Dear @rooze : " but we invariably lose ’something’ and ..."
Trade-offs always exist in the audioworld and unfortunatelly for the tube lovers are accustomed to those high kind of distortions and these is what you lose changing to the SS alternative but is not a "sad/good " lose. In the same way that you will miss in the short time that " lose " in a short time you will start to " accustom " of the new kind of " distortions " ( if any ) with the 610LP.
Every one of us have their specific targets in our room/system, mine is to stay nearer to the recording and if with my SS phono stage I add and lost the less of what cartridge pick up from the LP grooves then I’m nearer to the recording because through tubes that add/lost is higher that what you could imagine.
My feeilng ( I can be wrong ) is that you are a MUSIC lover that know the live MUSIC kind of sounds. Now if you are waiting that the SS alternative gives you " more of the same " but " better " then don't take that " road " and stay as you are.
My take too is that @drbond ( I can be wrong ) think that you are just an audiophile and follower of the corrupted AHEE. I don't.
