… compare to a good preamp like Spectral DMC 12 or so.
Please let me know your listening expieriences
Thank you very much 
Not to be cryptic, but do you want a preamp at all? Some prefer their sound “colored” by a pre amp, others without (what I prefer). If you are thinking of a “straight wire with gain” that does not add its own character to the sound, then why bother? If the question is,“Does it have enough voltage and a low impedance output,” then the answer is definitely, yes.
