I have had the 5se and now the ref 6. Both are dead quiet with and without stock power cord. I believe all of your tests you will do will be of no help. Tubes , power supply , power cord etc. I believe something happened in transit. Especially that the tubes were left in the sockets. That should of definitely not have been shipping like that. I also feel that there is absolutely no reason for u to live with your 5 se making a humming noise. I definitely would not live with that no matter how minor it is. Or that it only reappear in between tracks. There is absolutely no reason for that. Send it in to Arc for repair and get it back to normal operating condition. I would also contact the seller and tell him that he didn’t ship it the right way and see if u can work out something that it has to go into service for his negligence. Good luck.
Problem with Ref 5SE
I recently purchased a 5se and took delivery the other day. Did not get a chance to open it up until last night. Upon installing it into system I switched it on and after it warmed up, I was very much interested in hearing how it sounded against my current 27. After listening to several tracks with the 27 I switched pre's and after a couple of minutes playing a CD I got some noise, almost a loud static sound coming from the right channel. It was not effected by changing volume controls or input selector. It went away after 10-15 seconds and then returned. At that point, as it was late, I shut everything down and figured I would take another look in the morning.
This morning I removed the top cover and pulled and reset the output tubes and then the power tubes. I fired it back up and still had the 'static' sound but now it also had a humm, like an impedance type hum and constant. I do not believe that the humm was present last night as it is quite noticeable.
The static type load noise seemed to have abated after the unit warmed up after maybe 15-30 minutes.
Can I assume that perhaps a tube was damaged during shipping? Do you ARC guys think a new set of tubes will fix this issue or am I looking at something more severe? Any additional suggestions to try and pin this down?
I rerouted the IC going to the amps to get them further away from source IC's and no help...
I am a little bummed, as my initial impression it that it is a leap from the LS27, my current...
