Tube pre-amp pop

Heck, if you bought both the amp and the preamp new from a local dealer, he should come to your house and figure out what the problem is for you. Especially if the dealer dropped the amp box while carrying it out. These dealers are supposed to provide some service for the premium prices you pay. Feel it safe to assume that your dealer made at least $1K on the sale of both units, he should make sure they work correctly in your home upon setup.

Don't be intimidated by the dealer. You did pay a premium, you should have new equipment that functions perfectly out of the box, or the dealer should be jumping through hoops to figure out why not. Too many bricks and mortar stores are going out of business. I fully recommend supporting them if they support you. It has to be a two way street though.

yeah, I used to be a very sucessful account executive for a phone company. Went thru a divorce then lost my high paid job. Moved out a small apt then sold all my beloved hi-end gears since I did not have any desire to listen to music for a while. Last year, I managed to save some dough and bought two 400Xi and now the Sp16l& 4 Bsst from the same dealer. He has been alright to me by giving my some good discount. Will see how he far he will and would take care of me. You are right about life is the two way street. Will be in touch John. Sorry. Don't mean to be too personal.

I would say that when you switch modes on the 16 always mute it or you will get a pop that is normal, I installed a new 16 in my dads system a couple weeks ago and it needs to be muted prior to mode switch and power off, I believe mute is auto on power on.

It's the dealer you should ask for exchange, not the ARC.

Does the pop sound quieter when the preamp is warmed up?

This is the deal. source on first, then SP16 on second ( it takes a minute or two and goes to mute by itself), then I power on the amp ( little buzz at amp then red relay lights then blue lights ). I then use the mute off ( boop noise) , volume up( pop noise ). Put back to mute ( some times "boop", sometimes quiet ). Unmute ( Boop). Not the regular "pop" or "tack" of switching device as in Krell 400xi. It not loud but not a regular pop either. Audphile1, I don't know if this hobby worth anything at all. I am stressed out and burned a pack of cigarette last night 'till 3:am . Chadnliz, Hello again ! I understand that too but I hate to unmute the SP16 since it Boops louder than out functions. At the dealer, his SP16 was dead quite from the speakers. NOw I am much more worry since I don't know if the SP16 or the amp. Thanks again.
