I will say, the Dynavector is incredibly versatile, however, you need to fully understand a lot to use it properly.
I will suggest, you might also want to consider comparing Solid State Phono to Tube Phono, the difference will be clear. My McIntosh Preamp C28, highly respected SS: Surprisingly I preferred the 'toy' TT's switchable preamp. I LOVE my McIntosh Tube Preamp mx110z's phono.
