Phono Pre Upgrade from Parasound JC-3?

If you are MC, Rega Aura. I’ve had it for 2 days and it blows my mind and can’t wait to get it broken in. $6k.  Has RCA and balanced.  Mute button, mono switch,  and gain of 63.5 db and 69.5 db.  You can switch capacitance and loading on the fly, just mute it first. 

Dear @snackeyp  : """  as I like the warmer sound of tubes... """

so then that's what you like not MUSIC because MUSIC is all you want it but warm.

Good luck with your warm BAT. Btw, the worst place to have tubes is at the phono audio system link.

Regards and enjoy the MUSIC NOT DISTORTIONS,
R.

Pass Labs XP-17 or if you can the Pass XP-27

Update:  I hooked up the BAT VK-P6SE yesterday and listened to three record sides before unplugging it and packing it up to be returned.  
I'm thoroughly convinced that it's not a good match for my system.  The JC3+ blows it away.  I have to believe this is more to do with the robust loading and gain adjust-ability of the JC3, and the lack thereof in the BAT, but beyond that, I just know it's not right for me.  

I think the Luxman EQ-500 is near your budget. Also, if you don’t need much adjustability, the Boulder 508 is astonishingly transparent. I have one and couldn’t be happier. Find your warmth in the amp or line stage not the phono pre.
