McIntosh Integrated amps - speaker pairing questions

Hello all,

I inherited a bunch of gear and am trying to figure out what to pair with what and which speakers to repair. I know next to nothing about vintage stereo stuff, but I listen to lots of music. The three McIntosh amps I have are all in good working condition (as far as I can tell, but I probably am going to have them serviced):

MAC 1700

MAC 1900

(the balance knob does not work properly, but otherwise good)

MA 6100

The speakers I have to choose from are:
- Large Advents ("The Advent Loudspeaker") - seem to work fine, but bass seems weak
- Baby Advents (Advent/3) - two pairs, though one needs at least reconing and maybe more work
- KLH Model 33
- Fisher XP60-C
- JBL 4312A - needs reconing
- Totem Acoustic Dreamcatcher Monitor - random newer speaker that might work with this vintage gear?

The rooms I am setting up in are:
- Largish living room + open plan kitchen (approx 300 sq feet). This is where I will be listening most.
- Office (120 sq feet) were most of the rest of my listening occurs.
- Basement room (approx 150 sq feet) where I listen to music fairly rarely. Mostly TV.
- Bedroom (140 sq feet)

I have two other vintage amps but am not sure if I should use them for anything:

- Harmon Kardon 330B
- Dynaco Stereo 80

All my music right now is in an iTunes library (everything ripped as lossless to FLAC and converted to ALAC) that I connect to the amps via airport express. But eventually I will probably get a DAC and run wires. Sometime a ways down the road I may also attach a CD player and turntable, but not for quite a while.

Which speakers would folks suggest I pair with which amps and for which rooms? Or should I sell some of this and get other speakers entirely?

Any advice would be appreciated!

The baby's and the large advents should be pretty efficient and I would expect them to sound good with the MAC1900. Did you get the version that has switchable impedance (4 or 8 ohms) or not? I believe the MAC1900 is 55 watts per channel, the MAC1700 is 40 wpc, and the ma6100 is 70 wpc. Try the ma6100 with the large advents to see if they are a better match together.

But honestly, I would just try them out and see what you like best together. Numbers only give part of the picture, and the room and speaker placement will define your limits.
 
The 1900 does not have the impedance switch (neither does the 6100), but all the speakers are 8 ohms.

My first MAC1900 didn't have the impedance switch. I thought it had less oomph, but I never compared the two back to back.

Yes, there are lots of Mcintosh lovers just waiting to help! :)
