Penchum, I know you absolutely ADDDOOORREEE your mkV, but I think some of us would really like to explore our options with different opamp 'flavours' if not my question regarding the opamps wouldn't have been asked before already!

I've got 64ohm impedence on my JVC btw..

Just received my tracking number today

Some more days to wait ...

i think a good comparison instead of a GS1 would be the Gilmore Lite with maybe the external power supply.

I was interested in this amp earlier and still am sort of. I asked the question regarding the opamps because if I had the ability to fine tune the sound- well it would be a done deal by now.

Here is the response I got:

Hello Mike! The op-amp is indeed the signal path, however I would not recommend rolling op-amps as the MK V circuit design is not conducive to "drop-in" op-amp replacements, and doing so with most of the popular op-amps on the market would cause an undesirable DC offset. The MK V was really designed for minimal maintenance and tweaking as the components were designed carefully to work in harmony. The down-side of such "precision" is that is there very little room for tweaking and op-amp rolling. I hope this answers your question, please let me know if you have any others! Best Regards, David

Hope that answers any opamp rolling questions!

Thanks for posting the reply. I got one too, but was having trouble finding it. It's too bad you didn't get the MKV, but I understand the desire to swap.

LOL!

Tada !
It's there. Ordered last week and seven days after it's in front of me

My first impressions after 2 hours with the MKV: compared to the Zero headamp, the soundstage is much wider and I can hear precisely each instrument. Right now the sound is colder. I hope that it will improve after burning in.
Finaly the zero headamp is not ridiculous facing the MKV (I have a pair of OPA627BPs after the DAC and 2xLM4562 in the AMP)

You will notice changes somewhere between 45-65 hours, with the MKV settling in at 100 hours. Even though it is very good right out of the box, it just gets better as you go.

I still like the Zero's headamp with the right Opamps in it, but you'll see the difference much more clearly after some time.
Have a good one!!

Just got my MKV one hour ago. It goes very well with k701 and dt990. I was impressived by its sound quality. However, I think it does not fit to the dt880-- at least I can say not a good choice.

Add some pictures by the way.

Easy now, you need to burn-in that MKV. It will be a whole different story when you hit 100 hours. Then, do the critical listening with the different headphones.

Have you hit the 100hr mark yet? Looking to hear your impressions since some time has gone by. I think Freman told me in the Zero thread that his has matured into his fav.

anyone know how this amp compares to the graham slee solo??
cheers
