In addition to Jaybo's response , I would echo the tube suggestion , as many as you can do ie. amp , preamp and CDP .
A second addition would be a speaker change to something with a soft dome tweeter and a big bass driver . Also , two 7in. drivers are not as good as a single 10in. driver .
Of course the driver size will depend on the size of your room . And the box will be wider than the new designs of today that use the multiple smaller driver array for better looks . This is the reason that the older speakers , suggested above , look like kegerators !
These changes have made many of my CD's go from the 'For Sale' stack back into the 'Listening' stack !
Good luck .
