I was staying out as I don't want to butt in on someone's thread, but I'll comment on this. The basic DSHA circuit (used in the DSHA1, DSHA2, Ravenswood, Apsara, Walnut, etc.) is differential. All differential circuits are balanced, not all balanced circuits are differential. I prefer differential circuits as I feel they generally offer advantages over single ended (and various non-differential push pull circuits), and very few drawbacks (and we can discuss that elsewhere). Steve feels differently I think. Yes, Steve and I go back. He was very helpful to me getting the cases made on my first batch of amps. We probably agree on more than we disagree (particularly about the use of transformers for gain), though we decidedly disagree on some fundamental stuff And I think he is mad at me, or thinks I am mad at him, or both. Not sure.
