Ok, then give us an update on the installation and initial sound quality results of the Incito S. You have your masses to entertain! ;)
 
Congratulations, Ron!

I’ve spent time with the Incito S, Ageto, and Aether Pre-Amps, and also listened extensively to the Impera. The Incito S is truly something special, especially at this price point.
I’m eagerly awaiting my own Incito S and Aether Pre-Amp (Legend Series)!

Hi Brad,

Sure! The update is that there is no update. I haven't moved the unit from the crate in its original location in the garage.
 
Yes, but physics does not tell you that a fuse can't affect the sound quality of high-end equipment.
Not the fuse, but Voltage drop across the fuseholder. You can measure it just like you can Voltage drop across a power cord.

Some equipment does not care (for example our MP-1 preamp, whose power supplies are heavily regulated) and some equipment, especially that which has a heavier power draw and no feedback, like our MA-1 amplifier, does.

SETs will be prone to 'sound differences' of fuses and power cords since they have no feedback. Our class D amplifier, which employs about 37dB of feedback and has low power draw at idle, is pretty well immune to fuse and power cord changes. Feedback in high enough quantity (and properly applied) allows the circuit to reject that which is not the signal.

I recommend to our customers to avoid boutique fuses as they are expensive, don't always blow at their rating (may be higher or lower) and because the Voltage drop across the fuseholder is really what you are hearing. In most fuseholders the fit is not perfect. So sometimes you get lower Voltage drop by reversing the fuse, which has led to the myth that fuses are directional. You can get the same effect by simply spinning the fuse slightly to obtain a better contact in the fuseholder. A measurement of the Voltage drop will confirm the correct positioning of the fuse in the holder.
I think a lot of tube life also comes down to how hard do you run them...My Mercury rectifier gets run hot. As such, I seem to fry them about every 1000 hours.
FWIW a mercury rectifier has poor application in a modern tube amplifier. You're better off with HEXFRED devices, which are super fast and super soft recovery and can handle currents far higher than most tube amps might draw and can be made to be lower noise quite easily.

Mercury vapor tubes are used to reduce the Voltage drop across the rectifier and are also high current, usually much higher than you see in conventional rectifiers like the 5AR4. For this reason they were used as rectifiers for charging batteries and the like. They are also very reliable (and so can last decades) since the mercury cathode is self renewing. If yours are failing the application is really not right or may indicate that some other component is drawing far to much current. I'd get that sorted out if I were you!!

We’re talking about all electronics, not just SETs when it comes to fuses…

Thank you very much! I am excited to try it when I get around to it!
 
Ralph, Brad!

Please cease on my system thread the irrelevant discussion of fuses.

Due to some technical glitch did this post appear on your computers in Portuguese instead of English, and so that's why you didn't understand it?

Is it irrelevant? The fuses themselves are; the reason people hear differences they think are associated with them are not. I addressed those rather than the fuses.

I put up my post because IIRC your power amplifier is a fairly high power SET, using dual output transformers in each channel which are then paralleled at the output. This helps avoid bandwidth problems usually associated with higher power SET circuits. I figure its efficiency at about 20%, which is to say it draws a fair bit of power. It is also zero feedback and class A which increases its susceptibility to power cords and the like. If you look at my last post, you'll see I stated exactly that; it is relevant if you want to get the most out of your amplifier dollar investment.
 
Here’s something on the topic of Ron’s new system. The tags or links need editing. They refer to gear that I think Ron is no longer using. Perhaps we need a refresh to the thread to get us discussing the new system with the current lineup of components.

Ron was very accommodating, even charitable, with those old videos he made and shared. I kind of miss those.

I ve gotten plenty of useful information about components from his very thorough reviews [of Christiaan Punter, HiFi-Advice]
[please forgive my poor English]

Waiting for Ron to share his first impressions with us, regarding Christiaan Punter, I'd just like to add the following. I don't know him personally, but as far as I can read:
- thorough reviews indeed, I agree;
- he is a broadcast professional who uses DSP-corrected active Genelec monitors (in another room). But obviously he seems to enjoy very much subjective reviewing too;
- he clearly stated that he had left the standard fuse inside the Incito S anyway.

Can I just add that I read your posts regularly and you genuinely have no need to put a disclaimer on your English, your posts are always erudite and easy to read… that it is a second language for you doesn’t show up at all in your writing.
 
I'll bet you wonder about mine lol
Al I wonder about myself also at times… we can all go a little abstract just to mix it up when trying to relate our experiences and individual perspectives in the predictably sequenced ducking and weaving parrying and thrusting (then rinse and repeat) of forum life. Especially in the increasingly more Groundhog Day audio thread categories.
