    SETs and Horns

    Hello! I really have no idea. To my thoughts, all this is related to marketing policies and attempts to downgrade the amplifier portion for good sound requirements and focus on loudspeakers by emphasizing electronics built in house. AG speakers are hybrids, semi-passive and semi-active, you...

    SETs and Horns

    There exist no more reliable devices than tubes. They are more reliable than transistors. Just operate them with circuitry that is properly designed and adapted to their specs and and you'll never face any issue. I have been stressing power tubes to their absolute limits and I can hardly notice...

    SETs and Horns

    The Altec horns don't go lower than 500Hz. More specifically, they *should* not go lower. The horns themselves may reach 300 @-3dB but the drivers are not manufactured with the aim to go there. The only driver (besides specific Ale & Goto drivers) that goes down deep to 100 Hz and plays full...

    SETs and Horns

    Yes. GIPs are the best replicas by far. No comparison to other stuff. When it comes to comparing against the real thing, well, they lose. The WE guy is not a friend, he is the NO. 1 WE guy in the world. He owns everything, he knows everything, he has listened to everything, he has built...

    SETs and Horns

    Yes, I think that Wolf Von Langa has manufactured field coil under hung woofers. I have not listened to them. And of course the manufacturer of the best field coil woofer I have experienced, under a commercial scheme. The flagship model of Shindo, think it was named Latour. Modern variants...

    SETs and Horns

    Yes, it is so easily explainable. In the past, in the era where the amplifiers were pushing low or moderate power output, high efficiency loudspeakers were necessary. When power amps of 100, 200 or 500 Watts of output capability appeared, the necessity for high efficiency vanished. So almost...

    SETs and Horns

    One more guy that confirms what I've been telling for more than 10 years. At least, it seems that there are quite a few here in this forum that prefer to write the truth, instead of hiding around, having the preoccupied idea that they will be accused of blaming manufacturers, challenging egos...

    SETs and Horns

    Although your comment seen as a whole, is one of the best I have read, I have some things to mention. The artistic part of a performance has nothing to do with the 'rightness' of the reproduction of this performance. Hope you get what I mean. Vintage violins for example have gained a unique...

    SETs and Horns

    I have some experience with Thomas amplifiers, though not with the specific one equipped with these 46 tubes. These amps are among the best machines or there for sure. Don't consider my words as a praise for Thomas amps, I never do so. If they were bad sounding, I would openly comment against...

    SETs and Horns

    If I am to choose a low power tube for an audio amplifier, among the classic tube variants, I would definitely go for 45. I am not experienced at all with 46, so I can't comment on this. As soon as Bill declares his preference, I cannot comment on this,logically it has many pros. I had played...

    Zero Distortion: Leif's System with TAD 4003 based dual FLH

    Hello! To my knowledge, Mirrophonic was built with 2x TA-4181As. This is justified by numerous pictures around...

    SETs and Horns

    Hello! Would just like to add my two cents on the topic. Having manufactured already many SET designs, like phono preamplifiers, line preamplifiers, MC step up transformers and of course power amplifiers, all with custom manufactured iron in double c core fashion, with custom ferromagnetic...

    Zero Distortion: Leif's System with TAD 4003 based dual FLH

    Regarding FLH, it is a very good solution to have really good low to high mid range performance. But for best performance you do not need FLH for woofers. Just stick to the classic solution, 2x 18" field coil woofers, paired with WE555 mounted on WE13a FL horns and couple with WE597a tweeters...

    Zero Distortion: Leif's System with TAD 4003 based dual FLH

    Hello from Athens. I have several weeks, perhaps months to visit the forum. I would like to put a couple of comments here, related to my experience. You have posed nice questions. 1. Open baffle speakers are *completely* different than cabinet-enclosure speakers. The speakers that are proposed...

    Network Improvements and their Impact on Sound Quality

    If I didn't have any switches at all and if I was living in usa, I would go and buy them all at once. I would use them in stacked quads and would never look back again, regarding network upgrades. It is by far the minimum expense with the maximum reward related to SQ uplift.
