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.

If you decide to try new tubes I have found the Amperex PQ D-getters to work extremely well.Should help clear up that muddy sound you hear.I liked them so much i went for the pinch waiste's which are very three dimensional.The Seimen CCa is very good also being somewhat a tad more rounded for a more romantic sound in my opinion.Good Luck,Bob
I would recommend to anyone owning a DK VS1 MKII to find a set (matched if you can get them)of NOS 1960s era Amperex/HP(Holland made) 6DJ8s. Wow, what a winning combo. I had a set of Siemens/RCA 6922/ECC88s prior and althogh they sounded great, the 6DJ8s are unbelievable. The soundstage completely opened up and let me truly hear and enjoy what this integrated and my Gallo Reference 3.1 s are capable of. Cheers!!
