MHDT Laboratory Pagoda Balanced DAC

The LAST MHDT Pagoda Balanced in Silver ever produced - they are still producing it in black. Purchased 2 months ago from Linear Tube Audio with upgraded Western Electric 2C51 tubes ($160). 
This has balanced and unbalanced outputs, but uses 2 DAC chips per channel in balanced mode. This is a NOS Tube DAC but has extension similar to DS DACS while keeping the smooth NOS DAC characteristics. In addition, this plays up to 192/24 in NOS, not just 44.1/16. It does not convert down either, the included DAC chip actually plays 192/24 in NOS. 
Now with J grade PCM1704 This is a DAC mainly designed for audiophile and studio guys or who need long distance connection by XLR. The balanced version was designed to be a real balanced structure; i.e. two Pagoda, one in positive sig and one negative. Total 4 PCM1704 DAC chips were used, each chip is independent for right and left as well as positive and negative signals. In RCA connection, this DAC is the same as original Pagoda DAC. In XLR connection, you get double amplitude signal out. CS8416 digital input with non-oversampling structure. This is traditional DAC, it cannot decode HDCD signal. The digital signal accepted is based on the capability of CS8416 digital receiver, which means the max: 192KHz 24bits input Spdif format. USB input: Up to 96kHz/ 192KHz (*) 24bits then convert to spdif then to CS8416 no over-sampling, no digital filter Utilize legendary R-2R multi-bits Burr Brown PCM1704 - J grade (24 bits) DAC chip. No differential phase shift in both channels. More detailed yet natural and musical sounding. Metal case, with silk brushing aluminum plates , acrylic front panel. Tube buffered output, tube installed GE5670 Tubes can be used: 5670, 2C51, 396A, 6385, 6386, 6CC42, 6854, 6N3P,6N26P, 6854, CV2575, CV4013, CV5894, CV8247, CV2381 115/230V power supply selectable from internal PCB jump pins setting SPECIFICATIONS 1 x AES/EBU, 1 x USB input, 2 x Coaxial input (1 RCA , 1 BNC), 1 x Toslink optic input.
