Which DAC makers let you do in home trial?


I'm interested in comparing some DACS for purchase, maximum price about $1600, let's say.
Auditioning them is a hope.
I know that people can get speakers and sometimes amps on trials from manufacturers and from some brick and mortar shops.
So, my question to you all is:
Have you been able to audition DAC's in your home? Which companies with good at home trials and return policies (besides Ps Audio, which is great about that but their DAC is super expensive).
The alternative is just to take a shot in the dark, which I'd prefer not to do. I like to take time and assess before spending this kind of money.

The Digital Amplifier  Company DAC doesn't have a tube option. It's called Tube Like, the DAC TL. It distorts similar to tubes. 

How can this thing sound so wonderful, but measure so-so?". Well, after taking a better look, we discovered that the distortion characteristics of our shortest-path circuit were similar to that of tube (a.k.a. valve)

Hide45, does the Node have input connections (optical or coax) for your CXC? If so you are set for a source to use while evaluating amplification. 
It does mesch and I have an Audioengine D1 DAC too. So those should hold me through speaker trial and amp trials, I'm assuming.
