To DAC or not to DAC?

IF the dealer is a long time relationship to you, and you have bought stuff there for years....
Ask the dealer for a LOAN of what he recommends. If he cannot allow you a free loan to try at home... for say five days? Then he is just selling stuff.
Mu long time dealer, who suggested to me, out of the blue, That I take home a Marantx SA-10 SACD player to try.. OK I did. I decided to buy one.
SO if the dealer thinks it’s like THE THING you need. Why is he not handing it to you asking you to try it out? Does he not know you? is he new to being a Dealer? If like he does not have one in store that he uses to demo....
Ask if he will let you buy it (if he can’t for some reason loan it to you) And guarantee a 100% refund (NOT store credit) if you do not like it?
If he is so sure you will love it, then he will take the chance. If he is ’just selling you something’ ... then he will not.

Instead of ’cuttin’ the op for his private comment in the thread about his purchasing habits, which IMO are his own business, not mine! For those who think they are the "Audio Morals Police Force." I suggest you take it offline.)                         
I will go back to the other question raised in the responses..Which is: is there a difference in DACs, and why such a big price spread? I have to say all audio components have a ’big price spread’. So do cars, homes, vacations, watches.. You name it the item can cost litle or a lot. DAC are no different.
As for sound... I have a DAC I paid $250 for, used. had it around fifteen yeasr? anyway, I finally found something I thought was enough better to buy. $250 vs $7,000 to gain a small improvement in sound. It was no earthshaking oh my gawd change. Just sounded better ENOUGH.

So... you are saying braising my DAC will improve the sound quality way more than burying it? Any special sauce??? Is this with Hickory? or can I use any fuel?

"Audio Dealers" should be a whole 'nother thread.

Car dealer salesmen... I have to say it is sad about how ill informed they are about the cars they are selling. I would think they might spend time keeping track of inventory? nooo, what features on models? nooooo, what current rebates? noooooo My last purchase I asked at my favorite (of 10 Ford metro area dealers) Focus ST.. after They seemed to be confused I wanted to actually buy a car.. no responsive reply ...I left. They had no interest in even selling me a car. Went to second most favorite dealer, guy greeting, supposed to be a salesman, Jeesh dumb as a stump. I left called asked for General Manager, and raised H. He connected me to a ’rising star’ (salesman family member of owners!) and with zero hassle I ordered the car I wanted, $3000 off list Zero interest financing., plus I got a good price on my trade in. (It was funny.. they wanted to give me less for my tradein since it was a stick shift. I said then give me another couple thou off the new car since it too is a stick. They caved.
