ARC LS25 mkII noise level

What are the expectations on the ARC LS25 mkII noise level? Are these units supposed to be dead quiet in the system?

Mine adds considerable noise to the system. I swapped it out with another preamp (solid state) and the difference is quite significant.

Jazzgene, I'm pairing my LS-25mkII with a ARC SD-135 solid state amp. Speakers are Triangle naia's 93db sensitivity.

I have the LS-25mkII and have had it for about 5yrs. and have never had any issues with noise. I'm talking standing right next to speaker with ear to tweeter!
Sounds like it could be in the power supply(just guessing)
If you can do without for about 3 weeks, I would send back to ARC.
