Hifitime, that's good news that you are not a solitary audiophile.
I belong to a little audio group which gets together every week on a rotational basis to listen to socialize and listen to new tunes and the occassional piece of new gear.
Saddly ,as we get older(we've been doing this for 15 years plus, and used to belong to the WNYAS)our purchases seem to be less frequent.
I know the benefits of group participation, and getting feedback from others when you contemplating a move in a new direction.
Also, if other's ears are hearing what you are hearing, it's a good bet you aren't imagining things.
This is so much better than being an audio hermit.
You can benefit and grow from experiencing different systems in different homes.
It also doesn't hurt if one or more members have deep pockets.
The most beneficial lesson I learned was how important the delivery of electricity is to the sound of our gear, and how it can affect the sound, from the panel to the fuse and everywhere in between.
I would suggest that you take a poll in your group about what is the most common fuse you may share.
Then chip in, buy the fuse and send it around to audition in whatever component it is matched for.
I think this would be a fun thing for a group of audiophiles to do, and you may be surprised with the outcome.
It may make an improvement in all or some of the gear, but at least it will be some added infotainment, and hopefully you'll post what you find out.
We are supposed to be an audio community,we don't always agree on everything and we all don't own the same systems,but what we do share is our passion for the hobby.
If your passion is to obtain the best sound you can, as it appears,then try out the fuse test with your friends.
