I used to think passive preamps were superior to active preamps given right the setup, but


my recent evaluation of a modded old SS preamp has me a little befuddled.  I've evaluated $10K+ active preamps in the past and was never impressed especially given their cost.  In general, I've found passives to do better job. I know there's ongoing debate on this.  But here's a very illuminating video on the subject by Bascom King, one of the legends of high end audio.

I replaced an ARC Ref 5SE with fully balanced copper slagleformers, then eventually upgraded to fully balanced silver slagleformers. I have tube sources (Ref 2SE phono and Ayon CD-07 player) plus OPPO 95. Gain is never a problem. For HT, I use additional 3 copper slagleformers (single-ended center and rear channels from OPPO 95) in slave mode in another box, hence no need for HT processor and HT bypass. For HT L+R main channels, OPPO XLR outs are used.

With autoformer passive, no background noise, high resolution, and controlled bass. And in multi-channel HT, I am getting high fidelity sound.  I may consider going active but will still use autoformers as volume control.
