Want to upgrade to new DMA

655 Views 5 Replies 4 Participants Last post by  ecorob
I have been using an Omnifi DMS1 with a D-Link 802.11b USB adapter for about two years to stream music from my PC to my home theater/audio system. I have recently upgraded my recv'r (Denon 3805) and installed a full 7.1 speaker system (variety of Boston Acoustics speakers.) I love the convenience of the DMA (no discs, full access to everything) BUT I'm finding my digital music quality could be better now that I have a better system.

A few questions I'm hoping some experienced digital music listeners can help with:

- What DMA's offer the best audio quality for music? Other than looking for optical audio outs, what should I look for?

- What do I need to do with my audio files on my PC to get better quality? I ripped all my CDs to my PC using MusicMatch (most of them ripped about 18months ago) Sound is OK, but not quite as good as direct from the CD player. Is there a better way?

- I listen to Rhapsody (my Omnifi handles Rhaposdy), but the sound quality is below the music I've ripped to my PC, most likely due to internet streaming. Are there alternative streaming music subscriptions services with better audio quality?

- I listen to 5.1 DTS music in home (hope to upgrade to DVD Audio player soon to match the DVD Audio capability that came standard in my Acura TL) Do any of the DMAs allow streaming of DVD Audio or DTS music from a PC?

I am in the process of researching this as well because I want to buy one soon. Based on what I've read, I may be able to answer some of your questions:

1 - From what I've read, the Cambridge Audio Azur 640H provides the best audio quality for music. In fact, it's so good you'll want to use the analog outputs instead of the optical output. This way you can take advantage of the Aazur's superior DACs.

2 - You will need to re-rip your CDs to get better audio quality. If you plan on getting a DMA with a modest hard drive, I would recommend a lossless format. If you plan on using a large hard drive....try ripping them uncompressed.

3 - I can't answer the internet radio question because that feature never really interested me.

4 - I no of no digital media servers that can output 5.1. Maybe the more expensive ones do, like the ReQuest line? If that is a concern of yours, you may want to get a digital video server as I am sure that they would also support audio and 5.1 audio.

THANKS! Lossless???-- any leads/links for good software for lossless or uncompressed ripping?

I just did some search as well on this topic. I didn't realize that "CD quality" as labled on many services, is sometimes 64kbps or less.

I also just looked at the set up for my MusicMatch jukebox software. I've been ripping at 128kbps and I now see that I can select WAV format (which is 1100kpbs+ or use MP3 at up to 320kbps recording. Is 320kpbs equivalent to "lossless?" I wondering how much is enough...

The cambridge audio box looks interesting, but I'd still prefer to manage my music on my PC and then use a less expensive DMA to stream to the listening room-- I guess one issue will be that streaming might limit the bit rate, but I would think with a wired Ethernet connection the quality would be good, but WiFi may drop/cut out at the higher rates...

For anyone else who is new to this topic, I found this link which gives a good description of the various formats for digital music:


So, it appears my OmniFi DMS1 will support 312kbps MP3 as the highest quality format, but it won't support WAV or other lossless formats.

I plan to experiement with re-ripping some CDs at 312Kbps and see how it compares to playing directly from the CD player.

I'm interested in other opinions as to "how much is enough" on bit rates and whether loss-less is noticeable and meaningful improvement in sound quality.

I'd like to think that 312Kbps is sufficient so that on music library will be useful for home audio playback on my main soundsystem as well as compatible with MP3 players like iPod. (I'm assuming that if you go to loss less formats, the storage becomes unwieldy even if an iPod support lossless.)

If 312kbps is noticeably inferior to actual CD playback, I think I'll try a Roku Soundbridge and rip 25 or so of my favorite CDs to WAV format.

I read a number of years ago that one of the inventors of the CD audio standard maintained that the 'normal' human ear would not be able to resolve differences in audio quality above 200 kbps. Higher bitrates are only required to fully resolve the audio spectrum up to 20kHz and higher. So if you are something like 12 years old, you might want to go with a higher rate. If you are 50 or older, like some of us :), anything higher than 192 kbps will probably make no difference (at least to me). Hope this helps. I'm sorry that I cannot find that article as it explains all this in detail.

Has anyone tried the new Simplecenter 4 software and got it to work on their Omnifi
