fuses - the $39 ones or the 85 cent ones

Tbg, do you mean down to 200hz or up to 200hz? Controlling bass is the toughest, no? Darn, I guess this should be a new thread, I have some DIY room treatment, but truth is I don't know what I'm doing when it comes to room acoustics (other than I think I have first reflection points covered), but I just can't believe fuses can be anywhere near the order of magnitude (quantitatively and qualitatively) of the changes brought by proper room acoustic treatment which I would think is almost as important(some might argue more so) as the impact of changes in amps/preamps, speakers etc.

Pubul57, yes down to 200Hz.

I do think a bad room is hard to get right and expensive to even attempt it. I think fuses can make a very nice improvement at a reasonable price. Painting the fuse with AVM can also add a lot.

Treating the room should be on the short list.
And, Bass traps aren't that difficult....Corner traps and cylinders are fairly easy.

I just suggest that the right order of operations is room first, than 'icing', if you can even demonstrate differences in fuses!

I don't mean to be harsh, but saying it don't make it so.
Every double blind drug study features a small %age of people getting well on sugar pills or sugar water.

Any room treatment I have done has been obvious and easily heard. Even the spouse, who couldn't care less, makes note of the big changes. She wouldn't say it if she didnt' notice, either. She is pretty honest about these things.

Have fun with hundreds of $'s in fuses, but I think the money could be better spent on the room, 1st.

Magfan, certainly your saying that fuses don't matter don't make it so. Don't mention double blind tests as they are invalid tests for audio. Stop mischaracterizing what I am saying. I have never said that having a good room is not a top priority. I have said that your characterization of room treatment being inexpensive is utter nonsense in my experience as "cheap" treatments don't treat lower frequencies and in my experience at least take the life out of the music. Bass traps are hardly high in WAF and tube traps are one of the worst things I have ever tried.

I am happy for you that you are satisfied with what you have done with room treatment, so am I after all these failed efforts. I would not be discriminating between Hi-Fi Tuning and IsoClean fuses if I did not hear a difference. You seem to want to argue about some efforts being easy to hear and others not. Have you compared fuses and had a hard time hearing any difference? If you have, fine don't buy better fuses. Your experience, however, may not be that of others. If you have heard the fuses than shut up.
