You say you want "better" but what exactly would "better" sound like? Would you recognize it if you heard it? Do your research, read reviews, compare specs and listening impressions but in the end, you are going to have listen for yourself.
If you are not in a hurry and enjoy buying and selling, you can always buy used and sell it if you don’t like it. Whether you do this, or order from one of the online vendors who offer return policies, it still amounts to the same thing -- basing your ultimate decision upon what you hear, in your system, in your room.
Even if you had a half dozen dealers close to you it’s unlikely any would be amenable to a home demo. That is simply not their business model. Among others, The Music Room, Audio Advisor, Listen Up! and Upscale Audio all offer return policies on online sales.
The alternative is to buy new gear based on someone else's opinion and hope you like it. This might work out. But then again, it might not.
