Questyle CMA800 Current Mode amp - Page 14

post #196 of 596

To me CMA800R is very transparent, therefore it'll show sound signature of the source quite clearly. So I guess it depends on the rest of your rig if DA8 is the right choice.

Yep, working on that now. I'll write up some thoughts when I'm done.

 

So far it seems like minor but worthwhile changes - character is the same, just a slight improvement with the R version. Which is impressive because the original is already so darn good.

I am considering replacing my WA7 with the CMA800R x 2.

 

The single CMA800R with DA8 is a fine combination. Slightly less detailed than Questyle's own CAS192 DAC, with a bit more musicality and "bounce" for lack of a better word. I enjoy the pairing very much. Can't yet say how dual CMA800R would improve on the situation.

According to Alden at Questyle, they are working on an updated version of their CAS192 DAC to include DSD. This should also make for an interesting partnership with the CMA800R. Up to now, I have tried the CMA800R with the Eximus, Naim DAC and the recent Teac DAC. Impressive listening with all three.

Yeah, I feel like sort of a guinea pig since the Questyle gear I have for review is all becoming outdated by now, due to upgrades. The CMA800 is obviously superseded by the CMA800R. The CAS192 is getting DSD support and possibly volume control - that part is not confirmed, but it would make sense if people need it to control their dual CMA800R setup. Lastly, the Q192 is supposed to get DSD support as well. 

 

Regardless, I'd say the original models give me 90+ percent of the final picture. And it's a beautiful picture indeed!

I'm sorry for bad english. I'm interesting in this amp.

What is the maximum output power (watt) from the amplifier on 50 Ohms (Hifiman HE-6) if to use two devices in dual mono?

It is in pure balanced mode if to use only one device?

 

Thanks.

In some ways I am not too happy to hear this as I would hope they would try to resist the current DSD hype and just develop the products they think sound best. The wm8741 they use does support DSD so perhaps they can implement it without changing too much.

 

I've never really enjoyed DSD and I can't really figure out where the interest is coming from considering (IMHO) modern hi-res PCM and DXD sound better.

The original CMA800 does 700mW into a 64 ohm load, and 1100mW into a 32 ohm load. So the HiFiMAN HE-6 should fall somewhere in between, close to a full watt per channel. I'm not sure what the CMA800R in balanced mode would be - probably double that, or more. 

 

Using a single CMA800 or CMA800R already sounds very good with HE-6. It's not balanced, of course, but it sounds exceptional nonetheless.

Check out the recent CES and T.H.E. Show coverage - for better or worse, if you don't offer DSD, people won't take you seriously.

 

That said, Questyle already developed the gear to stand on its own. Then DSD came along as a mandatory feature, and Questyle can add that easily enough. But the main focus was already in place.

Yeah it seems to be marketing hype at its worst. Even Schiit has a DSD product now and I suppose they have to do it just to be able to answer yes to the DSD question.

 

I still have my Sony SCD-XA777ES SACD player and about 50 SACD's stored away from 2003. At that time at least it was one of the two only hi-res alternatives to 44.1k, but it's hard to see the point of it now. Especially seeing as that everything is from a PCM or analog source anyways. From a 2014 perspective I just see DSD as being compressed DXD or other hi-res PCM. For me it's weird to see DSD making a comeback now as it had pretty much been a dead tech for so long.

 

Anyways I wanted to comment on this as I think it's clear that Questyle has a couple of really great products going and I hope they don't muddy the waters too much by trying to please everyone and include every superfluous feature.

I totally agree with your comments. I also used to have that Sony SACD, but sold it a very long time ago.

 

Initially, my plan was to buy the Questyle CAS192, and use a passive preamp to control my two CMA800R amps, but was told by Alden that they had stopped making it. Therefore, I was not prepared to pay £1200 for a discontinued product. Now, if I want a Questyle DAC, I will have to pay more to include DSD (a trend setting obsolete product).

I don't know if I'd write off DSD just yet. Things have changed enough that with a more convenient delivery model (downloads), more support (DSD capabilities becoming ubiquitous for most new DACs), and more actual native DSD recordings being made, it may just have a better shot. Back in the day, it suffered from a format war with DVD-A as well as a relatively limited amount of support from hardware manufacturers - the good players were very expensive (like your XA777ES) and the affordable players weren't resolving enough to showcase the difference. 

 

Am I a huge DSD fanboy? Not really. But I do welcome it as yet another way to get great sound from my system. And I don't think it hurts much for Questyle to add it in there.

Hey good folks :) 

 

Anyone tried LCD3 with Questyle to see if it has good synergy ? 

 

I have HD800 and don't know if i should get LCD3 or TH900 :tongue_smile: 

post #207 of 596

Somebody tried to compare this amplifier to Bakoon HA-21? it would be interesting to compare two devices to the identical principle.

post #208 of 596
long story made short just received mine yesterday......plug in power with Australia plug.....nothing complain...change to 220v...nothing. Over month wait. Must be fuse?

A local head-fier uses both LCD2r1 and LCD3 with the CMA800R. He seems very happy with the combo(s) :D

Thanks Anda 

 

Then it can't be all bad.. i guess dark headphones with a neutral amp could be a good combo.
