Considering buying a CD transport

I agree with lowrider.

It looks like you are using Coax from your transport to your Bryston DAC.
Have you tried different cables? Different brands and length of digital cables can impact the sonics dramatically.

And I think you may get better results if you were using a CDP and not a universal player.

Thanks infection. I made a revision to my post.

How many CDs do you have, and have you considered a network-based approach instead? Yes, I am suggesting going a number of moves ahead, but you might end up there eventually anyway. 
Many of the best sounding digital setups revolve around:
- the music on a shared network drive aka NAS (Network Attached Storage)
- a router to distribute through your home via ethernet cable, wireless wifi, or through power line adapters plugged into a/c outlet
-  a network-based player which can be a specially purposed device, mac or pc, a dac
- wireless device to use as remote(i.e. tablet and/or phone).

The advantages are numerous and arguably provide additional flexibility in the future. Within your budget you could leap significantly in sound quality and gain elegance & simplicity in user interface. I'll shut up now. Cheers,

Thanks for the suggestions so far. I was hoping to avoid going the music-server route at least for now even though I know it's the wave of the future (if not the present) and may very well give me the quality I'm seeking. Since I'm a former managing partner in a local CD store, I'm still pretty attached to the physical objects, and I think my collection approaches 1200 discs. Also I'm at that point in my life when I'm getting resistant to having to learn whole new technologies. I'm aware of the PS Audio PWT and how good it is (from the reviews, at least) but even in the used market, it's over budget.
