The Music Room

Bought a few items from them
Best to deal with them direct through their website or over the phone as they are willing to work on  the price somewhat if neither ebay or agon are involved. 
Never had an issue at all.

I recommend them. Traded in some McIntosh gear for an ARC GS150 power amplifier from them. Karl and Rob seem quite knowledgable in my opinion.

Yes very legit...I bought a used ARC Ref 5se. It was also supposed to come with brand new tubes... I emailed them back when it arrived and they sent me a set of brand new tubes for the 5se right away. Very good service and fast delivery. Packaging was very professional. They also did come down in price.It was in mint condition just as listed.  And they have a 30 day money back guarentee.  if not satisfied. Highly recommended. 

Excellent service, packaging and return policy.  Enthusiastically recommended!

I just completed my first transaction with them, an upgrade from my PS Audio P10 Power Plant, to the new P15 model.

Not only are they "legit", but they offered a MUCH BETTER price on the upgrade, paid the shipping for my P10 return, and did all of this in lightening speed.

I would definitely recommend them!
