Pre-amp upgrade time?


My current system: AR Ref110 tube amp, Cary slp03 pre, Cary cdp1 and ProAc Response D25.
I am getting Sony Hap-Z1ES this weekend. 
Music I like is mostly progressive rock and ambient electronic....
Love hearing wide soundstage, well defined instruments, clear vocals smack in the center but also quick, fast, tight bass.
Always tend to gravitate towards tubes but also felt in the past that they sometimes sound too slow and weak.... Wasn't happy with Cary 120 mk2, was OK with Sonic Frontier but didn't care for Pass Aleph 0s.(I know they are SS but sound like tubes).
Overall happy now but also ready for an upgrade..... I think that my amp is the strongest link in my system and while my CDP might be weakest...I think I would get most improvement if I look to upgrade my pre-amp.
What would you recommend and should I try to add SS preamp or stick to tubes?

Thanks

I agree with Spencer. I just visited Backert Labs last week to get my EAR 868 repaired. I got a chance to hear Bob's Rhumba preamp while there. Very impressive. The "fastest" and punchiest tube preamp I've heard most likely due to his patented innovative power supply plus, I'm sure, his careful build quality.
I should add, I have no financial connection to his company. I went to his facility on the recommendation of a few good folks on this forum about 2 months ago. To those people, I say thank you again.
Best, Fred
