Verastarr's Mike Powell upgrading SR "Stuff"

Hi David, I can probably explain better. First off we offer the cable upgrades. Then as far as the MPC, we took out the single filter cap and replaced it with dual FC type, and that was the first test and it clearly worked. Next step is replacing the diodes then replacing the cable run..

Finally I will be trying a much larger linear low noise power supply on it to see if or how much it makes a difference.  

@68 Pete, the story keeps changing. If I got Alex to work on this for you I performed a miracle on your behalf. If he could not do it, nobody could. If mods could not be done, what was there to fix ? Clearly it worked for a year, and if that was without mods, well its Denons fault my friend.. I'll contact you personally here since you dont seem to know how.. 

Reminds me of VAPOR AUDIO

The story has never changed Its been the same. It would not matter if Denon worked on it you could not deliver on what you said you would do....You and Hot Rod Audio failed not Denon or Alex.  Getting Alex to work on it was to cover your screw up. Not knowing what mods could be done to the 3930. Not my fault not Denon fault not Alex fault your fault. What makes it worst is your name calling and trying to drag down another cable co. which has nothing to do with our situation.  Can not wait to hear from you. My number and email have not changed
