No if its not the exact amp it will sound different 

No $300 to audition .if you like it the $300 is deducted

You should get 15% off 

If you’re happy with your system, then your reply should have been no thank you, I’m happy with my system. And unless the $300 would go towards a purchase, that is an obscene amount of money. Either way, the guy was way to pushy for my tastes.

The fee to bring the amplifiers over to audition might be worth it if you can leave them in your system for a few days to get a sense of how they will sound in your system. The fact they will deduct it if you buy is fair in my opinion but I am a Pass owner, an Aleph 5, 60 watt per channel class A that sings devine with my Watt/Puppies.

   Personally I would give it a shot, the only downside is you might want them and it is a big purchase but I have a feeling you will enjoy them quite a bit.

In any case, don't forget that the amp should be fully burnt-in before any serious audition. I don't know about Pass amps but probably hundreds of hours. And power cords matter too, along with all the cables. This would be quite a purchase, so everything must be as it should.

Wait until they or someone else can offer you the exact amp he’s recommended. It will sound different than the one’s he’s actually recommended. Find other opportunities to listen to the amp he’s suggested in home or in store or at another customer location.
