Preamp with Parasound A21+ amp?

Santa Barbra recommended the Benchmark LA 4

I have the Parasound A21 amplifier and the Backert Labs Rhumba 1.3 preamplifier. Together they make fantastic music. For your budget you can go to the Extreme version of this preamp.

BTW, posts like these always reminds me of a user - almarg - who is no more with us. He would have provided the details on why the Rotel might sound sterile and which impedance preamplifier you should be going with, etc., to make your system sound great with the amp you own. He is missed on this forum.

Hello @tjraubacher ,  I have literally been there.  I had Parasound amps and Classe amps and Preamps.  The Parasound stuff is built like a tank, sounds good, and lasts forever.  I have had A23+, A51 and A21.  But they can be on the warm side and never sounded 'great' until I got an Audionet Pre 1 G3 preamp. I got mine used for about  $3500 without the fancy extra power supply.  It was my first real experience with better equipment, and started me on a long and fulfilling upgrade path through Audionet amps and preamps.  I strongly recommend a call to Bill at GTT Audio.  He really helped me.
