OK, not sure  - since I'm new - that' I'm supposed to ask such questions. I will lurk more and learn more while doing so.    Thank you all very much.

Brand new to the site and though I would never consider referring to myself as an audiophile - I am a music lover and appear to be in way over my head.   I am currently pairing my A&K 100II with the FiiOE17 and so far so good. Since I am an old man - and I know my hearing isn't what I used to...
