Inherited 21 piece of vintage McIntosh and need help building a system

1-start with your favourite music source; vinyl, cd, radio
2-decide how much space you have for listening
3-I would keep the mac speakers and sell the utahs
4-keep the mr74 tuner--at least until you decide if you will listen to fm radio.  Sell the mr 67 and mr 71 and mx 112
5-keep the 2 c 20's and sell the 2 c8's and the c 28
6- sell the 2200, 2002, 1700, 1900
7-keep the mc 60's and the mc 240 and you will be able to switch these later for listening comparison.
8-sell the ma 5100, mc 250, sansui, dynaco and HK
9-keep the linn and sell the pioneer
10- Now comes the most important recommendation:
       USE the profits from the sales to have the mc 60's , mc 240, and the mr 74 to have the Mac factory upgrade all of these--and hopefully you have the original boxes they all came in as those boxes are worth their weight in gold!!!@
12-When that is done, you will have a system of the highest quality and maybe some cash left to buy a mac cd player and maybe some really good interconnects as well as speaker cables.
13-finally- you could order a set of caps to upgrade the speaker crossovers and have someone in Boise area solder them in.
Some here will disagree with my all-tube selections but wou cannot go wrong with this assessment

this is a correction to my last post:  keep the mr 71 and sell the mr 74.

you may have to go to portland or bend or salt lake city for upgrade help

The absolute best place  for the Mac 60's is my living room . Sorry for your loss . An audiophile friend of mine runs two systems , and each of his children have a system to learn from . Vintage tuners are always in need of an alingement amongst other things . But the amps and pre amps that you have are nice . Find a local Mac Daddy to advise you and can continue an American Legecy , your uncle will be smiling from Heaven 😊.

The folks on audiokarma.org will be very happy to help you sort things out, especially in the McIntosh forum....
