Quick overview of my setup: MICS: AKG 451-EB mics with CK1 caps (this is the best sound for me. I've tried nearly all versions of Neumanns, KM84, KM184, U89, Schoeps, etc.. nearly all high end mics and the vintage pair of AKG's are basically silky brightness, exactly what I need) PREAMP: Hamptone JFET CONVERTER: Emu 1212m soundcard into DAW, Samplitude 8.0 MUSIC: Solo acoustic guitar, dreadnought bass heavy Samnta Cruz TRPro, and Martin D models, including D41 and vintage HD28. Also record some violin and mandolin. I use reverb only on occasions. I am very picky and I can hear extreme subtleties in tonal variances. I am also very picky about the tone I get from the instruments. So, I am wondering, based upon my setup now, it is obvious the EMU 1212m would be the weak link. But I ask, *how* weak is it? I am considering getting an older Apogee Rosetta AD 96k converter. These sell for around $600 on Ebay. QUESTION: Based upon my preferences and equipment, is it justified to upgrade to the Apogee Rosetta AD? Would tonal differences be obvious enough to justify the $600? Thanks for any help in this dire decision. Making me go crazy. ps. PLEASE I am not looking for anything higher end than the older Rosetta converter. If that wouldn't be good enough than I'll just keep the Emu card.
