O.K., downloads, streaming and more....but I still like many of my CD and SACD disks

Whatjd I have a few miles on myself and recently about five years ago I transitioned away from vinyl as my primary source though not so easy thing to do .
Having friends with digital front ends to help me along the way I went through EMM Labs ,  Esoteric and my last was a CEC transport and Rockna Dac then suddenly my world was up ended listening to a friends new music server and separate dac with an extensive music library all managed by a iPad .

I sat there choosing what ever i wanted to listen to including worldwide internet FM all with a touch my finger .

I brought over some of my favourite CDs to rip and listen to and was immediately struck at how much more enjoyable my music was on his system though sure enough I borrowed his server to listen in my own system , it took less then 20 minutes to decide to move on from using a transport. 
My current server is the Innuos Zenith mk3 with Phoenix re-clocker with both components is in my mind the most significant leap forward in musically performance I have ever experienced at once .

Whatjd I failed to add the Innuos Mini server with separate power supply storage space for 1000s of CDs all for under your budget and it has a built in dac .

DAC all the way. CDPs are dying while DACs are flourishing.

Yes but new CD transports are also coming back, EG: as Cambridge Audio’s CXC among others.
Just try to by a used old flagship transport these days, they cost twice as much as they did 1 year ago.
There are many (smart ones) that kept their CD collections when they ventured into streaming/servers, only to go back to their CD collection.
"Some" of the ones I know that didn’t store them away and sold them all off, are now regretting it and giving up on being an audiophiles, and feeling regretful for it.

GeorgeHiFi the same with vinyl collections back in the 1990s over the promotion of a digital revolution about to take place which will make vinyl obsolete and worthless.
There were of course some that bought into that notion and I bought a great vinyl collections nearly for a penny a pound .
Even though my collection of CDs are ripped and backed up I have no plans getting rid of them.
Ive owned some fairly decent transports and dacs though I’ve never enjoyed the sound quality near as much as I enjoy what I’m hearing now along with the fabulous convenience of managing anything thing I want to listen too with a touch of a finger.

Each to your own what ever works best for you .

If used is a consideration, the Yamaha CD-S2100 would fit the bill for the functionality and qualities you list. Check out the reviews online.
