Preamp suggestions 1200$ used


Hey everyone! thanks for taking the time to get this far and read my post!
I'm looking for a preamp for my system.
I'm an audio newbie, and my current system consists of the following:

Tyler Ref. Monitors
Rogue Magnum 88 amp
CAL CL15 cd player
SignalCable shotgun biwire (bananas)

currently using a Denon 1801 receiver as a preamp and I think that I could do much better than this receiver.
I'd like to ask for your help in building a short list of preamps 8-15 that I could follow up with some research and hopefully some inhouse auditions. Like I said, I'm new to this so any help is appreciated.

Things that are important to me:
1) resale value/demand (no joe's custom preamps)
2) I only use a cd player, soo...no other inputs are required
3) I need a remote volume control
4) I am using a powered sub along with my monitors so it would be nice if the preamp had a sub output (dunno if this is standard? or scarce?)
5) I dont have a preference to tube or solid, like I said, I'm a newbie, I just want SOMETHING for starters
6) I'm an upgrader, depending on the impact of the preamp I may choose to upgrade my speakers soon.

thanks for any help!

Thought I'd add that this preamp will function in a strictly 2 channel audio system.

I keep seeing "line level stage" in some of the explanations of the preamps, my understanding was line level was just another term for RCA any help here?
You can get a used Sonic Frontier Line 1 for about $1000.
It's one of the better hi-end tube preamp around.
built like a tank with hi quality components, 2sets of outputs,remote: volume, balance, phase, mute, inputs, stby has bypass sw for SSP, and more...

Just check out the WWW.. for Sonic Frontiers line series preamps and read the reviews...Happy hunting. Even though Sonic Frontiers no longer manufacture these product, they still provide customer support (repairs & upgrades).

Happy hunting and good luck. Hope this helps.
I thought that with the CL15 you did not need a preamp. Why don't you give that a try and use the volume control of the CL15
