Dear Seraphim and Aristokles,
You're both very welcome.
Seraphim (and anyone else interested),
There's an abundance of online sources for Coptic chant, and 90% of the files offered for download are disappointing (either due to the poor quality of the recording or the cantor--this is primarily because most are aimed towards an educational, rather than an aesthetic, purpose), so, in the interest of saving you time, I discourage you from any attempt to sift through the plethora of available online downloads; i'm going to create an esnips account and will commit myself to do my very best to upload at least a couple of good quality files (from the number of CD's i've obtained over the years) every week.
