Any info about input impedances (RCA and XLR)?
If you had two sources (new DAC with xlr out, old tuner with RCA out), and you only care for the Pre functions (never going to use the headphones), how does this compare with the Topping Pre90 or the SMSL SP400? I am thinking about an office system with a pair of active monitors (Neumann or may be Genelec). May be a passive Pre would be better? (I understand both Neumanns or the Genelecs only need very modest voltage, 0 or +4 dBu)
Thanks for your time.
