FWIW, since I am replacing everything that was in my prime system with 'reasonable' SOTA compnents, I am expecting to drop 50-65K. I am still pondering speaker choice and final amplification and processor choice but it will be in that range. I have a delightfully compliant wife who indulges my 'addiction' mostly because she benefits from whatever I choose because its freely shared. I'm expecting that sum to give my aging ears and eyes as good a presentation of music or movies as I can discern. Could I possibly do better? Possibly, but I have one shot at this due to the situation so we are going for conservative or proven new innovations in our component selection. This will be my last hurrah and I am determined to get it as close to perfection as I reasonably can on the first pass, since the first pass is gonna largely be the only pass I will get. Long term satisfaction and stable top-shelf performance is the goal here. I fully expect to make a few mistakes in my selection and fixing those will be costly. Its just how it is.
The secondary system will be considerably less money and probably feature a completely different approach. Variety is the spice of life especially in A/V gear. I am guessing this will be approaching 25k
My office system is likely to be 2 channel only and I have already acquired that equipment for the most part. I'll end up with about 8-10k in this one.
The Primary system will represent the best I can do for my situation and so lets set that at 100%. The secondary A/V system at 25k will be every bit 90% of the primary though with a slightly different flavor.
Finally the bedroom system is set at 80% of the primary. I expect to have roughly 12K in it when I am done.
Bear in mind this is buying all components new, TVs and all the rest.
