Thanks guys -- to answer a couple of the questions:
-- why these 2 models?
-- upgrade your electronics first?
I am not an audiophile, I just enjoy music and inherited this system from my dad (who was an audiophile way back when): MC2720 amp (my replacement to 2100 from the '70s), preamp (C28) and Tuner (MR77) Kyocera DVD and Bluesound dac -- current speakers are MC XD-715 - so a mix of '70s and 'late '80s/early 90's (other than DAC))
system will go to a much larger space so I am thinking i need a larger sound and that speakers (which are light even for current bedroom setup) would be the thing to change to most economically achieve that?
i listed the 2 that I did because they appeared to be the "best" for sale in the used market driving distance to me in my price range -- i am not looking to backward upgrade my entire system into the speakers that I choose - but rather would like to figure out what would best complement what I have and project more sound
it sounds like super high end/modern (or the label you wish) used speakers like the ones mentioned (which are modern compared to '70s electronics but both are 15 to 20 yr old) are "too good" for my electronics? -- so what should I be looking for ... some 10-15 year old Khorns? at the end of the day it always seemed smarter buying used in a premium market b/c there is such a markup for new...kind of like the value that drops off a car the moment it is titled one time even if it goes no miles
on the other hand, technology changes and maybe today's $5K speaker does what Wilsons' WP7 $22K speaker did from 15 years ago? I have no idea...that's why i am asking...................
