I made a separate topic
not knowing this huge topic was here, looks like a lot of experts are here!
My situation is summarized as follows:
source: TV optical out (for streaming music, youtube, movies, ...)
DAC: optical to analog
preamp: currently Rotel RC 1070, analog in and out
power amps: lots of them, all balanced currently but might move to some unbalanced for the mids and highs on my speaker
speakers: pair of Infinity Renaissance 90 and a pair of passive subwoofers (2 x LAB12C and a 18" PR
sub crossover: I was going to use my old miniDSP 2x4 but after reading, I would replace it with the HD version
I am thinking of using the 2x4HD as the only preamp, so TV - 2x4HD - power amps - speakers and subs. I am also planning on bi-amping my infinity speakers, so use Y splitters after the 2x4HD. In attachment a schematic overview of what I would like to do.
I already received some answers in the other thread but I wonder if:
- It is a good idea to use the 2x4HD as a preamp or it makes sense to put the preamp still in the flow, which would introduce more DAC and ADC into the flow
- There is a way to put a volume knob on the 2x4HD?
- using splitters to bi-amp is a good way to go?
- There are other alternatives to the mini dsp which would do what I want, equalize the subs, crossover for subs and volume control? This within the 'miniDSP' product line but also other brands. Possibly combining some kit boards in a DIY housing. Would a Crown XTI-4002 for example be a good alternative, it has DSP for my subs and enough power to feed them, but I think the DSP in the 2x4HD is more powerfull? Or another power amp with DSP in? I have already a lot of power amps so would need to sell some in that case...
