Cyrus CD8X ... glassy sound

Hi everyone

I have a cyrus CD8X running with NAIM NAC 102 and 2 x NAP 90/3, and PMC GB1 speakers. (I love my PMC speakers).

I'm struggling to love my Cyrus mainly because string sounds can be so glassy and tough. It can be amazing at times but its very inconsistent, showing up some CDs very badly. Having bi-amped my speakers things have improved a little.

But try playing John Elliot Gardiner's B minor mass recording from 1984 and the sound is unbearably hard and artifical. Most string quartet recordings for example that I play lack the true glow of a great string sound for me. There's too much artifical bloom around the sound and it sounds wrong to my ears (I am a violinist).

I was pondering a couple of ideas (3 infact)

- buy the Cyrus PSX-R power supply and see if that helps

- try out a Musical Fidelity tube buffer and see if that takes from edge of the sound (then I worry about the price of decent interconnects)

- Change the Cyrus for a Unison Research CD player (with the Class A valve output stage)

I don't really want to change my amps yet, though I suspect a Class A valve amp would give me the kind of sound I am looking for.

I don't listen to much else besides classical music.

Thanks

Neil

Ps : how can Art Dudley listen to Menuhin's out-of-tune, scratchy, sawing 1970s solo Bach on any system let alone a CD8X...

Re: Cyrus CD8X ... glassy sound

From the reviews I read about the CD8X, it sounds like the PSX-R is a worthwhile addition, but I'd be very surprised if it made your problem go away.

I feel the same about the MF tube buffer. I would expect no more than a small improvement in most systems.

I would first experiment with a few decent cables. You can probably borrow a few from your dealer to test them for a few days. You might be surprised at the difference a good cable can make over a bad one. Same thing about loudspeaker cable BTW.

If you could also borrow some other CD players to test in your system, that would of course be best. I have a Njoe Tjoeb CD player with a valve output stage and it sounds wonderful - magic midrange, no harshness, cost me only

Re: Cyrus CD8X ... glassy sound

If you have a high end shop that will let you try a few cables at home as demos, you might consider using a really fat speaker cable before giving up on the cyrus. Running a 9 gauge cable as full range as opposed to biwiring could be a good start to see if you can tame the tonal balance a bit.

I can say from experience that the Tara Labs Reference Generation II interconnect will roll-off the top and take a pretty healthy dose of the edge off and add weight down low.

I've heard the Cyrus stuff and as a house sound, I found them very lively and a bit thin. The optional power supplies would increase the spread and definition considerably, but thin liveliness remained. I would think that this gear would partner better with warm sounding speakers.

Re: Cyrus CD8X ... glassy sound

Thanks. I'm kind of stuck with Naim speaker cable, and my PMC speakers are very rich and lucious (compared to all the other brands I tried). I preferred the Cyrus over a NAIM CD3 (?) in listening tests.

I've got a micromega Pro DAC that sounds great with chamber music though not as detailed as the cyrus. The sounds still isn't quite right. SO I'll look over everyone's suggestions.

I tried out a few cables - maybe I can test out another one or two.

But I think the solution is a new CD player for me. I've got a friend who can lend me a unison so I'll give that a spin.

Thanks

Neil

Re: Cyrus CD8X ... glassy sound

Changing cables in an effort to mimic tone controls is in my view an unattainable goal. Fine tuning yes, but if you have a basic glassy sound then stronger remedies are needed. I had some success with the first version (X10-D) of the MF tube buffer, but whether this will work with your combination of a bright cdp and Naim amplification is another matter.

If you end up replacing the cdp you should consider something that up-samples - my Arcam CD93 gets closer to analogue sound than anything else I know at the price.

Hi All - I ended up buying an Opera Consonance Mk 1 Ref 2.2 that has a valve output stage.
