though, for that reason.

 

Note on all Burson stuff: It burns in.  Iuno why as I typically don't believe in solid state burn-in, but my Conductor sounded a lot different the very first night I had it -- kind of bright and thin.  My old HA160-D had a similar phenomenon too.  These are differences I noticed very early on, though.  I wouldn't recommend keeping it for like 400 hours of use or something if someone were to buy one and not like it, more like a couple days of reasonable use.

The ZDSE stock tube is crap. Too bad you didn't do the comparison with a better driver tube, imo.

Completely agree. I could have tube rolled everything unto oblivion. I didn't have the money nor time to be able to do that. The ZD is something truly special and I surely wish I could have kept it.

I have to agree with you - unfortunately my Leben cs300xs also suffers from hum - I tried tube rolling as well to no avail.

Sonically I was not overly impressed with the pairing - which surprised me as I do like the Leben.

I could see them pairing poorly simply because of their sound signatures. I'll get to hear it for myself soon though. Still waiting for my Leben to come in. Hoping there's no hum on the HP out.
