post #1 of 4
Thread Starter 

Hi all. I have an ASUS Xonar D2 as DAC connected to a Little Dot Mk III with stock tubes. I want you advise me to buy a better tubes for the amp. I have a Sennheiser HD 595 headphones too and I am thinking to buy a Sennheiser HD 650 but I don't know if the amp will can drive them. 50 ohm of HD 595 versus 300 ohm HD 650... Thanks for the responses.

I've had my LD MKIII for about 2 years or so now, and am loving every exquisite minute of listening to this gem!  A while back, I rolled a pair of CBS Hytron JHY-6AK5 tubes into my MKIII (found on Ebay), and I never looked back!  The sonic signature and synergy of my system is exactly what I was looking for!  I primarily use the MKIII as a preamplifier, driving a McIntosh MC162 looking into Magnepan MG12/QR's, and a Velodyne sub.  I use 2 into 1 connectors at the pre-out jacks, so I can accomodate an interconnect run to the amp, and another run to my subwoofer.  My source is strictly SACD/CD (Onkyo CDP).  This system has literally brought tears to my eyes!  I have several vids on YouTube under the name 'AudiophileTubes'.

 

I am only recently getting into headphones, and own the Senn HD-595's, which sound nice with the MKIII.  However, they are not high end enough for me, and I am thinking of going for the orthodynamic HE-400's by HiFiMan.  From what I understand, they have much faster transients, and better timbral accuracy since they have the sound signature of planar speakers like my 'Maggies'.

 

BTW, does anyone here use their MKIII as a preamp, and what gain settings are you using?  I cannot seem to figure out whether the MKIII sounds best at position 3 (default from factory), 4, 5, or 10!  The only variable I noticed here was how much play I have with my volume knob in getting the desired volume out of my speakers.  In position 3 I have to turn my volume control way up to get desired volume output.

 

Thanks for listening (pun intended).
