If it’s getting up there in price, I would think there would need to be an understanding that you would be purchasing something from the brick and mortar at the end of your trial. I mean, a pair of used bookshelf speakers? No problem. I’ve had a decent pair from our local place (really nice guy with a full retail and repair shop etc.) to try out, liked them and bought them. Then he let me try a used subwoofer for several weeks, but instead I wanted something different - he helped find me a nice used Rel even when I was willing to pay new). Saved me SO much money and I love this sub). But this is a major investment. Both sides of this transaction is kinda crucial.
If you’ve built a relationship, shouldn’t be an issue. But if you’ve never purchased from them - and/or a MAJOR purchase - there’s a bit of honor and due diligence to consider. I bet if you have a good in person sit down talk (rare these days) he’d be willing to set something up for you. But maybe go in expecting a down payment or good faith deposit toward something that will work for your space. Chances are, he’d let you try more than the DeVore’s? Although, you’ll probably love them from what I’ve heard about them.
Also, bring some pics of your room/listening area/equipment/setup. Maybe they’ll have some great suggestions on pairing if you’re open to options.
Best wishes, hope you end up with some holiday time DeVores!
