Anyone heard Cary 303/300 after 400 hours burn-in?


Has anyone had a positive experience with a correctly functioning Cary 303/300 CD player using high quality N.O.S. tubes, and after having used a high quality burn-in cd and music for a minimum and proper break-in period of 400 hours?

Has anyone had a positive experience with Cary's Technical and Service department in Apex, N.C.?

Has anyone had a positive experience with the 303/300 using the balanced outputs into a high end, non-budget balanced preamp (or directly) into a non-budget balanced amp and high end, non-budget speakers via high quality, non-budget intercnnects and cables?

Although some folks do not believe in modifications, has anyone had a positive experience with modifying a Cary 303/300 CD player?

There are always some folks that feel a certain piece of audio gear just does not suit their expectations, but, there are many variables with audio gear, when properly addressed, the very same gear may exceed the expectations of other Audiophiles.

I am looking for new friends to share your positive experiences with the Cary 303/300 CD player.

I love my Cary 300/300 but not with the stock tube,

I have roll several set of tube RCA MULLARD and

other brands and so far the sound is just no there. It is very important that you use high end cable with this unit. I have use it with Cardas Golden reference RCA and Nordost XLR. It took a long time for my unit to finally break in. I have notice that it sound better with a Cary Pre Amp, I used to have a CARY SLP-98 that I called my little sweet things I upgrade to the Cary SLP-05 that I call the beauty and the beast. I think that the Cary brand is 2nd to none.
CAD 120's Amp w/ Cardas caps, SLP98P pre. Never a problem with Cary customer service. Excellent sounding (tube) equipment out performing some gear costing lots more. You ought to hear what Lipinski L707 speakers sound like driven by Cary.
Worked fine & sounds great since I bought it new a couple years ago. I prefer the SS section to the tube in my setup running direct into the amp. I've even tried the recommended NOS Radiotechniques tubes. Upsampling off all the time. The 3V output of the 303 thru it's RCA's is just right in my rig.
I find that some recordings sound better SS, some with tube buffer; some with upsampling, some without.
