Need Help identifying late husbands Stereo components Infinity Beta speakers

Dear HIfiman5, please do write down a detailed list and directions. My husband taught me how to turn on the home theater, but not where to plug in an iPod on the surround unit.  He was a computer engineer, and worked his magic to create sound for us to enjoy.  he died unexpectedly from an aortic aneurysm. He had a stressful day at work. He called me and asked me to turn on the preamp. Came home and went to decompress listening to Claus Schulze Dresden performance part 4. His suit coat is still on the chair in front of his Stereo. He died in his chair, listening to a favorite piece of music. While I appreciate the fact he passed without pain in his Audiophile space, I can not bear to enter the lower level, seeing the speakers along the wall. His sound panels designed to eliminate the echo. This is another reason why we have decided to sell. 
Thank you all for your help. It is truly appreciated.

Sorry for the late entry, but a fellow on ebay that goes by "magicmarksy" may be able to help you with identifying the specific model of Infinity speakers, their value, how to verify condition, current market demand, etc. He may even be interested in buying them.

A good friend of mine talked with him extensively and even visited his home when considering the purchase of vintage Infinities. "Dr. Mark" rebuilds, modifies, and upgrades these speakers perpetually. The dude knows his Infinities.

Very, very sorry to hear of your loss. I know what it is like.

Hi audiophilewidow

...I believe that the posts here which suggested you contact a reputable dealer who handles used gear is *your* best choice for multiple reasons, avoiding unknown visitors included. 

Another vote for the Music Room in Broomfield CO.  I have both purchased and sold good used gear to them and they are first rate.  They do a lot of estate liquidation.

Hello and condolances...  hopefully things improve for you folks sooner than later.  I am in your immediate area and would be interested in the speakers.  Maybe more.  When you feel up to having someone come by to see what is what please let me know.  Again, sorry for your loss.
