Daytona, I'm with you on your findings, although for me I prefer it disconnected, but at the same time acknowledge what I've lost regarding center fill and stage height. I actually prefer the disconnected tonal balance. Wouldn't you consider a volume pot. for adjustability over a resister. Looking forward to your possible solutions.
Linchpin, Great idea. I assume this applies only to musical content within the ipad or iphone? I'm stuck on the sound quality from the cd player above all else even with the highest resolution storage; lossless at a minimum on my ipod. Will an upgrade to my storage device w/recommended apps approach cd quality? If so, sign me up, sure can't deny the convenience.
Between what your both offering we may be able to wait out the next generation DSP implemented players surely to come.
