Stymax-Obravo HAMT-1 AMT Hybrid - Page 2

post #16 of 24

The real question people should ask is where is the crossover point ;) ... any crossover in the midrange 300-7khz suck.

 

15 to 300 dynamic and 300 to 25khz AMT, planar, rubban,stats would be interesting..

 

or 15 to 7khz planar and 7khz to ... AMT could be interesting

Listened to these cans at T.H.E. Show at Newport Beach last weekend.  They had two models (didn't know the model numbers) on demo with one retails for about $2100 and the other for "a few hundred bucks less," according to the representative.  I like the $2100 model a lot; they sound well balanced with good midrange and decent bass (sorta like LCD3s).  The demo was off from a mini iPad and rechargeable/portable amp, so couldn't judge whether these would scale-up or not.

 

Talked to the booth representative and he said that the crossover point can be configured by changing a cap inside (I suggest perhaps a mini-pot to set one's own).

 

The construction is industrial but looked better in real life than through the pictures.  The idea of dual-driver is interesting...But $2100 puts it in a very competitive range that hard to convince a buyer for a try.

The premium version of the HAMT-1. Note the difference in  the cup hinges compared to the normal below photos).

The fancy  model looks like a folded ribbon tweeter and the white and cheaper unit looks more like a planar type.

I'd really love to see some innerfidelity measurements of the Stymax-Obravo HAMT-1.

Hi, I just got to try these this past weekend.

First I loved how they look and they are pretty comfy. I found the mids and lows to be pretty good (tight and sharp) and the headphone is airy sounding. The seperation between instruments were extremely well.

But overall it sounded kind of weird to me. Like a thin and empty sounding. Like the voices and bass are there but it's missing something and weight.

They had a few magazines with reviews mainly from Europe. One had a fr chart so I took a photo.

If the frequency response is HRTF-compensated the level between 2-4 kHz is too much resulting in rather thin and high-pitched voices and propably in a slightly too hollow sound as well.

With headphones, that area between about 2-4 kHz usually should be a bit recessed to get a flat perception of that area.

 

By the way, I dodn't know the HAMT-1 had bassreflex-vents which can be closed. I guess the black thing that at first glance looked like some kind of sticker to me is in fact the plug for closing those vents (very first pictureon the 2nd page in this thread)?

 

Edit: I just discovered I had a magazinge called "Audio phile" (it is a special issue by AUDIO and Stereoplay) laying in my office desk for almost four months (my dealer sent it to me as a gift wehen I purchased an IEM in December) which includes the same article but in English with the same response graphs and pictures. So if I'm not mistaking there are three bass reflex ports which can be closed by the included silicone plugs. It says they are located on the rear so I assume those are the three oval "holes" on the picture with one being already closed, aren't they? That would mean you have to unscrew the back cover to regulate the bass ports.
