I do not plan to be close by in near future but will bear your proposal in mind. If you will visit Mexico i would suggest you the same.
As i told you, i will let you know about my impressions on Cherry Megaschino and Cherry DAC with volume control once i will have them. Earlier i have ordered a more moderate Cherry DAC 1 tb which gives a pleasant tube -like sound. I have bough a demo one for about 400$ and it sounds not much worse than $7000 reymio dap 777 thought it has a single input, as one i have ordered recently.
I remain curious to audition your d sonic monoblocks.
