older CD transport vs newer ones.

I second sns with the Mark Levinson #37 drive and Philips CD-Pro transport - I used this drive built in Madrigal Proceed PMDT in combinstion with Reimyo DAP 999 EX Ltd. for many years and it sounded great, nothing came close.
When the laser finally died I tested a lot of different CD- and DVD- drives as transports only (Denon, Primare, Micromega, Electrocompaniet, PS Audio PWT, TEAC) - nothing showed the same sonic quality.
Finally ended up with Audio Research Ref. CD9 SE carrying again the Philips CD Pro-Transport, which is said to be one of the very best drives ever built.
The Project CD-Box RS-2T sounds interesting as it carries the Stream Unlimited (ex-Philips Engineers) CD-Pro 8 transport - this company also supplied the laser drive for the Wadia S7i which is not a bad reputation at all.
Furthermore I second charles1dad that the better the transport the better the sound! 
Probably you can find an AR Ref. CD8 used with Philips CD Pro Laser mech. and use it as a transport only with your Rossini DAC (I clearly preferred even the AR Ref.8 to the PS Audio PWT, the Ref.9 is even better than Ref.8 IMO)

FWIW,

I was using an AudioSpace CD8 (Phillips laser and 12 years old and $900) as a transport only going to a Theta ProBasic III DAC.

Moved to a PS Audio PWT (memory player that was/is also 12 years old and listed for $4000) and the PWT blew the CD8 away.

Off topic here, but I upgraded to a Mojo Audio Mystique DAC and it was another wow moment. I have ordered an EVO as I was so impressed.

My point is that you need to spend for a transport if you have a resolving enough system.

It never ends.

Thanks for listening,

@dsper,
Yes your experience with the P.S.Audio PWT mirrors my very good outcome. I had an early generation Esoteric with the VRDS mechanism/assembly. I used it for years and it was very good sounding (And reliable it still works fine today). Direct comparison to the PWT in my system the PWT was better sounding and more musically engaging.

@sns and others had different experiences with it. This is nothing new, diverse opinions and listening impressions are part and parcel in High End audio. Personal taste,system synergy etc. I do think that the Pro-Ject RS2 BOX is extremely intriguing with the latest "top loading CD" Stream Unlimited technology (And Blue Tiger servo board) and attention to detail and built quality. This thread has produced some very interesting and insightful commentary.

Was sold on streaming hi-res until I replaced my Cambridge CXC transport with the Jays’. Streaming still sounds great but something natural about the red books now. Both paired via I2s to Holo Audio May Dac. To think I almost got rid of the discs!

Lucky boy.
A couple of members in our Audio Club had thousand + cd’s they collected from the start of CD. And then sold them all when they went to streaming, chopped and changed streamers for a year or so, and then in the end gave up on hiend audio altogether, and now have budget systems, and we don’t see them at the meetings anymore.

I believe this is the reason why, streaming is usually always the later (red compressed) re-releases

Only album they ever did.
