Faster alternative to the ASR Emitter?

I agree with you Charles1dad, as a current ASR owner I think it has everything Zuio wants along with speed & openness. BUT, Zuio: you might try to upgrade the input OPAMPS to the Burson discreet - I think that may just give you what you want - I'd never go back to the stock OPAMPS. The replacement is any easy unplug/plug in.

I'll second Mantis007's post above, ive yet to hear a more open sound than from my Burson equipped ASR.

Which model Burson did you use in the ASR? Was there any soldering involved?

Zuio, what vintage ASR do you own and what is the rest of your system, incuding the efficiency of your speakers? The older generation units possess a little more of a vintage tube sound. Cables (IC, SW, PCs) can make a significant difference as can a non-current limiting conditioner (despite what the manufacturer says). I use Dale Pitcher's latest "conditioner" and it took the ASR to another level altogether. The Burson mod is a great idea but after talking to Tony, it is not something for the technically challenged. Another tweak to consider is changing out the stock fuses. I put in silver HiFi tuning fuses and that made a noticeable difference.

The ASR has all the speed and openness you could ever ask for.

If you power/wire is not up to snuff it will slow/close your sound.

What year Emitter?

Cables?

Front end?

The Teo cables I have gives my Emitter a fuller/less open sound than the Stage 3 Magnus Prime. A simple wire change may be all you need.
