Can't get Acoustic Zen Adagios to sound smooth


I have owned a pair of Acoustic Zen Adagios speakers for over 4 years. They can sound very good, BUT also have a HARD AND UNSMOOTH sound when playing certain CD's. I have changed electronics from separates to an integrated amp, and recently purchased a Ayre CX-7e to replace a Rega Apollo. The Ayre easily highlights the limitations of the Rega player and outperforms it.

Nevertheless, the hard and unsmooth sound seems to prevail. It can also sound like an acoustic overtone, and (I think )the music looses its bloom or musicality. The current living space is well damped with maps,and rug hangings on the walls. I also have two 6 ft tall bookcases that contain only 70% less books than my previous apartment These shelves are in the corner, perpendicular to the speaker on each side of the room.

I encountered this problem before in a different and smaller living space.

I also recently changed speakers cables from a 4 year old pair of Audio Art SC-5 to a brand new pair of Grover Huffman which seemed to be slowly breaking in and are more detailed than the AA cable. I also replaced the standard wimpy power cord of the Ayre player with Panagea's new 14SE MKII power cord designed for just components, not amps. The Panagea PC is excellent, and has dropped the noise floor allowing for more detail to emerge. I drive the Adagios with the Rogue Sphinx hybrid integrated amp (100RMS)whose PC was replaced by an Acoustic Zen Tsumani Plus power cord.

I am beginning to wonder if there is another speaker that might provide a smoother top end performance and still have the taut bass, and detailed mids of the Adagios. Will appreciate all and any advice, even new speaker recommendations. Thank you

Jim, I agree with Lowrider and Soix that one of the first things that should be done is to try different 12AU7's in your Sphinx. FWIW, among currently produced tubes I've had excellent results, although in a completely different application, with the Genalex Gold Lion reissue.

Also, given that the Sphinx provides a headphone output (which I note BTW does not have the two tubes within its signal path), it may be helpful in diagnosing the perhaps multiple contributors to the issue to purchase an inexpensive pair of headphones. The Sony MDR-7506, which I own and which is widely used in pro audio and video applications, is surprisingly good in relation to its $85 price. Although as might be expected there is no comparison to my Stax's.

Good luck. Regards,

Jim, putting the manufacturer at fault, because you can't get them to sound good to you, is one of the funniest thing in this hobby I've heard.

Look, you've been struggling with those speakers for a long time. You obviously have a problem with choosing the right amplification, because they are everything but bright or harsh. 99% of the owners will confirm that.

I still probably have a few emails from you regarding Unison or Atoll amps for them, and you, if my memory serves me right, consistently come back to a class D stuff. You basically never enjoyed the Adagios. Why don't you want to Just get rid of them?

I wouldn't assume that its the amp that's at fault. It could just as easily be something else.

Zd, you're free to assume whatever you want. Of course It could be anything, including the ghost in the closet.

Given his history - two different apartments in two different states with the same result, makes me think it's the amp...or... simply it's not his sound. Jim's current CDP is one of the smoothest around. Since he likes class D that much, it would be better for him to sell the Adagios.

Personally, I never had that problem, and I have tinnitus. As of today, my Adagios are in my bedroom, and an Audia Flight Three integrated is driving them. Sounds amazing.

The biggest problem people make when recommending components is looking at the problem from a personal perspective. And its easy to do. I'm not faulting you for it. But people tend to recommend products and solutions that they like personally, assuming that it will be the correct choice for the OP. Sometimes it works, and sometimes it doesn't.

"Jim's current CDP is one of the smoothest around."

I'm very familiar with the Ayre 7. I'm one of the people that encouraged him to get it as an upgrade over his Rega. It is smooth, but its also very detailed, so it wouldn't be out of the question that the problem lies with his CD's themselves. Also, I don't see what class D has to do with it. Not all class D amps sound the same. Like you, I can only guess, and my best guess tells me the problem may lie with either the CD's themselves, or the preamp section of his Rogue. (No need to remind me that it's tubed. I know.) I admit that I could be wrong on this, but without hearing the system, that's my best guess. The only thing I'll add is that even though I didn't see the speakers as the problem, I have a lot of faith in John, so I'll always consider any advice he gives.
