Because of COVID-19, some of these store may require an appointment. I do not know. Please see the web site for these stores to see what DAC’s they carry. Have fun.

@ericsch, Unfortunately, The Analog Room store in Campbell, CA is closed.  I agree it was a great store and I liked working with Brian.  

His web-site says "After over the last twenty-seven years of being at the forefront of analog two channel Hi-Fi sound in the Bay Area, we are retiring"!    

Another audio store to visit and they definitely require an appointment.. They carry some interesting brands:

Elite Audio San Francisco

If you are looking for a DAC, please look at the Bricasti M3 DAC (they also make other DAC models)
