What preamp for my Shahinians?


I am driving my Shahinian Diapasons with a Rotel 380/channel solid state amp. I could spend up to about $6000 on a preamp. So far the ones I have heard in my system were not that impressive. (I currently have a Belles solid state).
The Plinius CD-LAD didn't sound as good as the Belles. The Hovland HP 100 had great mid-range but rolled off the bass too much and had tube ringing at high volumes.
It seems like finding the best preamp might take a long time. Can anyone suggest a pre-amp that might be good in my system? If your not familiar with Shahinian, I'd say they sound like Quad 988's but have more bass and play louder.
Thanks

Have to agree with Jond. 6k would get you some great gear.

Years ago I auditioned a Cary pre & the salesman had it hooked to some Cary amps. When he came back in the room after awhile & asked me how it sounded I told him it was fantastic but he was "cheating" by using the Cary amps-way better than the Adcom I had. He switched to a Rotel amp & the soundstage collapsed, the sweetness all but disappeared...what I'm getting at is the Shahinian's will sound way better on better electronics.

I had some Shahinian's about 20 years ago & thought they were great. Would love to hear some on my Pass/Ayre gear now.
Of course, it depends on what you are seeking, but based on what you said about the Hovland, have you considered the Placette Active line stage? I believe there's a used one still for sale on agon for $3500 or new at $5000. The detail, dynamics, transparency, and resolution are supposedly second to none.

And the fact that you have the Rotel amp, which is known to be a very nice amp, yet a bit on the warm/dark side of life, the Placette could be the perfect compliment.

-IMO
Perhaps worth mentioning here that Peter Thompson voices his Plinius designs with Diapasons. So a CD-LAD and maybe even a SA-250 would seem worth a listen.
I bought my Diapasons a year ago and started to drive them with a McIntosh MA6500 integrated amp, already to good results. Later, I had the new McIntosh C 2200 tube preamp, which was excellent in giving more and preciser soundstage, more natural sounding voices, better defined pop music, you name it. After that, I compared it to a C42 and C200 preamp. The C200 is even better than the C 2200, especially if you do not listen only to classical music, but dynamic pop music as well.
At a dealer's premises, I compared the preamp part of my own MA6500, the C2200, and the C200, running them with the amplifier part of the MA6500, and with a MC352 power amp. I found that the differences between the preamps were much greater than between the power amps. So I bought a C200, and the results are amazing. Given the fact that the C2200 costs 4500 $, and the C200 $ 6000 or more, the 2200 certainly is the better bargain. You should already be able to find one on Audiogon, I think. The Macs and the Diapasons work excellently with LAT International interconnects and speaker cables.
