Faster alternative to the ASR Emitter?

Opamps is a great upgrade on the phono. I suppose the same benefits for the Emitter.

Interestingly, Friedrich at ASR has tried the Bursons and still preferred the 843s. To each his own.

Agear, I don't remember saying it was difficult? It really is easy, I just recommend using some DIP adapters to lift the Burson away from the cap right behind it. the swap takes less than 10 minutes - you should try it ;-)

Tony, I love to experiment and may take a crack at it at some point. I am having a sound room built in my basement, and thus there is so much flux in my system that other smaller "changes" may get swallowed. I surmised a certain degree of complexity not from our conversation but from other reviews of the mod:

I have upgraded to Burson op-amps in as ASR Emitter II amplifier and a high-end CD player.
This is a very worthwhile upgrade, better than monolithic op-amps in every aspect of the audio checklist. Give them a couple of hundred hours to break-in and have fun!
I have about 15 years experience in tweaking electronics. This is a winner, probably one of the best electronic tweaks.
Warning: pay attention and make a note of the location of pin 1 in order to avoid mishaps. You may need to solder a short ground wire between the op-amp and the component's circuit board. I had to add a ground wire on the ASR Emmiter, though I do not recall the reason anymore.
Enjoy!

Furthermore, I wonder what you are "hearing" given ASR's analysis of the Burson (slow and dull)? Another friend of mine tried the Burson opamp in a dac and came to similar conclusions. Some folks on the DIY forums were mocking the Burson experience as purely anecdotal. The Burson apparently generates more distortion, but maybe that's part of its magic...like a tube.

What I DO KNOW is that the ASR is sensitive to associated equipment, and its "sound" can change dramatically. Mine went from rather pedestrian, 2D sounding to 3D with the addition of a "conditioner." Go figure.

It does not seem credible that one would add a ground wire without recalling the reason for doing so. As Casouza is a self-professed 15 year compulsive tweaker, I might venture that there was in fact no verifiable reason to have done so.
