Anyone use Big Sky Audio

Haven't heard of them, but remember you will pay shipping both ways as well. Do you know anyone local who can help you do the mods yourself? Shops can be great for repairs/upgrades although pricey, but DIY is fun as well!

I've heard they do quality work. There also recomended on Adcom's website for non-warranty repairs. Pyramid Audio in Austin Texas also recomended, they are closer to you.

Yes. I recently dropped off 2 Parasound HCA-1500A amps with Big Sky Audio. I moved from your neck of the woods (retired out of Sheppard AFB, TX) and had an opportunity to stop in Helena (home of Big Sky Audio) on my way up to Glacier National Park.

Prior to dropping the amps off I spoke w/Rick, the owner/repairman, and arranged to swing by his place. Rick's business is in his home and he has a very clean/professional basement shop. He invited my wife and I in and spent approx an hour showing us the shop/test equipment, discussing upgrades and showing me an HCA-2200 MKII in-work on his bench. He originally started in aircraft avionics, worked for defense contractors and then struck off on his own. My wife has an electronics background so the two of them talked geek and about the test sets on his bench.

We didn't discuss Adcom (he did say, though, Adcom was one of his specialties), but he's an authorized repair facility for Parasound. Rick has consulted w/John Curl, legendary designer for many of Parasound's best amps, so he is very knowledgeable on their products. Rick assured me I would be VERY pleased w/the upgrades and stated he had many repeat customers after having upgrades done (owner of the 2200 on his bench was a repeat customer).

My amps are still there (have been since mid June) and he's completed the full upgrade listed on his web-site. I'm currently visiting my parents in Washington State and am moving to Maryland later this month. I'll swing by and pick up the amps on my trip back East and can't wait to get my ears on them. Rick was prompt w/the repairs, even though he knew it would be a while before I returned to pick them up, agreed to hold the amps and contacted me throughout the upgrade process to discuss options. He wasn't pushy on anything and wanted to ensure I would be pleased w/the results.

I'm going to dedicate each amp to my 1.2tl's...bi-wire L/R channels of each amp to each speaker (not bridged). So, without hearing the amps I can't comment on the work, but walked away completely comfortable with leaving them and having the upgrades done. Give me a call and I'll share a bit more with you I believe you'll find very interesting...I'll PM you my tel # if you're interested.

Here's the post that originally pointed me to Big Sky Audio and it references Rick working w/John Curl on dcmartinpc's upgrade:
