The only thing in my system so unique that I consider irreplaceable are my Ohm Walsh speakers. If Harmon buying the company were needed to keep it alive so be it. It’s a very small privately owned company with limited production capabilities so would actually be interesting to see what a large company like Harmon might be able to do. Regardless, I will be hanging on to the Ohms I have for the foreseeable future.
I also own gear from Cambridge Audio, Class D Audio, Schitt, Linn, Electrocompaniet, Denon, Rega, Polk, KEF, Sonus Faber, Fosi, Yamaha, Bel Canto, Boston Acoustics, Dual, Goldring.
