Spectron Musician trun on noise / tweeter hiss

My understanding is that you are supposed to leave the Spectron amp on 24/7.

Regarding hiss, don't know what equipment you are using, i.e., preamp.

Finally, Spectron has always been very helpful, heck you can't get Simon off the phone once you get him. Call them and they will help you out.

I have the Musician III SE and I don't hear any hiss. And I am with Rafael...what's it sound like in just the first day?

Tmaple I have some questions for you;

#1 Once the amp is on how far away can you hear the hiss?

#2 Is it just a hiss or a hum? of any sort?

#3 What is your accociated gear?

#4 IC connections, balance or single ended?

I have the Spectron Muscian III SE. On turn on there is a momentary crackle. nearly inaudible but its there. The same is not true of turn off, just silent. I have absolutely no hiss, even with my ear right up to the tweeter its dead silent. Try disconnecting everything else in the chain and listen for the hiss again, 10 to 1 its NOT the amplifier, but something further up-stream

My Spectron Musician III SE Mark 2 gives a slight tick in the left speaker on turn on (I leave it on 24/7 but occasionally replace a power cord or speaker cable setup, so off the amp goes temporarily). No hiss whatsoever.

Thanks Folks for your responses. My upstream components consist of an AYRE K5X preamp amd AYRE C5XE universal player. All interconnects are balanced; Kimber Select between the pre amp and amp; Cardas Golden Reference between the disc player and preamp.

I've also encountered an issue with my tuner, which now only presents music that is total static!

However, my intial impressions are very favorable. I replaced an AYRE K5X with the Musician mainly because I was never really happy with the bootom end of the AYRE.

Once things settle down I'll be able to post my impressions.
