I don't think the Liquid spark will be enough to drive the K612. You'd also need a better DAC if you want them to sound really good. A headphone doesn't have to be lean if it's open, if you don't have body in the K612 that's usually a sign of it being underpowered.

It could be that yours is simply not properly driven. The Drop CTH can drive it pretty well, I have plenty of bass with SDAC and even more with a DF Red as DAC and everything is upfront. The K612 is known to be very hard to drive (it's not just about power). I once had the K601 (which is...

Anyone using it directly from Dragonfly Red or CTH+SDAC? I'd be curious if these tame the highs (since they do on the MSR7 for example). Thanks!

Changing the pads on your beloved K612 will also change its sound. The deeper/more angled the earpad (larger distance from driver) the more upper treble you are going to have (and if I'm not mistaken then K712 has deeper/angled pads). If you are looking for a more natural experience I recommend...

After owning the MSR7 and the R70x for a long time I find them quite the opposite. MSR7 is analytical with a slight warmness to it, a bit lean on the bass and a bit forward in the highs, with very good soundstage for a closed can. R70x on the other hand has elevated bass, the sound is much...

A bit late to the party I guess but I just got my K612 a week ago. I had a K601 a few years ago but I didn't like them that much because it sounded too distant, cold and analytical with the cheap dac/amp I had that time. Now I thought I'd give the K612 a go since I have a warmish amp (NAD D3020...

I had the same impression from different sources but as soon as I plug it in my Huawei tablet or my NAD D3020 it is a completely different headphone - much more balanced with more bass and less highs. Depends on source I guess and it's very picky.

Slightly, but fits well. Difference is a few mm only.

Cups are round so not sure if it helps.

Looks like this, but I ordered it almost a year ago probably from another seller (I'm sure it was cheaper than this). https://www.aliexpress.com/item/Leatherette-Replacement-Ear-Pads-Cushion-For-Audio-Technica-ATH-R70x-Headphone/32812213550.html

Hi! I just bought back my R70x 2 days ago to give it a chance with my NAD D3020 (previously I sold the R70x because it was a bit too polite and grainy in the highs). The D3020 does magic with my MSR7 so I thought it would be a good match with the R70x as well. Unfortunately that wasn't the case...

Yes, that's it. It can drive my Monitor Audio RX6 floorstanders easily along with my headphones. Yesterday I got my ATH-R70x back and they also sound great with the NAD. The DAC may be the weakest part of it but the overall sound is very pleasant and what I learnt from all my experiences is that...

Yes, standard edition is discontinued, MSR7b replaced it.

I had the same experience about a year ago when my NAD D3020 arrived. I wanted to simplify my desktop rig so sold almost everything including desktop amp, DAC, cables etc. I even sold my speakers and bought more efficient Monitor Audios, I kept my MSR7 and NAD HP50 only. The idea was that the...

Thanks! I really like them. I have had a few audio-technicas (both open and closed) and the A1000Z are easily the best of all.
