I have both the K550 and latest K553 - both with replacement cable mods done by professional (on this site). My K550s are very well used and highly burned in after years of moderate to high usage. My K553s sound similar but definitely have lower and more detailed bass extension. I find...

Very interested in the K550 MKIII vs the sound signature of the original K550 MKII which I own. The K550 IMO are very neutral and sound very nice. I will say however, that the long single wired cable in the K550 MKII is not a good thing. Overall I'm not thrilled at the cable quality of the...

I like your comment on the V-DAC II, and agree with you that it's still relevant for me even today. I have used my V-DAC II in my audio system since October 2011. I have changed and upgraded several components but I've kept my V-DAC II. I use my V-DAC II with a dedicated HP laptop Quad-core...

Thank you very much for that tip.... I tried various combinations with the demo software and other info here in this thread. It was a bit frustrating with only a few minutes of output and then what the demo version of OOYH does (goes silent without paid versions of anything). What works for...

I highly recommend using the Pyramid High Power Noise Suppressor NS-12 (Amazon has it) to connect in between your battery and the MK-II DAC.  I use the NS-12 at home connected to my heavy duty Pyramid PS3KX 12V PSU.  With the NS-12 noise suppressor connected, my noise background is completely...

I have no problems with direct USB connection from Windows 7 Pro to my MK-II DAC.  The Pyramid PSU is easy to connect to the MK-II DAC. I use USB highest quality Pangea cable to connect.  I disable my local Sound card on my Toshiba laptop and after I power on my Pyramid PSU, I then...

Thanks for sharing your story.  If I had unlimited disposable income, I would have a different system. That's doesn't mean that I don't absolutely love the sound of my system now.  I may never be totally satisfied without trying to improve it some manner, and I suspect most audio enthusiasts...

Thanks.  I will say that to me anyway, there would be better ways to improve the overall  sound of my system, if I had extra funds.  I love my system for now, just the way it is for what I can afford.   If I was going to make improvements, for me, I would spend money on even better...

I have to take very strong exception to your comment that the V-DAC is terrible for anything at all.   I own a Musical Fidelity V-DAC MK Version II (24 / 192 Asynchronous USB IO).  I use a Pyramid PS3KX 12V PSU with a Pyramid High Power Noise Suppressor (NS-12) for my PSU needs.  It is...
