Well the Wyred 4 Sound DAC-1 LE with the Femto clock is $1124. It uses the exact same chip as the Amber, is hand made in California. EJ and crew even build the circuit boards in the Atascadero Ca plant. The units are virtually identical to the DAC-2 which once again won TAS Editor's Choice award. The main difference is that the DAC-2 includes pre-amp functions and remote control, not available in the lower unit.
The Wyred units are also backed with 5 year warranties and are fully balanced. I use the XLR connections to keep my system fully balanced throughout, and oh, I forgot, yes it does do DSD64, DSD128, and DSD256.
The other Lampi, the DSD only model would be the one to consider in my view. I would take the W4S unit over the Amber, but would certainly consider the Euforia model if I were to upgrade since it has the Lampi designed DSD circuit.
Oh, by the way, the Amber only goes up to DSD128. I could not tell for sure on the Euforia, but it seems from their website that it might be topped out at DSD128 also.
"The newest DAC from Lampizator - breaking the price barrier.
AMBER : 1800 Euro for well equipped DAC. The price includes: USB input, PCM up to 32 bit/384 kHz files, DSD 128x and 64 x auto sense and auto switch pcm/dsd and all file sampling rate switching. No manual function to be used. THIS DAC HAS NO SPDIF coaxial input. Toslink is standard spdif input and it is of highest quality, 100% matching S/PDIF or AES/EBU sound quality so it can be used with any transport.
DSD Euforia is exactly the same as Amber, except that Euforia is a DSD-ONLY DAC, without PCM at all. It shares chassis, PSU and analog section with the Amber but it has only DSD filter and USB input. The DSD is our own Fikus design while in the Amber it is an off the shelve Sabre dac chip. Euforia sound quality for DSD is better that Amber in absolute terms, but lack of PCM means that red-book files have to be converted on the fly by the computer. You can use JRiver or Foobar for this and forget about PCM forever."
With any USB to DAC combination I would use the Wyred 4 Sound Recovery unit. Yea, it is that good!
