Coaxial v. USB to RCA
EndersShadow
Posts: 17,590
I am using just a computer for my source in the office and this wont be changing anytime soon. Right now I am using coaxial from my motherboard to the HK 3490 which is driving a set of Monitor 60's. Eventually I am wanting to get into seperates and possibly a set of LSi 7's or 9's. I am wondering what if anything I gain by picking up a USB to RCA DAC? I am using MediaMonkey for lots of my music, that or the Zune software (yes I am one of "those") and/or Pandora.
For USB to RCA DAC's I am thinking something along the line of the MusilandMonitor 02, Yulong U100, or HRT MediaStreamer, but I want to make sure I am actually gaining something out of this before investing the money.
So let me know if you think its a worthwhile upgrade or just not worth the cash right now.

The Musiland Monitor 02 is excellent. They have extensive software and support, lots of flexibility and sound really nice for the price. I have heard the HRT is nice as well. One thing I personally don't like about the HRT is that it's powered by the USB port while the Musiland has a fully regulated discrete power supply. My experience with other components has proven a soild power supply is very important to good sound.
I have the Musiland and was a little skeptical at first, but I'm very impressed with the build quality as well as the performance.
Big thumbs up for it being simple, straight forward, not alot of fancy extra uneccesary frill's and great performance.
Definitely a worthwhile upgrade. Sound cards are really not ideal if you are looking for the possible fidelity.

+1 to the HRT, I use it.. If you're using a desktop with a decent power supply, then the HRT should be powered fine using the USB bus, however if you're using a laptop, I suggest using a self powered USB hub to power the HRT b/c I had a lot of static noise any time the mouse was moved or anything was done other than playing music when powered through a laptops usb ports, when I added a powered belkin USB hub the static was removed completely and sounds great!Main 2ch -

Yeah, I been reading up on your posts on it and did a bunch of research when I was thinking about going with active speakers. Its con's for that are no longer an issue given this type of use.
How is the computer interface program? To start with it will be the HK controlling the volume, but eventually I might eliminate that and go with a dedicated 2 channel amp, at which point all volume control would be through the Musiland software.+1 to the HRT, I use it..

Only thing I like about the Musiland better is that its got a headphone jack if I want to use it, and has a way to control the volume. The HRT has no volume control at all, and no headphone jack. Its one thing that irks me a bit about it and why I also threw in the Yulong as an option as it has both the headphone jack & volume control."....not everything that can be counted counts, and not everything that counts can be counted."

So if I am understanding this correctly when using coaxial from the computer am I using its internal hardware to convert from digital to analog. By using a external USB to RCA DAC I am using its assumingly better equipment to handle this conversion right? Is that the main difference?
Also are the DAC's in these better/worse/the same as the ones in the HK I have now? Haven't been able to find much info on the DAC's the 3490 has..."....not everything that can be counted counts, and not everything that counts can be counted."

Stand-alone DAC in most cases would just sound better than that of a receiver's built-in DAC.
As for the coaxial from computer, you're still just sending a digital signal to your receiver so the HK is doing the converting from digital-to-analog.

The Musiland is better than the computer soundcard and most likely the H/K dac's. You'll have to try it and find out. I like the USB interface better than coax or toslink from a computer soundcard."Appreciation of audio is a completely subjective human experience.

Yeah I think I might give it a try. I can grab the SignalCable Analog Two's from my Right and Left rear surround downstairs and use those. I dont think I will tell a massive difference between the SignalCables and Monoprice interconnects for my rears......I'm somewhat familiar with it but thanks for the links.

Yeah, I am thinking about getting a squeezebox touch and then the remote thing as well for downstairs to stream everything. But that's secondary right now. Especially since I just upgraded my Monitor 60's to LSi 15's and got the db840's in em downstairs lol.

If you get the Musiland and wanna A/B it with the HRT, let me know. I can definitely loan the thing to you. I am thinking that I will be away from my system for 3 weeks following my exams.

I might just do that. Although I might get the older Musiland 01 since the only diff is the 01 is USB powered like the HRT. And since its older I can get it for less.
We will see, gotta see how I can get this purchase to fly with the wife lol....."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -

External power make that much of a difference?

So been working OT this week so hopefully in a week or so I will have some additional play money to get a DAC. Thinking I might just get the Musiland 02, but I have a question that might be silly but it wont stop me from asking.
If I put a DAC converter between the computer and the HK, will the HK still use its internal DAC as well or not? How does it know not to mess with the signal?
Obviously the last thing I want to is to get a better DAC and then basically make it useless by changing the signal its sending out before it hits the speakers."....not everything that can be counted counts, and not everything that counts can be counted."

