I'm just an end user sharing my personal opinion based on my real world experience. Not buying or selling , therefore the only person I need to to prove anything to is ME. Definitely do your own due diligence like I did mine. I also agree w,Jriggy find the speakers you like then worry about cables, tweaking, etc after.
I personally could not waste the time/investment of flying to RMAF (as much as I would like too) to check out Lou's speaks. IMO rather put the $ into the gear/music.
As you can tell already, Lou is a great guy and he hooked me up with a Da-rma (w/o AP mod) owner near my house and I spent several hours listening and grinnning from ear to ear.
So now that your investing your time/money to check out his speaks,etc and perhaps be able to do a cable swap, you can then substantiate my rhetoric
That has to be the way of Demoing any item sold direct in HiFi, particularly heavy items like speakers. You look at the other small manufacturers, Tyler, Reimer, when he was still around. They kept lists of customers happy to Dem for them and connected them up with potential purchasers.
I would actually prefer to go to a home Demo, not a shop. With the latter, you are acutely aware it is their business. You can detect the desparation in some of them, the need to make that sale. I never go to a shop unless I am ready to buy from them, if I like the product. It is quite wrong, in my opinion, to buy elswhere or second hand. Still, you feel under that subliminal pressure.
At a home demo, there is no pressure. You can often take some of your own kit and spend a pleasant few hours, with a fellow enthusiast/obsessive.
Just to remind anyone interested, my AP modded Da-RMas are available to hear in the Southern UK, near Oxford, if anyone is interested. Lou will put you in contact
