A phenomenal new CD transport-Pro-Ject CD Box RS2 transport

I have had in-house for the last week Pro-Ject's new CD Box RS2 transport to review for the website Stereo Times. I was very curious to assess its performance because it uses the Pro 8 drive with the Blue Tiger CD-84 servo card. This drive was developed and built by StreamUnlimited a company started by the original Phillips designers that historically built the finest CD mechanisms. Only two other companies use the StreamUnlimited 8 drive and Blue Tiger CD-84 servo card, their pieces cost $16,000 and $39,000 compared to Pro-Ject's sane price of $3,000!

My reference for the last two years has been the excellent Jay's Audio MK-II transport that had out-performed much more expensive highly regarded transports in my system. Well, across every sonic parameter  (transparency/micro-details-overall dynamics/bottom-end extension/purity of tonality- a much more airy sound-stage with wonderful 3D imaging) compared to the Jay's Audio transport.

That's way I titled this thread a "phenomenal new CD transport" because while not inexpensive, it just might be a bargain based on its performance. Mind you, this superlative level of performance is based on using the switching power supply that Pro-Ject ships the transport with. I have shortly coming a custom 20 watt 3 amp linear power supply from Linear Tube Audio and Pro-Ject's own upgraded power supply to see if the RS2 transport performance will even go to a higher qualitative level of performance.

I'll be writing a full detailed review for Stereo Times in the near future. However, I wanted to share this information to GON members who still spin CDs. I have had numerous CD transports in for evaluation and this just might be the best sounding of all of them.

@amorstereo, Have you heard any of the CEC belt drives?

For e.g how would the CEC TL5 at the same price point compare to the the RS2 or the Jays CDT2, am very curious to know.

I have just got done listening for five hours to the Pro-Ject transport with Pro-Ject's upgraded external power supply and reference connecting cable between them.
It took this superbly performing transport to another level in the following ways:
1) Layering and placement of instruments in an airy and enveloping sound-stage became even more precise and 3D in nature.
2) The noise floor went down, so the smallest micro-details were revealed even more clearly.
3) The bottom-end is faster/tighter and better controlled.
4) There is even more a "sense of ease" that many would refer to as analog sounding in nature.

The combo of the Pro-Ject transport and the Audio Note UK 3.1/II Balanced DAC is by fair the best digital front end I have had in-house. My only slight criticism towards Pro-Ject would be they ship this great transport with a very inexpensive switching power supply, which stills sound terrific in spite of it, for 3K. Hell, add the cost of the upgraded linear power supply and sell them as a pair for a reasonable up charge.

Hey essrand,

Yes, historically I have had CEC transports, I use one right now in my smaller system (double belt model) along with many other transports including the Jay's Audio that you mention. The Pro-Ject performs at a higher level then any transport I have had in-house for evaluation or listening pleasure.

@amorstereo (Terry),
Thanks for the follow up. I am not surprised by the improved sound quality. I can’t recall any example of a component with  a standard switching power supply that was not improved with a good quality linear power supply in its place. What is the cost for the power supply upgrade? Agree that Pro-ject should default to the better linear power supply.

Terry , I’m currently listening to Dexter Gordon "Doin’ All Right" as a fellow jazzhead I suspect you’re familiar with this gem 😊.

Yep, power supplies.... the better the better the sound. I had a Sim 650 CD/DAC ~ $8K and hesitantly bought the ~$8K add on separate power supply... made a huge improvement. With the same kind of improvements you indicate.
