I have the Spendor S8e speakers and love them. I didn't like the full length apron covering all that good wood so I had a local cabinet maker made a much more attractive short cover for them for around $100. Pictures available upon request.
Mine are being driven very well by a Cayin A88T amp which is very musical and plenty powerful for the Spendors. In line with that is a Monarchy M24 DAC. Wonderful musical vibrant, alive, 'you are there' front-row-center acoustics.
My preferred tubes for the Cayin are SED KT88 power tubes, RCA VT-231s (6SN7)and Mullard CV569 (6SL7) which give it midrange texture to die for. My favorite tubes with the DAC are Amperex USN-CEP 7308 (white lettering). If you ever decide to try tubes, I don't think you can beat the above at any price.
