Prima Luna Dialog 3 vs Dialog Premium

NOT an owner of a PL pre, but have been enjoying PL gear(Dialogue HP Intgd)

Unless you MUST have the current model, D3 used, and splurge on nice glass.
A better bang for your buck for 1/2 (or less)the retail.A used Prologue Premium will save a couple more bucks.
Dialogue level PL gear just makes whatever source sound good for a reasonable cost.
Blame setup,room,speakers,source,cable,etc for whatever you feel is deficient.

I've heard PL setups with some of the best everything. I don't hear another $500K better in the mega systems. 

Kevin, the distributor is the source for facts on PL.

The Dialogue Premium pre-amp is a step up from the Dialogue P3 in terms of performance and flexibility / utilization.
Here's a link that depicts internal components/circuits used in the Premium. http://www.primaluna-usa.com/dialogue-premium-preamplifier. So It's dependent on you and if you want the best or  would rather settle for the lesser to save money.
I personally would select the better of the two. Even though more costly then the Dialogue P3, the Dialogue Premium is still a high value component, and I think with enough looking and time you can probably find one used, if you want to save some cash.
I saw where there's a listing for the Dialogue Premium Amp in usaudiomart.  An option would be to run an "Wanted Ad" for the Pre-amp in usaudiomart (free)

   

If you go to the Primaluna web site, you can download Owner/Operator Manuals for both the Dialogue Three and the Dialogue Premium. Both have a description of parts used and specifications that you can compare.

fair price, and if you don't like it, you should be able to get your money back reselling it. If I was looking I would grab this.

It would probably be interesting knowing what you decide on to purchase
