Have you contacted the manufacturer directly to see what they have to say? I would think they would know best. I've been working two out of warranty issues the past few weeks, one is audio based for a used component I bought used here on Audiogon, the other is something else, but both were resolved today through the individual company's customer support network. Both items are being fixed free of charge. So instead of relying on a bunch of guesses from people who probably know the DK amp about as well as you do or in some cases not that familiar with it at all, give the company a call if you haven't already, you may be surprised.
Dk design group ref. mk11 sound failure
Help! I recently upgraded system with, Audiogon used purchases, including already mentioned int. amp and a pair of Von Schweikert VR-4 gen 111 special edition speakers to go along with existing Sony es777 sacd player and rega p-25 turntable. I was in sonic heaven untill...... the left channell intermittently would go dead. I could rectify the problem temporarily by powering amp on and off via stand- by button. However the problem continued only more frequently. Then this morning while listening i noticed the music was very distorted ( fuzzy & unfocused )and finally both channels failed and i was faced with a horrible silence and a contraditory deafening doubt about new purchases.I am not here to disparage either of the individuals i purchased from , quite the contrary, they have been outstanding and very informative but alass the music is still non existant and i miss it. So my question, what could the problem be? I realize it is probably minor and hopefully easilly fixed but i cant troubleshoot the problem. Could it possibly be tubes? I Visually inspected and they seemed fine, seated properly and glowing. As u can scence by my ineptness in describing the problem i know nothing of tubes. The speaker cables and ICs(all audioquest) are fine and problem exists with both turntable and sacd player usage. I have noticed that the Int. amp seems awful hot , however, i have not had it long enuff to know how hot it normally runs. I feel so inadequate( same feeling i had when both exes said bye)but fortunately i have a great support group to help me thru this. Thanks again for any help or suggestions u give in saving this musical marriage.