Sorry Enders I didn't get back to you on your PM. To answer your PM quesion I use it both ways and can flip between using it to convert USB to Coax for my AMC DAC8 or I can use it as a DAC..
To answer your question above no, you would use one or the other not both at the same time. If you had 2 sets of RCA's you could compare the two units to each other.
If you use the Musiland as the DAC then you'd use the analog outputs (to analog inputs on the HK) since it already would have done the digital conversion. If you use the Musiland as a USB to SPDIF/Coax?Toslink converter, then you'd use one of the digital outputs (coax or toslink) which would go to the digital input of the HK using the HK's internal DAC.
You can hook the Musiland up both ways simultaneously and use the software counsole to switch between both for comparison.
So to recap the Musiland Monitor 02 can be used as an excellent USB to SPDIF/Coax/Toslink converter or as a USB dac. It's also asynchronous.......which is what one wants.

No worries, people are busy with those things called lives . So which setup do you prefer the AMC's DAC's or those in the Musiland?If you use the Musiland as the DAC then you'd use the analog outputs (to analog inputs on the HK) since it already would have done the digital conversion. If you use the Musiland as a USB to SPDIF/Coax?Toslink converter, then you'd use one of the digital outputs (coax or toslink) which would go to the digital input of the HK using the HK's internal DAC.

OK, that was the part I was missing. I didnt know if I took the analog signal sent from the Musiland to an analog input in the HK that it would leave the signal alone.
I might try it both ways just to see if/when I get it.
I will have to grab the SignalCable Analog 2's from downstairs though as if I am gonna buy a good DAC, using .68 cent interconnects is kinda dumb
Its ok, I have 5 for my HT downstairs so I can grab the SR & SL ones and prob not notice any diff in that setup and should notice a difference in the office setup.
That and I keep eyeing the MIT Exp cables still on sale.....but dont wanna pony up more cable money right now lol...."....not everything that can be counted counts, and not everything that counts can be counted."

I still slightly prefer the presentation of the AMC, but to be fair I have had that dac for about 3 years and I'm much more familiar with the sound. I've only listened to the Musiland as a dac maybe 1/2 dozen times.
I plan to do some more experimenting. The synergy with the AMC and my tube amps w/the 5B's is just "there". I don't care for the AMC in the main rig because it's a little to bright and the bass is a bit bloated, but it just works in the office rig.
The Musiland is a very nice dac for the price. The build quality is very good and I like the flexibility as well as the regulated power supply.

Gotcha. My 2 channel setup right now is kinda in the humble beginning phases. I dont listen to it too much but want to start slowly building it up. Since I am all digital I figured the first step should be something as close to the source as possible and then work my way out (pre-amp, amp, speakers, ect).
Eventually the goal is to have a nice set of Maggies (thanks to NooshinJohn for the intro to them), probably the MMG's or the 1.7's with either 2 monoblock tube amps, or a 2 channel amp w/ a tube buffer and possibly a sub. But thats a bit off."....not everything that can be counted counts, and not everything that counts can be counted."

Simply for space reasons in the office rig I may just use the Musiland and closet the AMC. I just moved into a new house and still don't have the office rig up and running yet. Hopefully soon. I'll use the Musiland by itself for awhile and see if I like it as much as the AMC. New surroundings might just be the ticket.

Notice its not upsampling. Is that a deal breaker on these? I know the Musiland will upsample."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -
I don't really play the upsampling game. Sure it's nice if it does but not a deal breaker for me personally.
I've heard really mediocre upsampling units vs. a stellar std unit and the standard unit sounded better simply because it was designed better with premium parts.

I see no need for up-sampling. Either it's well recorded or it's not, and up-sampling is not going to make a poor recording sound good.

Somthing to consider, please keep in mind I don't know if this statement is completely accurate.
I read somewhere in either reviews or something...:
USB max data rate/sampleling is 24bit/96Khz
while digital(optical/coax) is 24bit/192Khz.
According to what I was reading there is no easy way for USB to handle 24bit/192Khz.
I don't know if you have material that needs 24bit/192Khz, or 24bit/96Khz is all you need.
I am sure someone more resourfull will clarify my statement.Current HT setup

Well I have some FLAC files, but honestly its gonna be mostly Pandora or from my Zune library (some of which was converted from FLAC to 320 bps MP3's, some is just whatever bitrate I got it in).
Not sure how much of a deal breaker that might be if true."....not everything that can be counted counts, and not everything that counts can be counted." William Bruce Cameron, Informal Sociology: A Casual Introduction to Sociological Thinking (1963) -
It is true, but since a majority of high-rez music is 24/96, I've never giving it a second thought. I do have a few 24/192 files on my computer, but they do not sound much different than the 24/96 stuff, and not worth the extra hassle and expense in my opinion.
-
If you have a desktop computer you may want to look at the E-MU 1212M PCIe. None of the limitations of USB.
From what I am have been reading the SQ is killer. It will work with both balanced and un-balanced connections, offers S/PDIF and AES/EBU also.
Just food for thought. -

MP3's, streaming internet music it won't make one bit of difference if it upsamples or not.
