Would you rent a $14,000 DAC for $75 per day?

Camera rentals are usually done by pros who need a specific piece of gear for a short-term project. Lots of professional equipment is rented this way.

A DAC at $14K (ridiculous, IMO) is rented to someone who wants to hear a particular piece of gear in their personal system who can then decide whether the juice is worth the squeeze. If the purpose is to then buy the DAC or not at new or used price, cost for the experiment $350+ shipping. That business model might work for some things in some places, but I doubt the extremely rarefied market of very high end gear would be one of them. Maybe if you were a dealer of that $14K DAC and you offered the rental service in a large metropolitan area to potential customers to draw interest, you might get a couple of takers, but the clientele would be a small and rarefied group. I doubt there are a lot of fence-sitters thinking of spending that much on a DAC who would be drawn by a short-term rental option, enough to make setting up the business worthwhile, even with the potential for generating a stock of used units that could be sold at a discount.

Camera rentals are in place supported mostly by professionals that need a particular piece of gear for a particular short term assignment. I have used them to try out a lens but found a place close to avoid the shipping barges.

I’ve also used the Cable Co to try out about 10 different cables. But I’m going to say those are less fragile than a Mola Mola.

from the consumer side, I could see spending 750 for a two week in house demo to see if I wanted to purchase. More than that, I can fly to a dealer who can have one set up for me.
 

all in all, just too much risk on your end. 

"Thanks for all the brutal replies. Lots of shade..."

@audio_bidder ,

Sorry no one is coming off all kumbaya for you with posts of positive reinforcement, but these responses are hardly brutal. They’re just apparently not what you wanted to hear. This isn’t unsolicited advice; you asked. Also, no one is throwing shade. No one is ridiculing your idea. If you think its worthwhile, do it. If you don’t, don’t do it. Simple as that. If you still think it’s a good idea, set the wheels in motion. Only way to find out, isn’t there. I'll finish my tough love speech with this; To me, renting out a single dac is like owning a car rental business that has one car.

I think some "creative marketing" with a litthe 4th grade math might be helpful here.

Instead of dollars per day, perhaps provide a little more granularity into the equation.  Cost per complete album, song, or bass riff, rim shot?

"For a mere pennies per  ...."

Local borrowing would be better. Set a minimum number of days, get a deposit, and meet in person with the unit. 

I'm letting a friend borrow my Holo Audio Spring for a couple weeks and he's loaning me his Debussy DCS. No money involved. I could see this moving in the direction proposed by the OP, but not without the local, deposit, and trust-establishing elements.
