a pal at work lent me his Geek Out 1000 to try over the weekend with my AKG-340 cans that I just bought for 200 euros last week direct from Austria, I sold my old pair of 340's a few months ago, and realised that was a big mistake, so I was very pleased to get a new pair in the original box which have never been used before - NOS )
his setup at work is
MacBook Air > Audirvana > Geek 1000 > AKG-601
my setup is a
MacBook Pro > Audirvana > Geek 1000 > AKG-340
after playing hundreds of .dsf files on both setups the Geek Out 1000 is simply amazing, the 601's sound perfect, but the old 340's have something that I cannot quite put my finger, they seem more real ( if ever that is a term one can use to describe listening to music with headphones) , classical music also sounds better with the 340's as well, but I have a soft spot for the much underrated K-601's, so I bought a pair in fantastic condition which should arrive in a few days time.
for such a simple rig, I could not be happier and have finally decided after many months of testing lots of DACs to buy the Geek 1000 on ebay, and sell my Musical Fidelity X-CAN v2 amp to part fund it
just to say a big thank you to Tim for keeping me on track, my love for DSD is growing daily
