Topping and SMSL have very good offerings with SOTA specs, second hand ADI-2 DAC is also a possibility. JDS Labs Atom+ is also superb for the price!

I can imagine especially with a unit from 2018, there's been tons of firmware updates in the meantime. Especially with the big update from last year, RME completely rewrote the code to be as efficient as possible in order to be able to house all these features on it's limited storage and utilize...

Hey, I just tried that track, no issues whether it’s on phone output or line output. I do have Digital DC protection on On for both outputs. Not the filter option or Off, this option should mute the sound in case DC content is detected but it did not in this case. Downloaded and installed the...

Listened to my speakers almost exclusively the last 2 months and decided to put on the 660S2 once again with Yosi Horikawa as the preferred artist for tonight's listen. I instantly realized I missed these quite a bit, the way the music simply envelops around you like soft waves on the shore. No...

Probably, I don’t think they have replacement glasses for it but you can always ask. A new screen is about 60 bucks + maybe half an hour of labour at a certified RME service point.

You’ll need to contact RME to replace the screen, ADI units had a few different IPS screens due to shortages and such. So you can’t just randomly buy one and hope it will fit and have the right connections for the PCB.

Smooth, plenty of speed and detail as well. Could use a bit more bite for the guitars on occasion but that’s just nitpicking and probably not preferred for a relaxed listen. To be honest I still need to hear a genre where the 660S2 doesn’t sound great. :)

After a few weeks spend with the HD660S2 and the NDH 30, I might sell the HD660S2 as well. It's a pretty tough choice and depending on your preferences you might prefer one over the other. To me the 660S2 has that nice warm, fuzzy mid-range with a little edge to sharpen things up for the higher...

Auto mode is a bit finnicky for me as well, I usually just change to DAC mode instead of Auto so I can select the source manually. That way the audio always works, I'm not quite sure how the ADI processes signals from different sources and what receives input priority or not. Might be worth...

Very nice Nomax, I was tempted by it a few months ago. But I don't think it's worth the 1k step-up in money compared to the ADI-2 Pro FS R I have now; I'll have to wait for the ADI-2 Pro 2 or whatever they are gonna call it lol. Unless I see a great deal on a Pro 2/4, then I might get an itchy...

I had it, it sounded very nice. Ribbon headphones or speakers for that matter, have a pretty unique sound signature. It had very tight and low reaching bass, never really bloomed and bled into the midrange, the mid-range is where it sounded a bit odd and scooped at certain frequencies but...

I agree, it’s a chameleon. Just like their speaker equivalent (KH 310), bad recordings sound awful and good recordings sound amazing. It’s one of the reasons I keep the 660S2 purely because it handles shoddy recordings a lot better. BTW I highly recommended playing a few intense FPS games...

The build design around the driver kinda reminds me of the HD 800, very interesting. Might have to try one, the “mid-range” priced headphone section is on fire lately!

I hate this lockable plug with a passion, I still don’t know how I got it locked in when I got the box but hey, if it works, it works… :) I think a regular 3.5mm plug a la Focal Clear would’ve been nicer, I never had an issue with those. Might be a good suggestion for the black edition if it...

Yes I have it right beside me lol. I just gave you technical impressions between the two headphones. :)
