hello

glad to see i am in the top 10

will they be shipped out in the order that they were ordered?

i sure hope #25 doesn't recieve his bloat before me

also will the group buy go on past 25...? if so how much longer will you wait? i would prefer if the product begins to be assembled as soon as the counter hit 25

Also, I am in for 2, but have NOT made my order yet. Also awaiting cash . Next friday for sure..

amapro704

You will get yours in order of when you paid, so no worries my friend, you are in good shape! Production/ shipping begin when we hit 25, the minimum order for the pricing, but the GB will continue intil the 30th of this month. You will not have to wait if we hit 25 earlier.

DJiK

When you say at least, does that mean if you have more than 25 orders by the end of the month, you will accept them too?

What if the order amount is significantly over 25; let's say 50 orders by June 30... Will there be an additional discount to those paid?


Another question regarding the functionality: will this work without a sound card?
What if I disable the on-board soundcard in BIOS, would the DAC stop working then?

You can have multiple soundcards on any PC, it's just another device to pick from. But thats just it, you have to select the device that you want your control panel sound settings and/or music player software to send the audio out from.

You might want to mention that the USB receiver (PCM2707) is only capable of doing 16bit/48khz. So even though it has a 24bit DAC it's only receiving 16bits via the PCM2707 I2S interface. Also if your using XP and want volume control you are stuck with having to go through the Kmixer which downsamples to 14 bits then back to 16.

I understand that the first DAC is only 16 bits but doesn't that only matter if you are using the D to A function? If you are just passing a digital signal through it, doesn't it send whatever the OS sends and then the second DAC does what it is capable of doing?

Isn't this how external USB DACs that can play higher sampling rate music work? Unless they make high sampling rate capable DAC chips that can receive a USB format.

amapro704

Yes they will definately accept over 25, but I don't think there will be an additional discount. Unless maybe if we go wayyyyyy over- like 50 units- then I'll give Brent a call But really he is doing this to get his product into the hands of more people that can spread the word about the Bloat- more as advertising than to make a huge profit... And yes as T3 said, it will definately work without a soundcard!


Naamanf: Indeed, but they use that USB receiver for low jitter and its clocking capabilities- a much larger concern for this type of device than bit resolution IMHO because resolution is deceptive also. Many other 24bit DACs rarely function at true 24 bits. I honestly don't have absolute knowledge on this stuff, but I do know that the Bloat, even minus the upgrades, sounds incredible. Even with Kmixer and windows volume control. Thanks for the input though!

This is exactly the way I understand it to work.

dosquito

could someone please confirm this?

and how will it affect sound quality?

ps: is there any way to plug this into the digital out of a sound card?

amapro704

You cannot use digital out of a soundcard. I am going to get 100% confirmation on this, but I am @ 99.9% that no, it does not make the DAC operate at 16bits. And it definately does not affect sound quality negatively at all- this type of system is actually better. Let me explain:

This DAC is unique, it takes digital signal over the USB that is received by a BurrBrown chip (the one in question) and that sends spdif (still digital) to the main, dedicated BurrBrown DAC to do the conversion to analog. Since the first receiver chip sends out digital spdif signal its bitrate is irrelevant because there is no analog conversion, like T3 said. They do it this way I beleive for less jitter and better clocking to make the sound "cleaner/ crisper", something thats not easy to accomplish on a computer. Basically it has its own internal clock rather than relying on your computers clock. Less jitter and better sound! Anyone who has any questions about the souond quality should read the review posted earlier and if you have any further doubts, PM me and tell me what you're currently using and I will tell you the difference you can expect to hear. There won't be any dissapointments!

Thanks guys for the great questions!

Not at all. The USB receiver chip used is only capable of receiving a 16 bit signal. Period. It then converts that to a 16bit signal in the I2S format to be used by the DAC. So the DAC only gets 16 bits of data. Period.


Nothing really unique here. I personally own 5 other DACs that work in the same manner, 4 of which I built myself. The receiver chips bitrate does matter, and it isn't using SPIDF. Also the 2707 is used as the master clock but I wouldn't say it's the last word in jitter reduction.

I am not saying anything is wrong or bad with this DAC, just that you need to understand what you are really getting. There are many other DACs on the market that do the exact same thing that cost less and a lot more.

Thanks for the info man! Like I said, I'm not the tech guy, I'm the I listened to this and a thousand other audio solutions guy and this was hands down the best. I think you are taking credit away from the Bloat by not factoring in its size, simplicity and even its warranty when comparing it against things you have built. I completley disagree with your last line. You cannot show us a less expensive DAC with all the features and components of this for less...

dosquito

hey amapro...I think he was takling specifically about the 16bit conversion...not that there are plenty of other dac/amp combos like this for less

t3sn4f2

Now this has me worried. Volume control in Vista is excellent when coupled to a "24bit DAC". Would the Bloat be able to achieve this level of fidelity with regard to volume control?

I wish Brent would come by and help clear this up a bit
