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.

Why not Email DK. Im sure they can help you troubleshoot the unit. Good luck!!!!
Thank you all for your quick responses. I called dk design group today and they suggested that i try a tube change which i have (put the stock tubes back in)and that seems to have rectified the channel outage issue. However the music still is muddied and unfocussed on some passages.so maybe these tubes are also bad. Seems like long odds to me but maybe i need to order new tubes. so my question is now what kind? I have read many responses on this sight giving kudos to mullard tubes but would welcome suggestions on all options. I also have a linn adikt mm cartridge so i can use the phone section on the dk design integrated but it seems to pale in comparison to the line stage. I have an anthem pre-1 which i used (to take advantage of its superior phono stage)via its tape out into a line input on the dk design. This worked with much improved sound quality however i am now wondering if this in some way may have contributed to the problem. I was wondering what u dk owners who listen to vinyl do. I used to listen to vinyl about 75% of the time and miss the liveness very much. I will keep u posted on future conversations with dk designs. They have so far been very helpful and curteous. Thanks again for all of your help.
