Firewire to SPDIF


Does anyone have any view on the superiority to Firewire to USB in terms of conversion to SPDIF.

one negative of USB is that if you are using a SPDIF conversion device then using another device like external HDDs is not recommended. it is also limited to 48/24 ..both unlike Firewire.

the only good device seems to be the Weiss Minerva..but that in the Uber price range for something like this.

Does anyne have any experience with Echo Audio ?

My solo sounded good out of the box. I don't recall a difference after break in. I run my firewire streight into the gateway motherboard (Intel w/southbridge chipset). I don't use a firewire card. Are you using the power supply for the solo or taking power through the firewire interface? I am not using the power supply and feel w/o power supply, it sounds better (on my rig). I use the same digital cable inthe the DIP. I'm not familiar with the Compaq card. Is that a PCMI to firewire card? I may try a different firewire cable as well. I may also try a new firewire cable instead of the old one (not sure why, I just would).
USB 1.1 still no where as fast as Firewire. USB still utilizes the CPU in your configuration and transmits packets, not data streams. Try firewire.
The USB 2.0 can pass 24/96, but not USB 1.0. (USB 2.0 maxes out at 24/96). USB also uses the CPU which drains power usage (though there are some new USB utilazations by third party manufactuures which bypass the CPU issue). I have long been a proponent of the superiority of firewire over USB as respects PC Audio and from recent posts in other forums, more users are coming around. USB was never intended to pass audi. It was intended to daisey chain peripherals, ie mouse, keyboard, gamecontroler, printers, etc. I do agree that the new implementations of asychronious USB utilizations have narrowed, possibly eliminated the advantage, if processed (and installed) correctly. These are new developments and I have not had an opportunity to compare them. I am thinking that even with the new outboard USB advances, the datastream may still be better when handled by firewire as these new USB implementations are not able to change the issue of USB transmitting packets of info, rather than streams, as firewire does.
...you can (and I do) convert firewire to spdif for my dac (M Audio Firewire solo). Do a search on firewire vs usb for audio. Here is just one of the many links I have found:

I haven't used the Echo.
I like the M Audio alot. I tried the Trends with the stock and the battery power supply and neither worked for me. I just dismissed the usb altogether. The Maudio into my monarchy dip into Music fidelity XDac 3/PSU gets me close to my Esoteric xo3 se.
Not sure on the cables. I'm using the stock firewire that came with the MAudio and no issues. I have seen upgraded usb cables on line but have't seen any firewire by the high end mfg (Cardas, etc). I would bite if I saw one.

Good luck with your upgrade. I'm sure you will love it. Please report back.
Arj,

Pls also check your buffer size in the MAudio control panel. I use 512. Sync source is internal and spdif output source is set to mixer. I don't have the "disable direct monitoring" box checked. I am using WASAPI and JRiver 13.
Rabbani, I'm not up on the Hi ez downloads as I have only ripped CD's to an external HD using EAC. The Maudio (Firewire Solo) does convert Firewire to SPDIF, which is how I use it. I have a very simple need (no recording, multiple tracks, etc) so I ent with the Solo as I didn't need all the inputs that the 400 & 800 offer (saved some money).

I prefer Firewire over USB and the Solo allows me to (1)use my PC output of choice and (2) doesn't limit me to Dacs with a USB (or firewire--if there were any/many)input.

The firewire goes into a Monarchy DIP, and then MF XDAC V3 (w/PSU) into tube intergraded. The Solo does handle 24 bit 96kHz. They have a great website-www.m-audio.com
I just played back some HD Tracks I downoaded a while ago and the MAudio Interface does show 96kHz. Listening to Rimsky Korsakov now and it does sound......AWESOME.

