  1. PURITY is a relative term. Class A and especially SET add DISTORTION, quite euphonic. The issue of dissasembly and re-assembly is not part of the equation when you get Straight Wire With Gain coupled with Load Independence, (Hypex and Purifi). The SETs are too fussy about load dependence which is IGNORED when talking about Purity by the PURE definition of Straight Wire with gain. It very pleasant distortion with lack of bass. I would never use SETs on a woofer section, but on mid/high, it's heavenly euphonic distortion. The emotional testing part coupled with personal preference is irrelevant, and the high end testers of today (like Ahmir at Audio Science Review) prove me right (he has later/better gear than John Atkinson of Sterophool, BTW). All amps are good past a certain point, yet the industry ignores IM Distortion, which is 1,000 times more than amps in loudspeakers. You need the whole picture in audio, not your own personal slice of the thick pizza or Cake corner piece while ignoring the rest.
  2. Of course. I would rather do class A than Tubes, even thought they are both primarily Space Heaters. Only in the winter, though. I did both for years. There is not argument for preference here, just the facts.
  3. ridiculous power for horns. Bad choice for S/N.
  4. Yep, because the guys that had them cranked them up with too much power. The have High Signal to noise ratio and sound as good as My Hypex on horns. I don't use much power from either one, but the PA-5 was 1/5th the price, so I got 3.
  5. Totally NEUTRAL, no dirt, nor fairy dust, just like the Hypex slogan says. Same with the PA-5 on horns. Dead Quiet too!
  6. I have Windows 11 with a passion. What used to take me 2 clicks now takes me 3 or 4. It's a bloated piece of crap and most other stuff detects it's Win 10 with more garbage on top. Changing the interface is even worse, but they have us by the low ones more than ever.
  7. Like the Country song said: "It's hard to be humble when your perfect in every way." LOL. But we do the best we can, aye? Started going back to Canon Mirrorless from Sony because the DSLr glass works so, I use both since I can fit Canon glass on my Sony's. Trying to Unretire back into Engineering (too hard to earn $$ fromf photography, which is 1/10rh ro 1/3 of what we used to make). The iPhone took the magic out of the craft and there are Trillions of crap images being made too easily. I just taught 3 lighting classes in Chicago for Free and all everyone wanted to do is photograph my 17 models once the LED lights were set up for them (no flash sync. to worry about when teaching). They used their cameras just like an iPhone and didn't want to know anything technical, even though I showed perfect prints of my work from SOOC Jepegs. But that's the new generation we are stuck with. To get back to the OP, welcome to the world of dynamic realism in sound of Klipsch! It's a great disease to have, and you will never find a cure for it. Nor will you try. LOL.
  8. What, no mentions of the beautiful Super Heresy 1's you built and sold off for the Forte IV's? Bow your head now and mumble. LOL.
  9. I'm using the PA-5 as my HT Mains on SH-50's as well as on my EdgarHorns Downstairs. I have a Third as a spare. I'm modifying my Hypexes to have 12 db less gain for horn use with an increase in S/N by 12 db, then sending to Audio Science Review for testing (hopefully) when I'm done. That way I will have data vs. the PA-5. But never A/B's them here, even though I have the gear to do it. My ears say excellent based on the numbers and experience, so now I want the "opinion" of Primo $26,000 test gear I don't own. Measurements and objectivity is a big part of it.
  10. I bought mine without ever hearing and it replaced a First Watt Aleph J clone, which I also used to cook my breakfast on.
  11. I bought 3 of these Tripathi (engineer's name) and still have 2 I use for driver and speaker testing. Had one tested a Klipsch HQ in Indianpolis. The Engineer said I had a "very good 6 watt amplifier." I wish PWK had live to see it. It can run on 8 AA batteries and I used it to sell my Khorns in 2007 with a battery Powered CD player. It sounded great, and I was sold on Chip Amps from then on.
  12. Only in Winter, for obvious reasons.
  13. I had had tubes in my late teen through early 30's, HK Citation, Scott, McInosh 240, and Marantz 8B (approved by PWK himself, as a good amp for my Khorns). I like SET's very much, but you have to have flat crossover impedance to get the best out of them. They are a great match with ALL horns (like my EdgarHorn Titan II's, and preferred by Bruce himself, RIP), especially the SET (also the First Watt class A stuff). Being "Green" conscious and all, I just don't like having Space Heaters in my audio chain and NO fans, which leaves commercial amps (except my Crown K1 and K2's) out of the running. They all work to make music, so pick your best flavor of ice cream. We all have different rooms, wallets, and taste buds. It's a personal choice after all. I have tried them all and made my choices, as you all have.
