Preamp Question


I would like recommendations on preamps.  Here's my issue.

I have an Elekit 300B SET amp.  It only has one pair of line level RCA inputs.  I run two different sources--vinyl and digital.  The Elekit does not have a remote. 

I have a Schitt Freya preamp that is really something for the money. It has a remote.  But, my Manley Chinook phono preamp and Doge 7 tube DAC both sound better running direct to the Elekit amp.  The Doge has a volume/attenuator and remote so when I'm using that I'm in good shape.  

So basically I'd like to use a preamp to add remote and 2 line level inputs for convenience either without reducing the sound quality or even improving or changing it for the better.  Budget would be $2-4k new or used is fine.

I agree with mrdecibel here.  I would try the Freya in "passive" mode to see if you like the sound and to see if it is similar to running the DAC/phono direct to your amp.  That would give you an idea if a passive preamp would work for you, though I don't know that any other "true passive" would really be better than the Freya.  There are some passive preamps that have more than just a volume control and add things such as output transformers that can change the character of the sound - this gets into the exotic passive preamp area.
Another idea:  It's about a $600 investment test, but you could try putting in a quad set of PSVANE CV181-TII tubes in your Freya.  That would definitely increase the resolution and quality of the Freya, but like any other preamp, it will still not be the same as direct/passive.  Although, many preamps will add a "magic" to the sound that can be desired
Cables - the extra set of cables between preamp and amp could also color or slightly the sound as well.

Very transparent in my system, but I need more inputs and the tape loop. 
Good luck!

Look for a used Cary SLP05 which should cost about $4K. It's a great preamp. I wouldn't pay more than $4K, though.
Millercabon,  Your advice is smart and your post funny.  Nice work. 

Modifying the Elekit is not going to work because there's limited room inside the chassis to tie in another set of RCA inputs. And, even if I did, it wouldn't give me a remote.  I agree though that's a great mod to do if it were feasible.  I actually think one set of inputs is the Elekit's Achilles heel.  

I'm still researching all the great suggestions here.
