I would like to share my break-in experience AND get some input as to what I have been experiencing so far. Within the first day a fuse blew! hmmm? Talked to Klaus and he gave me the fix. However, I was now disenchanted, not because of the sonics but because after less than a day the amp stopped dead in it's tracks (at least the left channel did anyway).
Alright....a couple days of just letting it play not paying too much attention to the rascal I decide to pull the speakers out into position and send some juice through the blue light special. Not bad
Upper mid needed some work and the bottom was a little loose but nothing terrible. The transparency was very much improved over my Sumo Polaris.
Now after about ten days things got weird
I mean really weird. The Stratos started to hum loudly enough to be heard for 20' and I was p***ed! It did this for roughly 24 hours and I didn't know what to think of it. Now for the weird part. After the hum mysteriously vanished I pulled up a chair for another critical session and holy cow! this baby took a leap into the clouds!
I was very pleased with what seemed to be completely different recordings. The female vocals, flutes, keyboard patches all seemed much more refined than two days ago as well as the bottom improving a bit.
Over the next week it swung all over the map. One day the bass was slammin' the next day there was uncontrolled sublevel flap! Then back to bassBliss. Whoa, I was wondering about the whole system symmetry thing now.
Well two days ago the hum came back! and of course I was ticked off (shouldn't I be?) Dang. I decided to pay careful attention this time to what I was hearing. The entire midrange section was loosing defenition, the sounstage was slightly off from a couple days ago, but the bottom was kickin' in nicely.
So the hum goes bye-bye again yesterday morning (whatever!!!)
I come home last night and spin some cd's not knowing what to expect. I've had this amp now aprox. 3 weeks and last night I became a believer! The Stratos is alive! What the heck just happened? I cannot describe accurately enough how open this thing now sounds. What will happen in another 3 weeks? that's what I want to know.
Now for some input about the hum. Can anyone tell me what's going on with that and why it may come and go as it does? will this happen all the time? does it need some attention by it's daddy?
I love what I'm hearing for the first time since I got the amp so I'm convinced it's a keeper but are all break-ins this freakin dramatic?
I'm all ears
Equipment= Forte model 2 pre, Adcom gcd700, Clements RT-7's. IC's I think are monsters and the cables are generic 10ga copper bare at both ends.
