Hi Fiddler
The mods include selected and matched cryoed 6jn6 output tubes. The input driver tubes should be procured through Andy of Vintage Audio who has the correct electrical characteristics per the manufacturer. ERS "stealth" covers which minimizes the effect of RFI interference and covers the impedance converters and is also added on several locations inside and on the bottom cover of the amp. Upgraded coupling caps which are also cryoed treated.
Saving the best for last or should I say pulling it all together and taking the amp to a greater level of performance than I could believe was possible is the hybrid silver wire for the inputs and power cables inside the amp. I had this mod done almost 3 weeks ago. I heard the improvement immediately but true to his word, Allan told me to wait about 2 weeks to realize the significance of this mod. I must say that I really heard it last night to the degree I expect he was referring to.
To owners of this amp that have had the other mods done, each has brought something different to the performance of the amp. The wire, which should be saved for last is easily the most significant. The sense of ease and greater inner resolution is readily apparent. Instruments and textures are better delineated and much more realistic, closer to the performance. I have never heard such transparency from an audio component. I had the opportunity to listen to this mod in my system through Fourproof's mono amps. I can certainly attest to Vetterone's comments concerning the bass performance of 2 of these amps on the Merlins. It was almost too much. But on material with low bass information, there was a sense of ease and power that one amp couldn't match. I was continually bombarded by puffs of air coming from the ports of the Merlins at 9' away, this at quite moderate listening levels.
