You said [I consider tube equipment a nostalgic novelty and nothing more]. Might be time to open your mind and ears for your wrong about tubes. If you said tube amps cost to much or retubings a pain. Or tube amps of hi-power and great quality are expensive then your right. I you said I just don't like tubes fine but they are not a nostalgic novelty. They offer performance as good as SS. As far as SS integrated s the YBAs are very good, easy to listen to. The new MF A1 is detailed images very well but only 37 watts. Sure tubes are not for everyone. But they can produce wonderful fidelity.
