Slot, tray, or top load?

+1 @nonoise 
the question was not about CD vs streaming.  No need to evangelise about the joys of streaming on an unrelated thread. 

Toploading for me, although a manual closing tray like Naim do, is a good compromise if you don’t want the CDP atop the rack. 

I brought up streaming as someone who was reluctant but who recently adopted streaming in the event the OP hadn’t thought much about it or what it might add to his/her listening enjoyment and how easy and painless it can be.  The OP can just disregard if they have no interest in streaming, but I don’t think bringing up other potential options an OP may not have considered is inappropriate in the least and can frequently be helpful and informative.  I know people have brought up solutions I hadn’t thought about in some of my posts and I greatly appreciated the information. 

That said, I’ve had three CD players/transports and all had front-loading drawer mechanisms.  Two of the three developed drawer problems so you can put me in the top-loading camp as well.  But even given my past experience, sound quality/characteristics would still be by far my overriding #1 priority. 

I have a vinyl rig too.  Do you want to tell me I should be streaming instead of spinning? lol

@jameswei
I don't know what soix would say, but having both vinyl & digital front ends myself, I definitely recommend you start streaming asap... Not as nice looking as a top-notch TT-arm-cartridge setup, but the hi-end digital front ends sure perform well, comparable to the analogue in fact!
And it's very simple to stream or download music nowadays!
(TT is a Simon Yorke pluto arm, old fm acoustics phono).

I think the real question is: What unit will be the most reliable and best SQ? While I think the top loader has the coolness factor and potentially fewer mechanical problems, tray style is probably the most common and there are many very good versions of it. I ended up buying a slot loader because of reviews and I like how clean the face looks. It's been rock solid dependable thus far.
