I think the stunning look of the amp adds a certain extend of placebo to the experience...
Placebo can be a worthy upgrade you know..
Probably for some the extra bass, although uncontrolled to some degree, is considered pleasing.
Regardless, concerning the Bottlehead Crack, there's obviously a lot of groupthink and confirmation and expectation bias going on here. Especially comments such as 'a day and night difference' when compared with already excellent amps such as the O2 should be ignored imo.
Have you ever heard the HD 600 with the Crack? They sound very different than they do with the O2. Better? That's subjective, but there is definitely a significant difference.
Groupthink and expectation bias have nothing to do with it.
I have a Crack and a very good SS amp. Depending on the music and my mood, I switch between them.
I do the same with my amps .
My tube amp offers at the same time a transformed and OTL mode and I didn' find night and day difference between the two although OTL mode provides a very high output impedance. I run only transformed mode with my HD800 and I really like the combo . OTL mode is way too loud to be comfortable.
So that's why Sennheiser concocted the HD600's unique color and finish. Dang, and all that time I thought it was the sound that enchanted me.
Good stuff :)
What warm sounding amp would you guys suggested within O2amp price? My Aune T1 + HD 600 can be to bright sometime and I read that the amp is the culprit. Thinking of changing to proper one. Crack definitely out of my league.
Why not the O2 then? I can imagine its response is likely flatter than the T1, so if it's bright still, then it's the headphone or the source.
BTW, really mooshed earpads can make the overall sound too warm but has sharp treble, so eliminate that possibility first.
You could try the m-stage, I used to have one and it worked really well with the HD800's. I haven't actually tried it with the HD600's but I'm guessing it will give you a warmer sound. Maybe someone could chip in if they have tried it with them?
Yep the M-Stage sounded good with the HD600. Slightly warm but still in the neutral ballpark. Bass and treble are a little loose with the stock op amp but with an LM4562 drop in the bass is punchier and more powerful, and the highs crisper.
Yeah that was the best opamp for me too.
I just got my pair of HD600s the other day and am loving them. I used to have a pair of HD580s and I had a couple mods on them and I'm liking them on the HD600 as well. Makes sense, they have the same drivers.
I got a LD Mk III used for around $200, sounds really good with the HD600/650's. I would think it would sound a bit better than the Aune. I hear no harshness at all..ever with this setup.
So, HD600 is consider bright or a neutral or slight bright headphone? Thinking of C5, Shonyun 306a, C421, Dot MK III. If somehow still bright for me, maybe sell this and get HD650. Hopefully I don't need to trade or sell tho/. I love this can so much.