I should look more into this Hi Rez stuff.
Al, I missed your post. A sound card with spdif out would be great. I didn't want to spend the bucks for a top flight sound card (Lynx, etc) so just went the firewire route. I used spdif out which was on my motherboard (SigmaTel) and didn't like it. I'm sure I would love the Lynx spdif out, just, at this point, I'm kind of done opening up my 'puter, configuring sound cards, driver compatability and all those lovely windows issues (I'm not a Mac guy). Just my preference.
Rabanni,

I always built my own computers (never was a Mac guy) but got tired of it and purchased a gateway 2 years ago. Went a bit overboard spending $5,000 (it is a screamer) but I do photography so wanted the fastest available (CPU, HD and RAM) so went for the fastest I could find. You don't need to get that crazy. I absolutely HATE HP and most other commercial brands - they think loading up your hard drive with (nonsense) software is good while it only kills your operating system (in speed, boot up, etc)performance. I went with Vista OS. Would probably go windows 7 today. I have had a few Dells and as long as they followed my specs when they were built, I have not had any issues. (I would have gotten a Dell instead of the Gateway but they insisted in selling me a Blu Ray drive, which I did not want--gotta have it my way). I have no experience with IBM. Key is specs, no OEM products, licensed operating system, fast Intel CPU (try to get the latest), I like 10,000 RPM hard drives (in a RAID array suits me) and good ram (CORSAIR, etc). I don't need a good sound card as I use firewire out, so I don't have a spec for that. (I did go with a top shelf graphics card, though, for the photograpy). I'm a little fussy with my puter so I may not be the guy to ask. I'm sure you can get something very suitable for PC audio without spending that much money, in fact, I know you can.
I think Vista is a huge improvement over the prior microsoft os. Must cleaner, faster and I have been using for 2 years and have never blue screened - meaning computer got stuck in an application, needed to be rebooted, etc. I have heard from my IT guys that 7 is much better than Vista, but I haven't played with it yet. I wouldn't think that for PC music, there wouldn't be much of a difference as both do not use the windows Kernal (a big no-no in PC audio), but do not know 7 first hand. Years ago I would be the 1st to install 7 but these days, just leave my PC alone as it runs great. I believe the new PC's come with OS 7 and I wouldn't have an issue with it.
Arj,

One more-from Maudio Manual
IMPORTANT: The FireWire Solo comes with a high-quality six-pin to six-pin FireWire cable. We strongly
suggest you use this cable, or one of equal quality, for optimum audio performance. If your computer is
equipped with a four-pin interface, you will need to use the included four-pin to six-pin FireWire cable.
Note that the FireWire Solo requires a six-pin FireWire connection in order to supply bus power; if you have
a four-pin connection you will need to use the supplied power adapter.
Arj,

Thank YOU for the tps. I just upped my buffer and bypassed mixer as well and soundstage appears deeper. I will do some A/P listening but, so far, think its a go. Think your issue is the cable and/or power supply. Please report back when you change cables.
Arj,

That is very strange. I haven't any issues with smoothness. I am running Vista service pak 2 (32 bit) and using the M Audio drivers, and no issues. I do have a pretty beefed up PC. Maybe the power supply is the issue. I used the power supply when I first got it and didn't like it at all. I haven't heard anything about the MAudio drivers, but than I really didn't look for info on it as it's working very well for me. I'll go through the above posts and see if you advised what os you were using, etc. If I see something worth mentioning, I'll let you know. Not sure if you tried the WASAPI but I keep thinking the power supply may be an issue-just not sure at this point.
Arj,

I just did some poking around. The Compaq PCMCIA card may be an isue as well. I'm assuming device manager doesn't show any issues. I'm not familiar with the technology on the interface but I would speculate, perhaps, a better card may help? I'd hate to have you spend more money, but may be worth a shot. I am also thinking, with that great DAC of yours, you may not need the Monarchy? Or...are you using the dip to upsample? Maybe disengaging (upsampling)that as well-or just taking it out to listen? I only use the DIP cause my MF XDAC3 isn't very top of the line these days, while your DAC is pretty much state of the art. I use spdif - out from the DAC; I see you use the 110 ohm out. I'm searching for a PCMCIA card with a 4 pin out as well, whih would eliminate the power supply.
Thanks, Al. Very good point. Another reason why I think Arj's interface is the issue. I have the TI chip and haven't had a dropout. I couldn't find much on the Compaq interface Arj is using.
Sorry to hear, Arj. I really feel Firewire is the better interface (over usb) but haven't played with it on a laptop/outboard card. Sorry for your experience.
