ARRIVED: new Rega DAC - Page 6

post #76 of 517
Thread Starter 

Yes - not subtle to my ear.

 

Probably not - USB sounded better to me than toslink directly out of my Mac Mini

 

Yes - Evo is way better than the toslink S/PDIF from my Mac.

-Will USB on the Rega Dac sound worse than being fed spdif through a cheap onboard sound card? 

 

-Will the sound of the Rega Dac be improved by the hiface EVO compared to using a cheap onboard spdif output?

 

If questions 2 is also yes and question 3 is no, then I know I can easily live with the Rega Dac as it can handle any digital source and manage the jitter so I don't have to have premium digital transports to get the great sound out of the unit.  Being able to get the same great sound whether being fed by a Saturn, a hiface EVO, or the crappiest spdif computer output I will ever encounter...that would make the lack of async-usb acceptable for me.  However...what is the answer for question 2 and 3?

Hmm, too bad.  I guess it is still more sensitive to jitter than I'd want.  Still, I really like the Saturn so I'm pretty sure I'll like this especially if I can feed it with something like the Halide Bridge.  I guess the benefit of a good CD player is the entire chain from source media to analog out is self contained in one unit.  No worry about transport jitter, digital cable jitter, spdif input/output circuit jitter,etc.  I'm guessing the Rega DAC could sound better than the saturn if it was fed with as good or better transport than the saturn.  But if fed by any random optical out from a computer, I'm guessing it's not going to reach that level of quality.

 

I'm definitely still very interested.  Just how bad is it fed with the worst sounding source you have, the Mac Mini?  Still better than other DACs you've heard?

Rega DAC 

Rega is fresh in the DAC industry. Nevertheless, listening to the fresh Rega DAC is a superb sound experience. 
 

Geir Nordby Journalist 11. February 2011, "Lyd og Bilde", Norway

 
Regas digital converter has two coaxial and two optical digital inputs in addition to USB. Thus, you get connected to the vast majority of digital audio sources. It accepts high-resolution music signals from anything other than USB, which takes only 16-bit 44.1 to 48 kHz. In the USB input Rega has emphasized suppressing noise that propagates from the computer's power supply, making it so that it sonically does not matter if the computer is on battery or AC power. Two Wolfson DAC chips is decoding the digital signal, and the user has five different filter settings on the front panel to choose from, which colors the sound a bit differently. We prefer the filter setting 1 

Sound Quality 
Although the converter does not support 24-bit audio files from your computer, it sounds very good with USB. The music is rendered clean and open, with a rhythmic bass.Female Voices are airy while centered in the middle of the soundstage, and  we are presented with a huge soundscape. With 16-bit audio it is the among the very best DACs in this group test, maybe even better than Electrocompaniet and Bel Canto. If you run 24-bit sound from your computer, Bel Canto sounds better. Still, Rega has no immediate weaknesses, other than that it does utilize the full dynamic range of 24-bit audio files (IN USB MODE, red)Using the coaxial transmission from Blu-ray with 24-bit PCM out, the Rega DAC presents an even bigger sound, and it is very good room for the instruments in an orchestra. There is still little left to Bel Canto and Electrcocompaniet in this respect, but not much! If you do not need variable level adjustment by remote control, it is only the most extreme high-end enthusiasts that'll need something better than the Rega.

Nice find!  Google Chrome auto translate web pages so you can read the whole article more easily.

Well after reading that whole comparison test, I don't really know what to make of it.  Some cheaper DACs were rated higher in sound, but I wonder if the Rega was only tested through it's USB port.  It was not clear enough how each one was hooked up for the resulting ratings.

 

The jitter results also did not look that good, but again it might have been measured through USB only.  I was really surprised at how bad some of the asynchronous DACs performed in this regard though.

The back of the unit has 1 RCA S/PDIF OUTPUT and 1 toslink OUTPUT as well.

 

I'm just wondering if both those outputs are always active with whichever input source you are using.  Thus making it possible to use this unit as a USB to SPDIF converter.

All DAC's are rated according to price - so it is a value/performance rating. 

 

The Rega was, however, "Especially Recommended".

 

And remember - sound is a matter of taste :-)

I'll answer this myself since I just got this DAC.  Yes, you select any input, and the two spdif outputs are outputting the stream of the selected input.  This lets you daisy chain DACs together for easy comparison.  I wonder if the Rega actually reduces jitter on it's output compared to what was input. 

 

In any case, I fed the Rega with my Cambridge Audio D500se, and used the Rega digital outputs to feed a DacMagic and Nuforce HDP.  It is clear the Rega DAC is in another league compared to the other 3 sources.  All 4 were simultaneously playing and I could easily switch between any of them on my receiver.  This was with only 3 days on the Rega DAC, I'm hoping things improve even further with more break-in time.  Already it is very impressive.

 

Strange, the website with the review has the links not working.  I wonder what happened to it.

Picked up my Rega DAC in silver today. Just running it in but sounds great so far. It's not supplanting my current CD player but rather is being used with my Mac. Anyone know what I need to do (if anything) to get the best sound out of my iMac? I'm using an optical cable to send the data.

Would be nice with a comparison between your Densen B-400XS and the Rega DAC   :-))

Optical via your Mac is probably the lowest grade connection. I'm sure you'll hear an improvement via USB.

 

If you ever got around to connecting it via a USB to SPDIF converter, it might supplant your Densen!

 

I'm considering picking up the Rega myself.

What?

 

Pretty sure it\s the other way around.

USB to S/PDIF, huh? Anyone got a link to good quality converters? Also, is iTunes a good program to use sound quality wise?
