One thing that occurred recently that I thought was curious: One seller was selling his Beomaster 5000 tuner-only and his legendary Beolab 5000 amplifier in separate auctions. The tuner went for $550 or so, and the amplifier went for $250 or so. I thought that was backwards.
That is interesting.
It is also good news for me, because I only want the amp! I would have zero use for the tuner.
...but it completes the set....
