I have an update on the equipment rack that I am now using. Audio Advisor finally responded (following my 3rd email which was rather threatening). They would not replace the faulty parts due to the sale being older than 30 days old (even though the rack had only been is use for less than a week), but they did forward the telephone of the manufacturer. The rack that I have is a Studio Tech PA-04 which retails for $249 and they have a 6 shelf version, the PA-06 that retails for $379. I had 6 (out of 16) support posts fail, but the rest of them are fine (I tested then with a substantial amount of weight, 80 LB, and they all held up), so this was just an isolated incident. The good thing is that I spoke with John at Studio Tech on Monday and received 16 replacement parts this morning via UPS (this was less than 24 hours after our telecom). I randomly tested the replacements in a vice with a torque wrench and they tested fine as well. This is a bolt together unit with 4 upturned spikes that support each shelf (not just the top shelf). I had mine mig welded into a one piece frame, but this may have been overkill as the fit of the parts and the sturdiness of the rack when bolted together was excellent. The design of the rack (the upturned spikes) is very desirable to use with after market shelves and the stock shelves are good as well (just not up to the performance of the Neuance shelving for my source and tube amp). Anyway, I feel that the rack is a steal, due to its design features and price, plus knowing that the manufacturer is great to deal with is an added blessing. I only know of one retailer in the Santa Monica, CA area (Audio Video City), but the direct number for Studio Tech is 1/800/887/8834 if you would like to find other dealers and I would guess that they will do direct sales if there is not one in your area.
