Fuses that matter.

Hifisoundguy, if you think so. I imagine they make your Bose speakers sound good for you.

-----------THE RESULTS ARE IN--------

Today I had an opportunity to A/B the Hifi Tuning fuses with the stock fuses. As I was alone, I was not able to A/B/X. For those of you who believe that that invalidates my observations, you can stop reading. For everybody else...

The answer is Yes, I heard a difference between the Hifi Tuning fuses and the stock fuses. Here's the good part...

I preferred the stock fuses.

I suppose that makes me a fool twice over. First, for buying the damn things. Second, for initially preferring them. In my defense, I didn't hear much of a difference when I put the Hifi Tuning fuse in my *preamp* a few weeks ago, and so I didn't actually prefer it to the stock fuse. When I put the Hifi Tuning fuse into my *amp* a few weeks ago, there was a noticeable jump in headroom. But I could NOT reproduce that effect today. I therefore suspect that the initial jump in headroom was attributable to...

1. My imagination.
2. The possibility that the new fuse was clean and the old fuse was dirty.
3. The dog turning up the volume while my back was turned.

Returning to today's results...

What I DID hear today was a "phasiness" with the Hifi Tuning fuses, which sounded like a combination of decreased clarity, softening of transients, and slight loss of imaging focus. This was most perceptible in the bass during fairly loud playback.

For those of you who think this is all nonsense, I don't really have a good response, since I did not A/B/X. So I am prepared to endure your ridicule.

Hi Bryon,

As you might expect, I'm not surprised.

Among the three possible reasons that you hypothesized for the non-repeatable initial perception, btw, I suspect that reason 1 was not the cause, and it was due either to differences in contact integrity or to actions by the dog. :-)

In view of your findings, and the comment by Wrm57 on 5-1-12 as well as my technically-based comment on 4-29-12, it would be interesting if some of those who swear by the expensive fuses were to undertake a comparison between a number of different kinds of inexpensive fuses, performing the comparison in a manner such that the possibility of extraneous variables affecting the results is eliminated, per my post of 4-28-12.

Best,

Bryoncunningham...maybe you put 'em in backwards.

Hifitime , my Bose 901's has never sounded better after putting two coats of Elmer's Carpenter's Wood Glue on the paper cones and dust covers !!....

The purpose in doing this is to tame breakup resonance modes. In doing these coatings on these paper cones, you are able to extend the frequency range on both ends and avoid ugly response peaks in the midrange of these paper cones.

In all the years that Bose has been selling these 901's I'm amazed that they have not tried using treated paper cones !!...
