What Would Be A Good Price For These Speakers, Amp, and Turntable?

[Mezeno]

There is an estate sale coming up in my area that has the following hifi that will be available:
Pair of Martin Logan - SL3 Hybrid Ribbon Speakers
Audio Research D130 Amplifier
Olufsen Beosound 4000 Overture

I don't know what the price of these items will be, but they appear to be mint. I have done some research, but I am hoping that others who may have had any of these pieces might provide me insight into what they would value them at. I will only by pieces that are a steal or really good deal, as I am happy with my current setup at home and want to be able to easily sell these if they are not better than what I currently have. My current set up is AR-XA turntable, Adcom GFA-545 II, Adcom GTP-400 Tuner/Preamp, Adcom GCD-575 CD Player, and Vienna Acoustics Schoneberg Speakers.

Thanks for any help and/or insight.

I would bet that estate company has done their research. Looks like a pretty high end estate. I would expect to see them priced at or above market value.

If they did their research it wasn't a very good job. Martin-Logans are ESLs, not ribbons.

I agree. It looks funny. They even list an NAD preamp with no info.
