others on this lively thread are welcome to chime in.....But please don't try to convert me to tubes. I tried a modified Dyna-kit st-70 years ago and ...don't get me going. A real pain in the tochos for mushy sound. Excuse this ramble. It's late in UtahMazikrav,
I have a set of the Double Impacts with the capacitor, coill & binding posts upgrade in Ferrari Red BTW.
I am using a Rogue Audio St-100 , that i just got a couple of weeks ago to drive them .
It uses four Kt-120s on the output and a pair of 12AX7s on the first stage , or input stage, and a pair of 12AU7s on the 2nd stage ,or driver stage .
I replaced the stock 12AX7s with some NOS Telefunken ribbed plates from the 60s and WOW......It is Absolutely Glorious sounding .
I have the Bass slam , speed ,and articulation of a solid state amp , but with the Tube magic everywhere..
If you did not know any better you would say that it is the sweetest solid state amp that you ever heard.
In fact it is the best amp that i have heard .
