Systems are made up of components. Many times one component will"make" a system. I agree the relationship between the amp and speaker is critical. You have to find an amp the speaker likes. Another critical, maybe the most critical, is the preamp,many times I have heard a preamp completely change the character of a system. We all agree on system synergy, but sometimes that one component can ruin synergy or make it.
People like myself buy and sell gear for several reasons. Some are searching for a sound, some like to try gear, some just like buying gear.
whether they succeed at whatever they are trying is not really important to outside observers but to the person doing the buying and selling.
Can you imagine you find a pair of amps you like, and settle with them for life? Perhaps it is possible, most normal people do, but we are audiophiles, our stock in trade is the trading and swapping of gear, that is what we do, and that is why there is a large used market out there and why Audiogon does so well.
So Charles, you put those class d Arions in your system and you love them, would you not try anything else? If not just for curiosity's sake?
Of course you would...we all would.
Some people have the ability to buy and sell gear more often than others, perhaps they have more disposable income, others may have access to lots of gear to try, and they do. Some of us have lots of friends with gear that enjoy letting us borrow it for a while. God know we audiophiles tend to be a very generous lot, and we all seem to have an extra preamp or amp lying around...no?
The idea of trying gear seem to me what being an audiophile is about. Music loving is a whole different topic that has nothing with being an audiophile. You can have the shittyest system in the world and be a music lover. God knows Beethoven was deaf in the end.
So trying gear is a good thing for audiophiles
