Reccomend a good preamp for me.

Personally I don’t subscribe to the "best preamp is no preamp" idea. A great preamp is the heart of a fine system. For many reasons.

"A great preamp is the heart of a fine system. For many reasons."
Please give the "many" technical reasons, not poetic reasons, for this compared to
"best preamp is no preamp idea."

Take a look at Parasound JC 2 (now including HT bypass).

Commonly call poweramp input is it not?
Turns an integrated amp into a 2ch poweramp?

Do your homework before making recommendations.
There’s some here (with all good intentions) that have no idea the preamp/s they are recommending can possibly drive 10mts!!! of interconnect that the OP has, to his JC1 monoblocks, without any limitations.

a good preamp for me. I have been getting back into vinyl again and even a cassette player so I am in need of a preamp that will have at least one balanced input and 2 more RCA inputs.

The way you have it direct, (better than any preamp) is the best you’ll get from the Rossini.
The Rossini has a 3ohm output impedance, and preset gain from 200mv to 6v output switchable. Using it with it’s own volume control with 10mt interconnects direct to your amps it will be the very best sound you can get.
Just make sure with the 200mv to 6v preset gain level switching you have it so the Rossini’s volume control is up near full for the loudest you listen at, so you know your not "bit stripping".

For a preamp to to give you more inputs and phono, I suggest using also an inline switch box between the Rossini and your amps so you can switch to a preamp from the Rossini dac this way you maintain the purest direct sound path for the Rossini to your amps still.

Like this, output of this switch box to your amp/s, Rossini on input 1 and new preamp on input 2.
