Tough call between the TRIO Model 600T supreme and the TRIO KT-917 FM only tuners.
Whilst the 600T had a MRRP of $650.00 back in 1976 compared to the KT-917's $1,000.00 in 1979,with inflation taken into consideration there's a lot less price difference between 'em than expected.
In-terms of sound quality,they're both amazing... So much,in fact that I can't really tell 'em apart,although the KT-917 might have a very slightly wider sound stage.In-terms of looks and build quality,I think they're both truly awesome,but if I had to choose just the one,the 600T would be pipped to the post by the KT-917.
