Best preamps under $800

I need advice and suggestions. I've been living with a less than ideal set up for the past few months and it needs to be changed. I'm using the preamp section of a receiver to drive a Parasound amp. Speakers are Dahlquist DQ-30. The amp made an incredible difference! I never knew what I was missing. It's time to get rid of the receiver. I don't want to spend more than $800 on a preamp. The only requirement I have is a remote control. I don't need a phono section. I have that covered with a Musical Fidelity X-LPS. I've been looking at Musical Fidelity pre's A3CR and A3.2CR. They make great products that are afffordable. I considered the MAD Line 2A, but the lack of a remote is an issue. I want the convenience of switching sources and volume control. What other preamps should I be looking for? Are there any issues with matching a SS amp with a tube pre? Thanks in advance!
