Click to expand I don't see how it could be otherwise. I hope we agree that any cheapo transport can read the digital data correctly ie will get read as Given that, the only issue is jitter. The RAM buffer is then used as the source. This certainly makes it transport independent and any jitter there is would be what was introduced between the RAM buffer and the actual DAC chip none I would guess. Taken to admittedly ridiculous extremes a RAM buffer DAC could read the entire CD into memory first and then play it back with the transport switchd off.
The digital data stored in memory would be identical regardless of the transport and at the point the transport would be the RAM buffer itself. The DAC64 is just doing this process on a streaming basis but the results should be the same. K Do you have either of the players you mentioned, or are they a shortlist for a future purchase? Alternatively, if you plan to invest futher funds at a later date then a top notch DAC now would be a good investment with an upgrade to a dedicated transport later on.
You might want to keep an eye on the Classified's section of the Hi-Fi World magazine, bargains do occasionally pop up. If you ever see one of these: www. I think much of the argument has been done already and is in here if you can separate the wheat from the chaff, good luck!!

Originally posted by michaelab I agree that the Tag DAC20 is not as good as that, and it's PLL cannot eliminate jitter totally but they do a very good job. Gary, I have both the transports that I posted initially.
The reason that I was thinking of the DAC was exactly as you stated - I could upgrade the procesing side first and invest in a good transport later. Apparently, the Perpetual Technologies P1A reduces jitter and is meant to compensate for the shortcomings of the transport. Does a one-box solution avoid the problem of signal degradation between transport and DAC?

What we are essentially describing is a computer. In that sense DACs are as alive and well as ever, it's just that they're now just part of an AV processor that does a lot more. Hey Katana, your query whether Int. A re-clocked, low jitter, transformer coupled, co-axial and optical digital output makes it possible to fully realise the potential of high-end stand alone DAC, provided the correct type of interconnect is used. When it comes to transports you should be looking at the best connection type that you feel is adequate for your needs.
Good thread dudes!! Originally posted by michaelab Well, they are actually. I will investigate the Trichord upgrades if they're not too pricey. I'm almost tempted to get one just to check it out. Sounds like a great product for the HTPC guys.
At this stage, a new type of algorithm was developed — the WTA filter. This was designed to minimise transient timing errors from the outset, thereby reducing the need for extremely long tap lengths. The WTA algorithm was a success — a tap WTA filter sounded better than all other conventional filters, even with taps. WTA filters still benefit from long tap lengths; there is a large difference going from taps to taps.
The new Chord products using WTA filters all start with taps. Pulse Array as a DAC technology has been universally praised for its outstanding natural sound quality. The fourth generation builds on this success; it employs 64 bit, 7th order noise shaping; times oversampling rates and improved pulse width modulated elements. These refinements give much better measured performance; better detail resolution with a smoother more focused sound quality.
All filters generate higher output bit data widths — for example bit input multiplied by bit coefficient generates a bit output. All conventional filters truncate the output by discarding bits — however, this discarding may lose information.
By using a bit filter and DAC architecture, there is no possibility of degrading the sound quality. The new chip has two major benefits — all digital data extraction and a RAM buffer a RAM buffer sequentially takes in all the data, re-times, it then sends it out.
