Most compatible phono pre for Lyra Delos

I am happy with my current set up but I believe I may be able to retreive more detail with a more compatible phono pre. Your input will be greatly appreciated.

I would describe the current sound of my system as fatigue free, easy to hear, articulate, spacious, open, and balanced. In good recordings I get good body with particular emphasis on upper bass. It does not sound bright, nor thin but (depending on the recording) sometimes lack some extension at the frequency extremes.

I mostly listen to the likes of Dire Straits, Supertramp, Steely Dan, Alan Parsons, Eagles, Ryan Adams, Wilco, Jack Johnson, James Taylor, Norah Jones, Diana Krall, Natalie Merchant, Tom Petty, etc. You get the picture.

I also enjoy listening to Bob James, Stan Getz, Herb Albert, Chuck Mangione, Sergio Mendes, etc.

My current system:
Rogue Audio Cronus Magnum
Output tubes – Tung Sol KT120
Phase splitters – Genalex Gold Lion 12AX7
Amp section drivers – Genalex Gold Lion 12AU7

Highly modified Rega RP3 (comparable to a RP8)
Lyra Delos
Dynavector DV-P75 (in enhancer mode)

GoldenEar Triton 7 tower speakers
StraightWire Maestro speaker/interconnect cables
APC H15 1.5kVA Power Conditioner Unit

The Rogue Audio Cronus Magnum needs no introduction.
Same with the Lyra Delos.

The Triton 7 s are able to reproduce a detailed sound with adequate frequency response and sharp transient response. Snap is there, but they are not as dynamic as you would expect compared to a much larger speaker.

The most remarcable aspect of the triton 7s is its ability to produce a wide, open sound with width, depth, and height. They are capable of producing a sense that a voice or instrument is in a particular place in the room, almost dispearing like a good quality monitor would do.

So the question remains; would I be able to obtain more levels of resolution and maybe dynamic impact with a more suitable phono pre for my Delos?

I don't mind buying used/demoed (All my gear is either used or demoed with the exception of the Delos and RB8) but I definitely would like to stay under the $1,500.00 range.
