Interested in opinions from users, on the effectiveness of the SRA platforms, if used for different amplifiers than the ones that they were originally produced for, as this is a component specific design. I have located a second hand pair of SRA isoBase XL+ and considering acquisition. I have an SRA Scuttle 3 Rack for a number of years and I am very pleased with the performance. Is the company still in business ? I have emailed them a week ago and still no reply.
