Questyle CMA800 Current Mode amp - Page 35

post #511 of 596

Has anyone had the opportunity to do a critical "side by side" comparison of the Headamp GS-X MkII vs Questyle CMA800R (either SE or dual mono) using the HD800 phones?    I presently have one CMA800R and like it a lot with the HD800, but I'm leaning toward going balanced and at the same time acquiring a truly "end-game" amp for my system.    As good as the CMA800R is, I keep thinking about pulling the trigger for a GS-X MKII (despite the long wait).    From the scattered comments I've seen on various Head-Fi forums, I have the impression that the GS-X MKII is considered by many to be at the very top of the best SS amps for the HD800s.    At this point I'm not inclined toward buying another CMA800R to use for dual mono operation unless this combination is significantly better than a GS-X.

I haven't heard a GS-X in a while, and it was the original rather than the MkII. So I can't help there. I will say the main benefit of adding another CMA800R to the mix is with other headphones, more so than with HD800.

 

My full review is coming in the next week or so but to summarize - dual CMA800R really brings the LCD-3 to another level, and also sounds exceptional with HE-6 and HE-500. It makes a difference with HD800 but the improvement is nowhere near as drastic. I think just one of them already sounds so good with HD800 that maybe there just isn't as much room to improve.

Very very curious to read this. I just posted up my review of the Nuforce HA-200 monos earlier today.

Today I made the purchase, finally! :D Now it's just the waiting part....

post #515 of 596

In case you haven't seen it, my review of the Questyle CAS192D is up. I know some people were waiting for that, so HERE it is.

Got it in today! First impressions so far is that is a very very nice amp and a great match for HD800, no harhsness whatsoever. Got to spend more time with it before I say anything more, but I really like it so far!

Any impressions out there on using these as monoblocks yet?

Mine is all written up, just need to snap a few more pics and I'll have it posted. That could be tomorrow or next week depending on how much I procrastinate....

Looking forward to it! Tell me it's 5x better than the Nuforce monos :tongue:

It's terrible! No seriously, you'll see.... it sounds better across the board but some headphones benefit more than others.

I have the NuForce monos in and I do like what I hear. Questyle is better for sure, but of course not 5x better. It never really scales that way does it?

post #522 of 596

A linear scale would be awesome. We're gonna set 100% fidelity at $100 just to keep it simple alright? :tongue:

@project86 Do you know if the input impedance of 47K ohms changes when going dual mono? I wonder how well the dual mono setup would work with a tube preamp like the Bottlehead BeePre, seeing how you pretty much need a preamp when going dual mono. Right now I'm using the Bottlehead Smash preamp with my single CMA800R and I find it improves the sound in refinement, imaging, and spacing. Notably less compressed or congested sounding.

post #524 of 596

At most it would be reduced by a factor of two. Probably not enough to be concerned about.

post #525 of 596

Hmm. After listening in a longer period and testing some more tracks I hear something graininess-ish things in the treble region. It sounds harsh and not real life like. Also I switched back just to test the Vali and it didn't have the digitus-like sound. It also seemed that the Vali had more bass slam, and from what I've read here that should not be the case with the CMA800R.

 

Is it that my gear (the x-sabre with laptop) are the problem? Has anyone else experienced this?
