ok - after keeping the amp in car's boot for 3-4 days, I sneaked it in the house and kept it quite well hidden to prevent my wife from seeing it. In next 3.5 mins she came asking what is this new gadget.
I fired it up exactly (iirc) as gurubhais (multiple personalities) instructed me to. Nothing. No red light to be seen inside. I thought - I have screwed it by letting it bump in the trunk. Cursed myself for a brief moment, and then checked the connections again. Forgot to turn the wall-socket-switch on. Switched it on, and well, it started making music.
Since putting my kid to sleep in sane timing is very important, I went to sleep with amp connected to my BB's hp out, and philips hp9000 headphone playing away the music stored on bb. Just woke up, and listening on the same philips headphone. Pulling out any headphones from their hidings is too risky at this hour, and my kid can wake up and then ensure no one else sleeps.
It is sounding great. Right now listening to Radio Paradise on flycast on blackberry. Quite clean. But when playing music from bb (all lossless wav files) I heard some screeching noise once in a blue moon. I am not sure if it is recording, but I will listen critically when I will do a critical listening
Big thanks to Gurubhais for building this for me! It is sounding VERY nice, but I will reserve verdict till I hear it with hp50, hd650 etc.
