Had my Pioneer SA-8500 II refurbished with Carver Audio's "Chassis Refresh" service in February 2025. Besides a thorough cleaning inside and out, all capacitors are replaced. (Go to Carver Audio Repair's website for a better description of all that is included with this service.) Only a few rare days do I not listen to the Pioneer, which performs better than it ever has. It also looks as good as possible for a 50-year-old component. The same condition exists under the hood... it is absolutely beautiful.
If an audio component is worth investing in, this service will restore or upgrade to as close to new as is reasonably possible . Rolland (owner) will do custom modifications upon request (for an additional cost). (I requested the Pioneer have an IEC power connection installed.) Carver Audio will also do repairs only. (A Kenwood KA-9100 will be receiving the "Chassis Refresh" within the next few months.)
My experience has been that Carver Audio's the level of technical service, pride in their work and overall professionalism is hard to find in servicing home electronics. The reviews tell the story. read more
