Do you think this unit would benefit from a treble and bass tone manual adjustment feature?

Did you know there's an entire site dedicated to reviewing gear by the feel of their knobs?...

hmm, knob feels really good to me. Maybe I am missing something.

I agree with cb3723. With all of those features, some EQ would also be nice.

@Armaegis Yes, Shigzeo introduced me to Knobfeel. Maybe it was my unit though, but the volume didn't feel good.

Wow, that was creepy, and inopportune timing that required some hasty explanation.  My computer speakers are turned up pretty high, and I clicked on a knob feel review, not expecting what I got.  The speakers were loud enough for my wife to hear the "sound effects", so of course she promptly came to my office to see exactly what I was up to on the internet.  Fair warning to others, the sound effects for knob feel reviews are NSFW if the sound is the only context someone will have for what you are up to... you might find your self having a discussion with HR that will start out pretty awkwardly (and end up that way on why you are spending work time watching knob reviews on YouTube ).

I tried out the HA-1 at the SF meet and I thought the volume knob was pretty nice, maybe it was a bad unit? Or maybe it's just preference, it did have a very heavy feel to it, so it was easy to make minor adjustments with a good amount of throw, which I liked. Overall I thought it sounded very nice, and I liked the UI and input options.

I played with my knob a bit tonight and it feels pretty darn good to me!  Maybe everyone's knobs are different(mine is very slightly slanted to the left for example, I don't want to bend it back and maybe hurt it, it definitely works fine), or maybe different folks have different sets of expectations on what playing with their knob should feel like. I don't know that I have ever played with a knob that would be considered to be awesome, so maybe my standards are just lower.  Too bad we can't play with each others knobs to compare how they feel.  I also didn't play with my knob until after being home from work for a bit and having a couple of drinks, so maybe playing with my knob feels better when I am more relaxed and not so picky and discerning, I dunno.
 
Thanks for another good review!

@Dan S We're talking about EQ - any idea why there's a load of comments with members talking of playing with their "knobs"? LoL - maybe some people should keep their private life out of the comments section of reviews?

Reviewing the knobs is apparently a more important part of the head-fi experience than I realized (I am new to this), I was just trying to catch up!  On a side note, no offense intended, but I am not much for an EQ to be added, unless it wouldn't require screwing with the current signal paths, add to the cost, and assuming it would be an opportunity cost issue preventing other features like perhaps addi media player type functionality so that it would be a truly stand alone unit minus cans (i.e. just add storage with content that it would be able to decode), kinda like the 105.  No need for a disk transport, just USB/SD/etc. input that could consume/convert digital content directly.  That is a tall order I know... just saying I think that would be neat .  Oh yeah, and upgrading the pre-amp path to be as awesome as the HP path.

When we went to dinner and drinks after one of the Tokyo shows I asked a woman if she'd like to feel my knob. I was talking about my camera, but it was pretty funny all the same.

And that woman's now your wife right?

Great read as always @Currawong! I was looking forward to your insight with regard to the HA-1.
I'm not a big fan of the Oppo PM1s (do they have a dash, can't remember) but the amp looked saucy

Awe Crafty Hack that's just classic! 
 
I was looking at buying the HA-1 but now that it's knob feel has come under fire... I may have to rethink my upgrade path.
