First, make sure you match your amp to the new speakers.
I run my SLP-05 with a Mark Levinson 432, driving Sonus Faber Cremona. I added the SLP-05 to my existing 432/Cremona system, so did not try a lot of combinations. The new combo just worked. You might want to look at how the 432 fits with the 1028. I find that my combination gives plenty of the great tube sound of the SLP-05 while maintaining the ease of a SS amp. I am particularly pleased with the combination of the tube lushness with the detail and the punch of the system - much better than my previous Classe CP-65 pre.
