Need preamp recommendation

Hello, everyone-

I recently acquired an older (early 80's) Yamaha PC2002M power amp and am hoping to use it in my 2ch system which I am putting together piece by piece as budget allows. It is a solid state amp rated at 240w/ch at 8 ohms. I was thinking in the direction of a tube preamp but am open to whatever will complement this amp well. Budget is sub-$1000 if possible. Speakers are Goldenear Triton 2 towers. I've so far been looking online at the Rouge Metis, Anthem TLP-1, Emotiva USP-1, and a few others. I haven't auditioned any preamps yet but was curious if any of you had heard any with these older Yamaha amps before. I'm also open to the idea of ditching the separates route and going with a solid integrated amp if I could still stay around a grand. Just really looking for some solid suggestions. Thanks in advance-
