Someone produced a $16,495 CD player

Even audiophiles are wondering

Luxman is about to release a new high-end SACD/CD player which will set you back $16,495 and sports a MUS-IC BD34301EKV DAC chip.

Luxman America’s press release makes much of the Luxman player’s dual-mono DAC circuit will use a pair of ROHM’s 32-bit Delta-Sigma converters, each boasting an SNR of -130dB.

The audiophile in us loves reading press releases which come from audio companies. 

“The MUS-IC BD34301EKV reflects 28 separate parameters optimised for sound quality, including aspects of circuit design, layout, photomask, wafer production and packaging. For example, to optimize sound quality, selected “bonding” wires that connect the chip to the lead frame are made of copper, while others are made of gold.”

The Luxman player’s dual-mono DAC circuit will use a pair of ROHM’s 32-bit Delta-Sigma converters, each boasting an SNR of -130dB.

“Feeding those DAC chips is Luxman ’s improved LxDTM-i disc transport mechanism that wraps the disc mechanism with aluminium side cheeks and a 5mm steel top plate to combat the twin foes of vibration and resonance. LUXMAN has also reportedly enhanced the disc reading mechanism and added ‘density gradient cast-iron insulator feet’ to the unit’s base to keep shelf-borne resonances at bay.”

But at the end of the day it is all still digital right?

On the back there are a digital inputs to connect to PCs,  network streamers, games consoles and TVs access can access the internal DAC circuit via 1 x coaxial or 2 x TOSLINK inputs that top out with PCM at 24bit/192kHz whilst the USB input extends PCM support to 32bit/768kHz and brings DSD512 into the picture. All four digital inputs are MQA-compatible.

Along with the USB’s usual isochronous data transfer mode, Luxman has specified their BulkPET technology that allows USB audio data to be transferred from host to DAC with USB’s Bulk mode (as used by a hard drive or a printer), thus bringing with it error-correction that doesn’t show up in isochronous mode.

According to Luxman America’s press release, BulkPet “uses data packaging and delivery to the converter, easing the processing load for both the host CPU and the device CPU. This, in turn, reduces the workload between reading and reproduction, enhancing playback stability and improving sound quality”.

So anything else for the money?

The D-10X also sees the debut of Luxman ’s ODNF-u ‘Only Distortion Negative Feedback (ultimate)’ circuit that nurses the analogue signal from the DAC chip to ‘gold-plated-alloy’ RCA outputs and balanced Neutrik XLR sockets.

“This fully balanced configuration maximises error detection accuracy, for greater musical expression across the audio band. Tailored, gradual 1st order filter x 3 band processing achieves a natural waveform without the need for conventional output filters.”

The D-10X also features an oversized power supply with large filter capacitors and fed by a transformer that’s 27 percent bigger than the one found in Luxman's previous flagship; a loop-less chassis designed to shield against digital noise; printed circuit boards with “gently curved wiring patterns” that reportedly promote signal flow; 100 μm copper foil signal traces and gold-plated connections that seek to minimize stray capacitance; a brushed aluminium finish.

It will be in the shops in August and no matter how much gold is in the thing, I can't see it making difference, but I have not run CDs in my rig for nearly a decade.
