  1. Reposting from HQPlayer thread as suggested: I am slowly piecing together a plan for a specific ROON / HQP machine. I don't want to have to do this too often, so I want to make the PC somewhat future-proof (for the next few years at least I'm hoping). I am aiming to ditch my old DEQX processor and replace it with a digital crossover plus room correction enabled in HQP. So I need power to convolve multichannel audio and resample (possibly to DSD) which will then be sent to a NAA. By my reading, a lot of firepower will be needed for such extensive processing - Miska's post over at the HQP thread suggested N*2+2 physical compute cores (N=number of channels), then max out clock speed. Cost isn't a big issue - as long as it doesn't end up costing more than the alternative, which is a new DEQX unit (~$6500 USD). Building the PC isn't too much trouble for me, but happy for any advice regarding this (being a Mac guy usually). I was thinking of a dual Xeon CPU machine: - motherboard something like the ASUS Z10PE-D8 WS. It is expensive but should do the job, although many features I probably will never use (should I look at other options?) - for CPU's - I am unclear about whether to focus on physical core number or clock speed. The options would be (a) Dual high speed 8 core CPUs like the E5-2667v3 (3.2GHz) - 135W TDP so heat might be an issue (b) Dual slower 12 core CPUs like E5-2670v3 (2.3GHz) - 120W TDP. Similar processing power in total to (a) probably © Dual E5-2650v3 10 core CPUs - 2.3GHz and 105W TDP. This option is probably the best performance/price option of all that I have costed out so far (still very expensive overall though), but probably a touch less processing power compared to (a) and (b). - I haven't factored in a GPU for CUDA offload as yet, but happy to use as required - probably a minimal OS on an m.2 card, plus other standard requirements- DDR4 ECC RAM, etc. Any informed advice about which way to go would be appreciated! Cheers Scott

    Thanks Solstice380 and ted_b, I will repost on the other thread. I do know that thread well, but there is little discussion about dual CPU machines, but hopefully it will encourage some. I posted here in reply to Miska's very specific CPU core selection algorithm.
