@larryi so what makes you think that the rep, like the one for Miyajima, who is ok with this policy...of return, is good;and yet it’s also ok for others not to be. Thereby, foisting the risk back onto the consumer. The Miyajima dealer is IMO, offering a true service to their customer..the others..well not so much.
Sorry, but the analogy of the restaurant makes no sense to me. Plus, there are numerous restauarants who in fact do offer a taste of the food that they serve, prior to order.
While, I agree that listening to a specific cartridge in the dealers system would be a good start, it really isn’t anything more than a data point in regards to what the cartridge might sound like in your own system. You are doing nothing more than assuming what you started about Koetsu’s SQ would apply, if one was inserted into your own system and room. I state this since you admit that you haven’t actually listened to one of these cartridges in your own system. That assumption may prove to be correct, but you will never know until you have taken that action.
If the results are 180% away from what you expected, you would have an unpleasant surprise, no??
