https://www.amazon.com/gp/product/B07SHLS639/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I just bought this one because I got tired replacing the 9V batteries, so far it is very accurate, specially when test capacitors.

Ferrum support was smoking something, it is their fault to choose such odd ball socket. It is NOT the fuse sound REALLY bad then backward, they sound little artificial, awkward (unnatural), and MAY gain some dynamic and have wider soundstage when backward, yeah it is funny.

How ever this is correct:

Like this:

The direction in the pic/drawing above is backward

If your system has 6 or more fuses, it is very hard to single out each one before you get really mad, sad, or just want to kick something!! I been there, just before I tired to kill myself, I took one step back look at the "industry standard" that is if you look at the fuse facing the logo...

If the system is detailed enough, people will tell the difference, but the process is slow, the ears might adjust to the sound already that make it hard to tell. I had my preamp ordered new and listened it for a few days, then I hooked it up with a CDP, took the bottom cover off, placed a fan...

You have to play music or noise to let some current flow through the fuse to burn in, all the fuses I have their sound improve pretty linear.

If the fuse is installed in a wrong direction, the sound will be odd. If the fuse's direction is not marked like Hi Fi Tuning, the general rule is look at/face the name and lettering, the direction is from left to right.

Rattling is OK as long as they sound good, also there is nothing you can do about rattling.

Used Synergistic SR20 when they first came out maybe 10 years ago, anyway, it was a long time ago, the fuse changed the image shape and sound stage too much, the music flow was not natural.

It depends on your system, I am still using the old AMR gold fuse, Created Audio, and Gold Hi Fi Tuning, never seen the needs to replace them, I am really careful not put N th degree of details, wide sound stage, sharp/clear leading edges, and…… the list is long into my system, I have enough...

Sorry I can’t remember that was a loooooooong time ago but I can tell you that use 6SN7 instead 12AU7 family tube is a generally a good direction. Change the coupling caps or bypass them with something like jupiter copper foil caps is a cheaper and more effective way to improve your WA22 instead...

Well, GL used to be $200 a pair, now WE300B replicas by PSVane and LindaI are both over $1000 USD and for $500 more you got US made Rossville WE 300B replica beaters......hum.....all don't make too much sense anymore.

They look like are toning caps

Has anyone tried new Jupiter VQ and Comet caps? https://jupitercondenser.com/collections/audio-capacitors They are so new that I can't find any info on them, how they sound and tonal signature.

All the reviews raved about MZ3 are true, great sounding amp BUT it had (was in my system) the opposite tonal balanced to Cayin HA-300, just be careful! MZ3 was very transparent and "crisp". When comes down to MZ3 and Cayin 300B, it is all about personal taste, just discard all the BS reviews...

Crazy money show......

And don't forget great OTL amps as well. Single ended all the way, balanced design is relatively unnecessary, because in a lots of cases, it adds technical correctness to the sound signature and takes away emotion and timbre.

After many years of burning Benjamin and gear changes, looking back at my old path with WA22, it was wild and crazy to try everything first-hand, experiences gained and benefit my entire Hi-Fi life, the WA22 was rather a learning tool to me than an instrument to enjoy music. There was a lots...

I am hanging on my CDM V1, love that thing, LOL

Thanks, I had his cable before for my HD-800, the workmanship was outstanding.

Are they still in business? They used to have a large selection of adapters, now they are not on their website anymore, and their product line seems limited to a few models.

Not to mention MC60s are bass monsters for tube amps. I had MC60 mono, now rocking a pair of MC30 with Yamazaki mods.
