Design features: 1.The new DAC uses BB incumbent top-DAC PCM1792, differential treatment, to effectively improve the signal to noise ratio and improve the details of music to restore the slightest will now 2.Precision reference by the way high-speed op amps expansion flow regulated power supply for the DAC, and further improve the sound quality 3.Use quality SMD Film Chip Capacitors, reducing the loss of quality 4.POP sound elimination circuit at the cost of using the industry's smallest relays, eliminating the very thorough 5.Master, amp and DAC with 4 shelves large area paved, greatly reducing signal interference, while ensuring power supply part of the low-resistance 6.Master use shielded box Shielded master complete, optimized alignment, digital simulation point grounding to eliminate the digital part of the noise 7.All units separate power amp section uses Ti ultra low noise regulator 8.The new amp board, optimize the layout, use the classic AD797 op amp.

Location? MA8 is a new version of MA series, the pursuit of low cost and high quality, so that more people, especially the early burn ownership, but also enrich MA9 professional user configuration. Judging from the DAC, MA9 high price because of the use of the PCM1704, MA8 technique using sigma-deta new DAC, dramatically reducing the cost, this is an important reason MA8 cost reduction, but at the crucial part, but also a little ambiguity, still keeping replaceable modules, rugged aluminum body, independent dual power supply design.
