I am looking for some advice about upgrading the tubes in my Yaqin MC-13S amplifier.  I'm running it with the following equipment:

 

Wharfedale Diamond 10.2 Speakers

BIC America F12 12-Inch Powered Subwoofer

Musical Fidelity M1DAC

JOLIDA - GLASS FX TUBE DAC III

Onkyo 7030 CD Player

Yaqin SD-32A Tube CD Player

 

I recognize that different tubes will create different changes in the sound of the system, and I'm not looking for a specific change; I'm new to tubes and simply want to play around a bit. 

 

Thanks in advance for all of your assistance; this is a great resource!
