I have the Candela with ,almost the same amp. My stratos extreme amp has symphonic line caps on board & the 850 volt trany (3 months old) .


Using a Shiit Gungnir (DAC), my system was too hot with My 95db Tektons (got too loud too fast, no low level listening). It sounded great just hard to hold a conversation. I had to almost yell at the wife for her to hear me.
So I had to buy a DAC with volume control.
I bought the Oppo 205 so I utilize the voltage output adjustability . Now I can listen at any volume from very low to OMG loud.(I want to do the Modwright upgrade on the Oppo someday.)
I don't see a lot of the other guys using the Candela. But I do really like the way my system sounds with the Candela!
I bypassed the Candela (for fun) , going from the Oppo strait into the Stratos amp (no preamp). The system did sound good ,real good, but lost a lot of that magic that I was loving (tubes?).
I pluged the Candela back in, and wham the magic was back.
I have rolled a couple different tubes in, RCA clear top & Gold Lions. Telefunkin are next.
But to tell the absolute truth , I also drool over the Don Sachs model preamp.
Buying from Klaus is a bit confusing at first, He gives great discounts for grouping his components together & I really don't think I could've done a whole lot better (for the $) on the preamp/amp combo!!
