I have been looking for cartridges online for a while. Whilst I was checking MC/MM cartridges on e-bay, I noticed that the new Ortofon Vivo Blue MC cartridge was actually advertised as a MM cartridge. I advised Analogue Seduction that there was an error in their posting, not expecting anything in return, they kindly e-mailed me back saying thank you for telling them of the error and also offered me a further 10% if I wanted to purchase the cartridge I think that was a great gesture and should be mentioned. Not many people would do that. Fantastic!
