  1. Be cautious, I tried to buy a pair of Heresys in San Francisco but the seller would not give me an email address or phone number to contact him directly. He gave me an address -- I think it was on Pine Street, but no way to arrange a time for pick up.
  2. Aren't the connections through RCA coaxial connectors? Why bother going through the wall for a week? Connecting speaker wires to RCA receptacles, especially if the wire gauge is large--like 16 or 14 or 12. Let us know how this works out.
  3. I don't get any noticeable hum with Khorns and an 8600S Elekit 300B amp. LED lights can be a problem. If you have them, turn all of them off just to check. I'm puzzled how "sonic signature" would be enhanced by keeping some hum. Actually not sure what sonic signature is.
  4. Relevant discussion at https://www.audiosciencereview.com/forum/index.php?threads/record-breaker-raphaelite-cs30-mkii-tube-amplifier-review-and-measurements.44020/ discussions of the 300b Venus tube. Comment the Western Electric product has low distortion. I think probably because of high cathode efficiency analogue to Klipsch speakers.
  5. rather than tapping amp output, consider tapping the crossover's bass output.
  6. If you can solder and assemble, also take a look at Elekit amps 8600S and 8900. both are 300B. Reviews in Stereophile--search for Elekit.
  7. Not Heritage, but I don't recognize the model link. https://santabarbara.craigslist.org/ele/d/santa-barbara-klipsch-speakers/7698553699.html
  8. Gentle suggestion to use an ohm meter (voltmeter set to ohms) to check the speaker resistance while disconnected from the amp.
  9. So are these the speakers that just needed breaking in, or are there two LaScala posts and I'm confused. Nice to see a favorable mention of Crites.
  10. I don't remember being disappointed in my Khorns when I first turned them on. Something must be wrong with these pair. Let's see the data for any change in the speaker output during "break-in". Your personal experience won't convince me--maybe it's just getting used to them, and there is no change. Change my mind with measurements.
  11. try a different amplifier, maybe even a tv sound out source. You have to find out if it's the amp or the speaker. Do both speakers do it? have you switched the speaker wires to see if the crackle stays on one speaker or moves to the other?
  12. Update here: I am enjoying the Elekit 8600S 300B tube kit. After making sure it was operating correctly, I bought a pair of new WE 300B tubes, but didn't need a matched pair (the Elekit has auto bias with--sound the organ--transistor circuitry) or a wooden box, so that saved a few dimes. The sound is wonderful through my 72 Khorns with Type A crossovers. Way more than enough power with 9W output. I'm using Telefunken 12AX7 and 12AU7 tubes in the front end. There is only one input on the amp so I have two four-position audio switches to select between my Vincent Pho 701 phono preamp, CD, iPot aka iPod, TV, and FM tuner. See my post under Two-channel about Elekit reviews and 12AX7 tubes culled from Stereophile. Peace be the journey
  13. It's nice to listen to the gear yourself, but that's especially a problem in the case of kits that need to be built first. And I'm sure I'm less qualified as a listener than many who do it for a living. At Stereophile they mostly listen to stuff that costs many tens of thousands of dollars -- more than my budget. I only have Khorns because I bought them when they were under $1K. EleKit Tu-8600RS: $2080 as reviewed ($1695 basic version) As the name suggests, the EleKit TU-8600R is a build-it-yourself power amp, a single-ended design that uses one 300B directly heated output tube per side for a specified output of 9.2Wpc at 10% THD. (A pre-assembled version is available at extra cost.) Prices start at $1185 without tubes and top out at a $2985 version that includes Lundahl output transformers and deluxe German-made Elrog 300B tubes. Herb Reichert tried a variety of 300Bs in his Lundahl-equipped review sample and praised the EleKit for sounding not warm and soft but "fast and vigorous, as transparent as any amplifier, and extremely captivating," with a sonic character that's "clean, neutral, and precise." HR's conclusion: "This is what I call value for money." Other kits are available, but availability is sporadic. In his May and August 2021 Gramophone Dreams, HR used the Elekit TU-8600S as a platform for comparing different 12AX7s and 300Bs. (Vol.42 No.4, Vol.44 Nos.5 & 8 WWW) See also: https://www.stereophile.com/content/gramophone-dreams-48-venus-tube-western-electrics-300b This also has some commentary on 12AX7 tubes per recent discussion.

The Elekit was using the Linlai Cossor WE300B tubes. The first thing I noticed after the changeover was how much softer, larger, and calmer the energy field had become. With the Linlai 300Bs, bass notes seemed more expansive and more harmonically developed than with the Mighty in either mode. Played through the Elekit with the Linlai tubes, on Julia Wolfe's Soõ Percussion album Forbidden Love (24/96 FLAC, Cantaloupe Music/Qobuz), low-frequency reverb tails were more spacious and much longer. It was not subtle. In both UL and triode modes, the EL34 Mighty played with crisper, more conspicuously detailed clarity, which distributed charged energy across a well-constructed, shallower sound matrix. With the Mighty, the quantity and aesthetic quality of reverb was always good but sometimes a little short-tailed and never the main attraction. With the Elekit, reverb was the tasty sauce of the main course. The chief difference between the 300B amp and the EL34 amp was this: The Mighty made my Falcons sound precise, like mastering-lab monitors; the TU-8600S made them sound relaxed, like horn speakers. The Mighty and the Elekit sounded more alike when I switched from Linlai's "Western Electric Replica" tubes to new-manufacture (2021) Western Electric 300Bs. The Western Electric tubes sharpened the Elekit's focus, added density and clarity, and sparked up all forms of dynamics to something closer to the Mighty in UL mode, which threw punches like a fit middleweight. I was raised in a German-speaking household by a Teutonic father who played Gustav Mahler and organ music by Bach almost exclusively. My Dad passed decades ago, so sometimes I feel a need for day-long doses of German lieder to remind me how a German voice sounds. When I do this, the first recordings I reach for are songs sung by Dietrich Fischer-Dieskau. I already knew that the Western Electric–tubed Elekit amplifier preserved Fischer-Dieskau's tone better than any other amp in my herd, so I was revved to see how the Mighty would handle that godlike baritone. I played my Made-in-Germany "tulips" pressing (Deutsche Grammophon LP SLPM 138 117) of Fischer-Dieskau singing Ein Schubert-Gothe-Liederaband, first through the Elekit and then through the Lab12 Mighty in triode mode. With the Elekit equipped with Western Electric tubes, Fischer-Dieskau's voice came out of the Falcons with gripping volume, power, and old-school German manner. The only thing missing with the 300Bs was the rugged high-relief texture of the baritone's upper registers—and that's exactly what the Lab12 in triode mode delivered, along with a wet, glowing transparency I never thought I'd hear from a pentode. I don't want to say the Elekit and the triode-wired Mighty sounded alike, but mostly they did. The chief difference was in how the triode-wired Mighty emphasized the immediacy and raw texture of the upper octaves while the Elekit directed my attention to beauties in the baritone's mid and lower octaves. The above was just from the first page or searching Elekit in Stereophile
