Hi.
A little attenuation is not an issue as one seldom needs full volume for home audio.
You suggesting an active buffer is redirecting the question instead of resolving the question per the original post.
Any active topology bound to generate harmonic, & phase distortion to the incoming signal nomatter how good is the design let alone the complexity & cost involved. This is a realworld situation.
What buffer topology you would suggest with unity gain & min active distortions?
So often a passive device, be it an inductive or pure resistive interface
comes out better than many active interfaces. This is my long years sonic experience. FYI, I am still using pure resistive interface from ALL my programme soursce to my SS & tube amps, i.e. SS & tube phonostages (both do NOT have O/P impedance buffer), tape deck, DVD-audio & CD players. I am yet to audition any active itnerface that can deliver the speed, dynamic, transparency & musicality I am enjoying now.
Besides having superb fast, transparent & dynamic sound (which are a must to me), I have no problem with "significant high frequency rolloff due to cable capacitance" as you suggested. FYI, I am using 6 pairs 4N silver ICs I diyed, of short lengths. Longest pair not over 6ft.
I am a follower of UNconventional wisdoms.

- First off, it's off topic. Besides, active buffer is not all angel. - cheap-Jack 08:57:05 10/31/07 (0)
