Gamma-2 (γ2) DAC Thread
Sep 2, 2009 at 12:24 AM Post #437 of 2,154
I'd be interested in a comparison between gamma2 and the twisted pear opus. Just out of interest. Still, I would expect the gamma2 to be better overall. Hence I will be building one soon I hope.

there's a cd that I've been listening to (a celtic sampler) that has some kind of 'bump' when the artist hit the mic or the table or something with a thud sound.

what was funny is that when I listen (even with headphones on) I still think there's someone banging on the wall or someone running in the hallway. its quite uncanny

this is a case of having TOO much detail (lol). when you hear the mistakes in the recording, its not always a good thing.

I should send mail to that performer, "you should re-record that song. and don't bump into the desk next time, ok? just sing, no banging needed please."

I have a CD by the great jazz pianist Randy Weston, recorded digitally during this decade, in which on good sound equipment and headphones with good low bass you can feel his feet tapping (hard) on the floorboards - - not as percussive sounds, but as sub-bass whoomps shaking the microphone stand and pushing on the diaphragms at extremely low frequencies. It actually makes it almost unlistenable, because it feels like your headphone is being moved around on your head; I have to switch from HD650s to Grados for it.

I never had that problem until I started using nice headphone amps and good DACS.

For sure I will need to get a new iron for that surface mount stuff. Hakko 936 is far too expensive for me. I need some recommendations / advice since my last cheap iron was almost useless.

I was looking at a Xytronic 253 (20W). It is more much more the kind of thing I am looking for...

What do you think?

I got the Hakko clone Aoyue 936 for under $50.00 shipped. I love it and have done a Bantam, Mini-3, and a Y-1 one with it so far as SMD goes.
I got it here on ebay. Very reliable seller from Ma.

BTW, I found that I just love SMD soldering! The resistors and caps are a bit fussy but those bigger chips like the DACS and even the little regulators are so cool to solder, and it looks so fine, clean, and neat when you finish it. It is also very fast!

How about one of these? I use the Station 1A.

Hi
ive gone through plenty of written material on the gamma1&2 i have a question for the gurus here
is the gamma series just a headphone DAC or can it be used with my home AV equipment too, i have a integrated stereo Amp and two mission m34i floorstanders, will this DAC bring a great change to music when substituted for say my computer/ipod as an audio source.

You don't have to use headphones, you can use it with any digital source that is compatible with the input protocols and plug in an amp to the output. It wouldn't be of use for an ipod since there isn't a digital output on the ipod (unless there is some digital mod that I'm not aware of), but other than that yes you can use it as your DAC.

As long as your AV system has a free pair of RCA line level inputs (it should) this dac will work fine with it. This is a quality DAC and is certainty much better than the line out of an ipod or computer so you will hear a difference.

It's the other way around -- the γ1/γ2 are primarily designed to be line-out DACs for use with an amp (headphone amp, integrated amp, or receiver, etc.). The fact that they are also capable of driving headphones directly is a bonus.
