Nice 2 channel system and gear choice. I used to have a TT and tube amp as well. I have a vintage Mac preamp I don't use and when I come across a suitable power amp I will try it for a 2 channel HT system.
You may want to try setting your speakers on concrete block to improve the sound and imaging. You can even paint them black and install stick-on rubber feet on top and bottom so as not to damage your floor and speakers. All are available from a home improvement store for very little money.
