Half Rack Stewart Audio amps

by JD Letson from San Antonio, TX
August 13, 2009
Music Background: Hobbyist musician and speaker builder.
I am using the PA 50B to drive the compression horns in a multi-amped studio monitor/instrument speaker setup. I also have two of the PA 100B amps for the mid-bass (see my review on those). I am also ... read more [+]pleased with this amp although it actually runs a little warmer to the touch than the PA 100B's. Also, there is a slight turn-on click when turning this amp on and off. It is not a big deal, but when it is only driving a compression horn that makes it more noticeable. The factory told me the the turn-on click is normal in the PA 50B and not in the PA 100B because the two amps have different turn-on delay schemes. The amps sounds great, runs cool, and takes up very little space. close [-]

I was very pleased with the shipping speed and the way the stand was packed. I was especially surprised to see candy thrown in the box as well, thank you. It was very relevant to your name "sweet" water. Your "Thank You" inserts provided an insight into your service to your customers - and it really shows how you really appreciate your customers. Your customer service is excellent and I would not hesitate to buy from you again ... in fact, you will be the first company that will come to mind for my next purchase because I know what I will expect. Excellent Customer Service!
