VM540ML cartridge - what phono preamp is a good match

I recently upgraded to a Rega Planar 3 turntable, and put a Audio-Technica VM540ML cartridge on it, based on reviews and user comments here and on other sites.  The problem is that loud passages with massed strings and/or brass seem to get strident, overly bright and distorted.  That comes up frequently, since I listen to a lot of classical music.

Well, I found that this cartridge is spec'd for 47k Ohms resistance and 100-200 pF capacitance, which is nice to know, but Rega doesn't publish a capacitance spec on its tonearm wiring. My receiver (Sony STR-D515) shows 50k resistance but no info on the capacitance.  So, I suspect the cartridge and the phono stage might be a poor match, producing the strident brightness I'm hearing in the upper range instruments, but can't verify in the absence of specs.

So, my question is, if you are using this cartridge (or a similar A-T VM line cart), what preamp are you using to get good results?  

Thanks in advance!
There are EAR clones online for around $600... Single tube phono amps are generally hybrid op-amp based devices with a tube output stage.
Check out this guy's reviews of phono amps and lots of stuff in your budget.
Johnss & noromance ...are you talking about the ones from China that include EAR834 in the title? The ones I see are only $200 or so.  Are they pretty good?  
noromance ... I have played about 50 LP's on it.  Sounds a bit better, but the stridency is still there on some recordings...especially on 1960's DG 
roberjerman ... regarding the Bellari, does the input capacitance matter?  Can't find the specs on this unit, but several have commented that the VM540 doesn't like anything above 200pF total.  Does the tube overcome that?

Yes. Google 834 clone and read artofsound forum.

DG tend to be a little "hot".

If you can’t lower your Rega arm, try a 1mm shim between cartridge and headshell to change the VTA slightly. This can help tame the AT.
Yes, I've seen comments elsewhere to that effect about the A-T's brightness being tamed by letting them run a little low in the tail.  That's why I didn't add shims to raise the arm.  Or is it that it enhances the bass a little, which makes us perceive the treble to be moderated?

I wondered about the DG's from that period.  I have several late Mozart symphonies on DG - Karl Bohm and Berlin...the violins are a bit strident.  It just wasn't noticeable on the Technics linear tracker/AT152LP  I used for 30 years.
You may simply be getting more of The Truth from the transducer than you were.
