My $50 DAC

Urizen... very interesting observation regarding the Toshiba as a transport!

I'd be curious to know if that behaviour is specific to this transport/DAC combination... have you tried that Toshiba with other external DACs?

No, I haven't. I have a feeling that feeding the Entech with an already upsampled signal is not the best thing to do. It needs a redbook signal.

A tube buffer behind the Toshiba, which I have tried, sounds good.
 
30 Day Status Report on the $50 DAC

Today marks one month of “fairly regular usage” so, according to the manual, the DAC has burned-in and reached optimal levels of performance. Throughout the month , I left the analog outputs of the CD/DVD player connected so that I could switch back and forth between the internal DAC (24bit/96 audio DAC according to Njörðr Nóatún) and the 20bit Entech 203.2.

There was an immediate improvement in CD sound quality with the Entech. The difference became much more pronounced after the initial 24 hour burn-in, with gradual and continuing improvement as time passed. In particular, the highs showed the most improvement over the period. Initially, they were a bit metallic, almost brassy. Over the month, they opened up, bringing additional depth to the sound stage. The mids were very good from the start, but have opened up as well. A little change in bass is noted, becoming more musical over time.

I set out to really listen today with a selection of favorite music: Robert Randolph and the Family Band’s Live at the Wetlands; Madreblu’s Necessità; Tutto Fellini (Nino Rota’s film soundtracks); and Nucleus’s Elastic Rock. On every single track, the Entech performed far, far better than the internal DAC.

One of the most striking improvements was noted on Madreblu’s album. With the external DAC Raffaella Destefano’s silky vocals purr from the speakers. Live at the Wetlands charges out into the room with all the energy and image of the live performance. Nino Rota’s work for Fellini has always been a self-indulgence and, with the DAC there is so much more depth, clarity and separation of the individual instruments that I am receiving threats regarding its frequency of play. Quite possibly my favorite album, Nucleus’s Elastic Rock has been a revelation. I was able to purchase a limited edition (2500) re-mastered CD of this album. I have a vinyl collection of Nucleus going back to 1970, which includes an import copy of Elastic Rock. For the first time on my system, I now have a CD that actually sounds as good as ( and maybe, just maybe a little better than) the vinyl.

There is simply no real comparison between the sound quality produced with the 20-bit Entech and that produced with the 24-bit internal DAC of the Panasonic. When I switch directly between the two, there is a loss of at least 60% of the bass, highs, clarity and imaging when the internal DAC is used. I’d have to spend lot more than $50 buying a quality dedicated CD player to match what the Entech has done for my system.
 
Well I finally got my system hooked up with the number cruncher in the loop.

I do not have a well trained ear for this stuff, and have not listened to a wide range of gear. But I do notice a pretty significant increase in sound quality with the new DAC, even though I'm pretty sure my CDP is a couple years newer than the DAC.

I guess I would have to say the sound is overall smoother and more detailed, less harsh.

I just recently read a review of an Entech that was included in an auction for one. The reviewer states that the Entech runs 3db hotter than other sources making it "sound" better due to it being louder. He goes on to say that, to properly compare it to other sources, one needs to match the outputs of the components.

Well, 24 hours have passed and the DAC is HUMMIN' There is a soundstage and articulation present in my system for CD's that just was never there before! One thing I have noticed is that, after burn-in, the DAC does seem to add gain to the circuit. [/QUOTE]

The amplification difference was quite apparent from the initial hook up.

I currently have the Entech hooked up, through my pre, so that I can A/B against the output from my Ah! Njoe Tjoeb 4000, with upsampler, and the Entech, with the push of a button. The Ah! has a 2.5V output. The level sounds the same when switching back and forth. The Entech manual states a 2.5V output, also.
 
I just couldn't take it anymore and had to find out what all the hype is about with the Entech 203.2. Mine should be here early next week. :guitar:

Me too. I just in the past year discovered how great a budget dvd player sounds compared to the old 1 bit dac. I am hoping this will take me a step farther.

ditto. I'll be doing an a/b against my Adcom 600.
 
Now I'm Intrigued. Sony Discman circa 1990!

I currently use a Sony Discman circa 1990 That I found in a desk drawer! It is plugged into my Mcintosh c28 pre amp which is plugged into my Mcintosh mc2505 amp which is then plugged into a pair of Klipsch Heresy's type I (The Mcintosh's and Heresy's have been serviced recently). It actially sounds decent. although i need an upgrade.
 
A prerequisiste for any DAC is that the CD player must support digital outputs... whether through an optical or coax (RCA) connection.

If you are asking whether a DAC will connect to the standard stereo RCA outputs... the answer is no. Those are analog outputs.

Yes... that is exactly the point.

The DAC's primary purpose is to do a better job of digital-to-analog conversion (hence the name) than the built-in circuits in a typical CD player. Usually the analog side of the system is upgraded as well.
 
From other another poster on this thread, I learned that my DVD/CD player"s internal DAC is 24-bit, higher than the 20-bit Entech. However, the Entech simply blows the internal DAC away in terms of the quality of sound produced. I would think that the results may vary widely, depending upon the specific build quality of your internal DAC (sounds like a pharmaceutical commercial). :scratch2:
 
The bitrate of the DAC is only one of many factors to consider.

The design of the analog output components could make a significant difference I imagine..... that's why you see some DACs with tubes in them.
