Stereo Preamp to pair with Carver


I'm looking to upgrade from my current Emotiva PT-100 Preamp to something with more life. 

I am currently running 2 Carver TFM-35x Amps that have been fully refurbished and upgraded.
My current Speakers are DefTech BP2002TL and are bi-amp driven by the Carvers. 

I listen to mainly vinyl utilizing a ProJect RPM-1 with Ortofon 2M Blue cart. 
Occasionally listen to CD's utilizing Oppo 103. 
Some digital streaming utilizing a PS4. 

I have a Mofi Phono Preamp on standby as well. 

I'd like to stay under $1k and prefer used, as you usually get more for you money in that realm. 

Thanks in advance.

+1 Dehavilland Ultraverve 3 highly recommended. With the NOS Sylvania VT231/6SN7GT it hits the next level of being sweet and delicate. Offers the  transparency of a passive, and a huge soundstage. IMO you will not be disappointed with this pre.
I attempted a McIntosh C712 with not so good of luck. I believe the unit had issues and it's now on it's was back to the seller. 

All the units you have recommended are great choices. I'm a little stuck right now and trying to make a decision. 
Dustin, I have a Carver CT-27v that I use with my Carver TFM-35 and would like to sell. It pairs perfectly.
Hard to beat a new Schiit "Freya +" at 900 bucks new. Nothing seems to come close.
This thread is 2 years old guys. I’ll be in the market again, but I’ve moved on and have been happy with my Parasound Halo P5.
