γ1 (gamma 1) DAC thread - Page 9

You see, if the γ1 would have an internal connection with the Mini³, and an other line out, I could use the γ1 with a bigger amp if I want to.
I can think for a few different reasons why that is a bad idea but at the end of the day they are both DIY projects so feel free to build them as you see fit.

but I would still have to unplug the Mini³ and plug in my speakers into the γ1 every time I want to switch from one to the other.

so you think there would be some prolems to create this setting or other things like size issues or heat ?
anyway, building is not an option for me unfortunetaly. all my tools are in my home country. along with a very good friend of mine who actually has the skill to do some proper soldering etc..
so I'll probably just end up buying a dac/amp off from one of the many shops of the internet...

btw I don't see why didn't anybody come up with an idea like this before. it's nothing really special or new about it.
it's all that a normal computer user, music listener person needs = an usb or preferebly sdpif DAC w/ HP amp and w/ a loop out for amped speakers.
and that's it.

spdif DAC because most of the new motherboards has spdif output on them, and why not optical if there is the option.

I've just finished my second y1... well, almost. I seem to have destroyed my 4.75 volt regulator. Upon examining the Wolfson DAC's data sheet, I found that it could tolerate up to 7 volts, so I removed the faulty regulator and and connected 5v directly to the where the regulator's output was supposed to be. It seems to be working fine now, and my computer's USB port is outputting a steady 5.01v. Is it fine to leave it like this until I order new parts?

You have already answered your own question so there is not much point in telling you something you already know.

Heh heh, thanks. That's pretty much all the reassurance I need.
Now that I'm in no hurry to replace that part, I just ordered it along with the illuminated switch, which digikey estimates will ship on 4/20.

So, interesting tip, I tested out using an external battery pack for the Gamma1. I picked up two of the Xpal Harry II Lithium-Polymer USB chargers from sellout.woot.com for $10 each. Heres the specs:

Power Capacity: 2000 mAh@5V
Rated Output: DC 5V, Max 500 mA

So far, its been powering my y1 on optical from the M-audio transit for about 20 hours and still showing a full charge on the indicator. I suspect I may get 50-60 hours on one charge (takes 2-3 hours to fully charge). EDIT: Did the math, 2000mAh should only last about 20 hours at a 100mA load. This is great for allowing me to use it with DVD, video games, or listening to music from room to room using the coaxial or toslink inputs. It also powers cellphones, mp3 players, and other portable devices. Battery power may be cleaner then a switching power supply, though this is twice the price for going portable. The cheapest now is $29.99 shipped on ebay, I have no affiliation with any sellers. I'm going to also see if it can play while charging next, its just taking so long for the darn thing to run out of juice.

Nice, I'll have to look into those battery packs.

I just received my y1 from mister x and am pretty happy with the way it sounds and with mister x's services
But one question...what happened to the bass? Will burn in fix this?
Right now I'm using it connected to my hornet, I have a CTH tube amp on the way, and AT M50's or triple fi 10's. Like I said I'm happy with sound, but compared to my headphone out from my laptop, the bass doesn't have the same impact.

Can't say I've noticed a lack of bass on my gamma. When you say bass, are you referring to just the quantity? Are you referring to low bass or mid bass? I'm not familiar with those cans, but is it possible your onboard sound on the laptop is emphasizing the low end?

It's more the quantity. It's there, and it sounds good, just the quantity isn't there. It maybe my onboard sound, but my m50's have about the same amount of bass running it out of my Fuze>LOD>Hornet.
But other than that, the y1 does sound a lot better than my onboard sound card

Just compared it again, and it's more the lower frequencies.

Listen to it for a few days without comparing it to anything else. On switching back to your other sources, they will probably sound boomy and awful.

It may just be that your ears need to burn in in - not the equipment

I found a similar thing with my fuze pumping more bass than the Gamma from my PC even though both are set to flat so it's not all in your imagination unless we're both imagining the same thing
