Hello, Boris.
History repeats itself. I was the first to reply to your speaker build thread and I do believe I'm first here.

You did an excellent job setting your son up with a great sounding system. Congratulations!
My son just last week moved into his first home (a townhouse). I gave him my old standby Nuprime IDA-8 amp, a pair of gently used GR Research X-LS Encore monitors (purchased from Nature Boy), a Rythmik L12 subwoofer, and Blue Jeans speaker cables. He and his fiance are pretty enthusiastic about their new sound system.
I'll post pictures tomorrow. The subwoofer is supposed to arrive this Saturday.
Michael