  14. Most direct radiator speakers (like a Factory Heresy) are 10-20 db LESS sensitive than an all horn system (like my Edgarhorns at 106-112). And I'm being generous here. That being the case, when I had Khorns and built a power meter to keep track of power usage about 45 years ago. It was "stupid loud" when I hit 10 Watt peaks on my Khorns. So the 10-20 db difference in sensitivity translates to Ten to One Hundred times more Peak Power requirement for the worst of direct radiators (the worst being my Carver Amazing Platinum speakers at 84 db/w). So bottom line, the power requirements for smaller, cheaper speakers, (lower than a Heresy) is 100 to 1,000 Watts per channel to avoid Clipping and destroying Tweeters. So quit wasting time bla bla bla about something that should be a know FACT concerning Klipsch speakers and Amazingly good Chip Amps and Discrete Class D (like Hypex, ICE, etc) taking over the world from tubes. I have owned them all and still do in over 50 years doing this in the world of EE's and Audiophiles.
  15. I spent a day in PWK's house. He never recommended more than 20 Watts for a Klipschorn and LaScala. He used a Crown D60 because of its LOW IM Distortion, not for the watts, which were usually 1/4 Watt per channel. Those that say more power sounds better don't know what they are talking about with their opinions from Emotional Testing with NO DATA. You want high Signal to Noise Ratio with horns and the PA-5 exceeds -120 db at 5W. Look up the Audio Science Review. The only people that had reliability issues with the amps pushed them too hard in inefficient speakers. I have 3 of them on my All Horn Systems and they are incredible. Best Bang for Buck
  16. I'll give you my thoughts, since you asked. The TI 3255 Chip is an amazing device. Just how well it's implemented in lower wattage than the "max" rating makes the difference. Everyone is barking up the wrong tree about this. You "ahem" review reminds me of the You Tube video from a fauxtographer and his cute wife testing out all the 85mm lenses on the market, photographing a mannequin head. They then declared a Nikon 105 MM to be the winner. What an insult and a waste of time. If you are all about all horns and big horns, like I am, you already know that big watts don't mean a thing to a Klipsch guy or gal. Also, this is an old PA-5 thread, so why are you judging negatively an amp that your go "cheap" and not a PA-5? Emotional testing without data, is just another opinion, especially with all the flowery word BS that comes from StereoPhool and Absulutely Soundless magazines whose reviewers listen to good MUSIC in crappy room. Waste of time.
  17. I'm assuming your are still enjoying LaScalas with flat bass to 30 Hz. or lower with the affordable "upgrade?" Just in case Tony and Lady have a band whose bass goes that low!
  18. Ah yes, Kelly Harmon, daughter of football star, Tom Harmon, sister of Mark Harmon on CSI, married John Z. DeLorean which made the other GM wives jealous. Gorgeous woman. All the siblings were movie star gorgeous kids. Anyhow, I photographed JJ without the morning crew and all the WRIF, WMGC, and WCSX Jocks, including Arthur Penhallow, right before he quit the RIFF, because they didn't want to pay him what he asked. But that's another story. I guaranty you that none of those 3 stations ever played even ONE Tony Bennett song! (Hey, since I'm the OP, I gotta keep it relevant!)
  19. I had a Detroit News paper route in 1968. Like any 13 year old, I loved music and listened to CKLW in Jr. High, which was a 1.5 mile walk each day. I saved money and bought a Zenith portable AM radio and a pair of Koss Brown headphose (they probably had 3" speakers in them). The radio came with a mono ear bud on a wire, so I cut the ear plug end off and wired the 1/8" mono plug to a 1/4" female adapter for the 1/4" headphone plug (wired in Mono, using the bought all this at Lafayette Electronics. Cassettes were just coming along then as a music medium. My dad told me I looked ridiculous with those things on my ears, but they kept them warm in the winter too. I may have invented the first walkman, and my friends think Sony stole my idea. LOL.
  20. I attended the same Elementary School as Stevie Wonder when I moved to Detroit from Quebec, Canada. He was 4 years ahead of me, but he was a legend among teachers in his early teens!
  21. I bought 3 of them. One spare and the other two in full time use on Edgarhorn Titan II's and in my full Atmos HT/2.2 stereo (at the couch of a button) upstairs with the Danley SH-50's. Yamaha YPAO room EQ on both. Best bang for buck amp EVER. The guys that had trouble with them use too much power on INEFFICIENT, non-Klipsch speaker. But we know better!
  22. Singer of the Great American Songbook for decades. I especially like the collaboration of his voice with various young chicks! The man was THE MAN!
  23. The effective mouth size of a Klipsch Bass Horn is the walls of a room corner, which is 4x4 feet. Since the Undergroound Jublilee and the Klipchorn bass horns were designed for a corner, they become 8 foot long horns. The mouth of a LaScala is too far from the walls to be as effective as the Khorn or the Jubilee in BASS EXtension department. All speakers have Cabin Gain in small rooms (those in most homes) and this is why Klipsch can make shorter horns that take advantage of this.
  24. You can buy good subs in kit or assembled form, much cheaper at Parts Express.
