Q: We are planning to use the unit to follow the digital output of the DEQX crossover unit. This requires 6 channels of DAC, volume control on all six channels synchronized, and the cleanest IV stage that will drive fairly long cables to the AMPs and Speakers. How best to get volume control on six channels synchronized?

Can you use the Joshua Tree Stepped attenuator to do this? How closely tracked are the 1% resistors on the unit? Have you ever used the .1% Vishay resistors on an array?

Is it possible to have three Buffalo 32 units and digitally control the volume on all three in a synchronized way on the boards as they are shipped?

Any recommendation about an external power supply for the three Buffalo 32 boards?

Can you supply modest quantities, ie. 3 to 12 Buffalo 32s?
