mcintosh home theater pre-amp tuners.


I have a McIntosh mx132 home theater pre-amp tuner. it's list price was 7k. I see on ebay that many of these, mx130, mx135 and so on doesn't retain their value. is there a reason for this and where doe's mine stand?

only reason i bought the mx 132 is because i don't have funds for a separate pre-amp and tuner. being retired and on a fixed income does'nt help any.
For the price you paid, you did just fine. The only way you would improve your preamp would be to spend a lot more money on a 2 channel unit. The problem with 2 channel preamps now is a lot of people buy a new one to keep up with the DACs codecs because they also use the preamp as a DAC. If you are just running 2 channel analog with your MX132 the preamp bypasses all the processing circuits. 
i am not an audiofile. i'm 65 and bought my first system back in the 4 chanell days which i used all the time from then till 1990 then i took a 10 years vacation from my equipment. in 2000  i did buy a 2205 amp till 2011. then my son gave me his 602 which he bought from audio classics. at that time i used my marantz 4300 as a pre amp tuner. it was always noisy so that's when i bought the mx132. i only use my stereo only once a week. so i'm not really an audiofile!
You do not have to be an audiophile to appreciate good equipment. The MX132 is a huge upgrade from a Marantz 4300 either the 4300 surround receiver, or the classic quad receiver. The gear you have now is better than 99.99% of the systems people listen to music on these days, think a cell phone and ear buds.
hlg3, i did'nt say that my 4 speakers are 4 bose 901 series 2 speakers. i used to visit a mcintosh dealer to look at there products . he told me that he never heard of a mcintosh amp powering these speakers.
