Fred Volz told me, maybe 10 years ago, the best sounding preamp he ever made had the Epifania circuitry with Slagle autoformers on the output. @Glide3 maybe that was yours? My custom Epifania predates that one.
I also have a standalone Slagle AVC box and I have compared it to the Epifania...
“Modern” and “Vintage” are somewhat in the eye of the beholder. In my book, 1994 is modern! For some context, my woofers were made in 1947. They are 15” Jensens with paper cones and Alnico 3 magnets. My previous Jensens were 10-15 years younger and sported “modern” Alnico 5 magnets. The...

I have been through a similar process of going back and forth between active linestage and passive. In my case, it was between an Emotive Epifania tube linestage and Slagle EMIA AVC passive. For a long time, I preferred the very slightly better clarity and bass weight of the AVC...
Here are two other important design elements that are easy to spot from just a peek inside the chassis. First, no toroid transformers. Second, if the tube heater supply is DC, as most are, there should be a separate power transformer for the heater supply. Feeding the heater rectifiers from...
My feelings exactly. I don’t discuss my electronics very often in this forum since they are all DIY but you just described my phono stage—-two tube stages per channel (D3a and 5687) with nickel output transformer, no loop feedback, outboard power supply with tube rectifier, all parts selected...
Your description of “hard, brittle and bright” just sounds so different from my experience. I would describe the GL KT-77, once fully broken in, as a warm tonal balance with a rich lower midrange and slightly soft treble, with excellent dynamics and excellent midrange detail. Of course your...
The gold lion KT-77 change rather dramatically after a long break in, more so than any other output tubes I’ve tried. If you didn’t use yours for at least 50 hours, I suggest you try them again.
I am skeptical. I just checked Michael Percy’s Audio catalog and he sells the Vishay TX2352 bulk foil resistors (their top model) for $11.95 each for most values. Now it’s true that values over 100K do cost more, up to $39.50 for 249K, but you can still buy the vast majority of values for...
I agree. Since I use woofers made in 1947 and a midrange horn made in the late 1940s, I could say that anything made after the Korean War is modern. But I won't.
Words like "right" and "wrong" overstate the issue. Like everything else in a system, cables should be selected to give the proper balance, and sometimes a particular silver cable gives the best balance, and sometimes a particular copper cable does. I said "particular" cable because not all...
My complaints about modern speakers are that most of them:
(1) have unnatural bass. With many the bass is too lean in the upper bass and lower midrange, not warm enough, which contributes to a sense of restrained dynamics;. With other modern speakers, the bass has an unnatural boom and thumpy...
There’s an interesting review of the EMIA Remote Autoformer in the April 2024 Stereophile. The reviewer Alex Halberstadt actually had two versions at hand, the copper and silver, and overall he seems to prefer the copper. I have the copper Slagleformer in my system but I haven’t compared it to...

We each have our own comfort level. All of the big crossover caps in my speakers are old paper in oil caps from the PCB era. None of them are leaking and I use them all standing up vertically to minimize any possibility of leakage. I would like to use non-PCB caps if they sounded as good but...
