Actually it would probably be more correct to say that I am the front man for "Pedja's new DAC", with Pedja being the one behind it.
Pedja and I discussed it's H/L architecture. Once that was agreed, Pedja carried out the L/L design and testing.
It will be released in February 2011 under the name Gramofone HD Digital Music Converter.
I'm not convinced by the current fad for non-oversampling, analogue low-pass filters and obsolete 'NOS' d/a chips.
I can say that IMHO my current CD player / DAC sounds using Analogue Devices AD1955 DACs is better than any I have owned in the past, which contains pretty much every 'generation' of technology used from the Sony CDP-101 onwards, through Phillips 14bitx4 O/S, 16x4 O/S, Bitstream/MASH.
I think the Squeezebox Touch is a breakthrough device, and can be a very, very good digital transport. The SQ potential was validated by a friend who found that there was almost no difference between his Zanden transport and the Touch when fed into his Zanden 5000 Mk 4 DAC, any improvement probably being attributable to use of SP/DIF over the preferred I2S interface.

The problem is that a lot of old multibit players are implemented quite shoddily quite simply because in that day designers didn't know how to properly work with mixed analogue / digital circuits, PCBs had poor ground schemes, shared digital / analogue supplies, horrible output stages etc. Drop in a multibit DAC into a modern circuit & the result is clear.
Hi Neil,
As mentioned above, I have listened quite extensively to what is supposed to be one of the very best implementations of the TDA1541A, as implemented in the Zanden Audio Model 5000 Mk IV with no oversampling. It did have an enjoyable sonic presentation, with plenty of zest, 'get up and go', and good detail retrieval but I also perceived a degree of roughness that was thrown into stark relief compared to the refinement and information retrieval provided by an SME Model 30 (well, it would, wouldn't it?). This was in a very high resolution neutral system that most would consider to be close to a state of the art or true reference system. Certainly in this DAC, the power supply, the output stage, PCB design and component selection is no-compromise and not cost constrained. I think that delta/sigma converters and high oversampling rates don't preclude good performance, and that they also benefit greatly from design attention in all of the areas you mention.
I suppose what I was reacting to the a rash of nostalgic, revisionist reinterpretation of the performance of kit that in it's day didn't really sound that good by modern standards, and the unjustified pumping of second-hand values of these pieces of kit. I was thinking in particular of the Sony CDP-101 that I am very familiar with, having owned one from new. I have read a number of hyperbolic reviews of it's performance, that IMHO are not realistic, without even taking into account it's terrible reliability!.
Regards,
Alex

I had a regulated liner power supply for the Duet built into my Lampizator Dac as the stock SMPS was just too dirty. The Duet receiver was also modded for SPDIF out. Thus it feeds the Lampizator L4 with a cleaner sound and its heavenly. I dont have Maggies though, I have Heil AMT Syrinx.
My amp is not too exotic, it's a NAD c375 BBE with the ROWEN Swiss Power (RSP) upgrade, which takes the Nad up a couple of notches. The RSP upgrade is 35% of the stock price.
Back in the 90`s I thought Delta Sigma players had the most natural midranges and even some image depth (shock horror) when compared to Multibit which could only counterbalance with a tighter bass in comparison.
Just repaired a Helios 1 - deserves classic status in my opinion.
Bluenote Stibbert too - very natural and great soundstage.

A mention for a CD/SACD player I've been using for a couple of months now ~ the Marantz SA KI Pearl Lite.
This produces a smooth, yet detailed sound, with a fluid presentation. I've had quite a few DACs (AS DAX, AN DAC1 & 2, Renaissance RD01, BM1, et al) over the past 1-2 years, yet this player tops them all, IMO.
This has the ability for two digital inputs to the player and has SACD capability. OK, SACD is more or less dead and discs are very expensive, but the sound quality can be significantly improved over CD. Of course, the digital inputs also allow direct comparison between using the SBT as a network palyer and the CD itself ~ but that's for another thread at some stage.
The player is well built, nicely designed and a real pleasure to own. OK, Marantz isn't a chic, boutique manufacturer, but if you can get past brand snobbery then well worth investigating. A great deal of player for not too much money.

I love Marantz KI players, (though I know my mate Dave (DSJR) isn't quite so keen...) and the one I have now was heavily praised by HFW in its time... so I've always lusted after the Pearl/Lite - nice player Simon.
