  1. Crazy good amp. I finally have speakers in the family room and the great compromise was SS amplification. This unit was special ordered with a not advertised PS upgrade from Nick... better Caps and resistors.
  2. Thank you. They are built like a tank.
  3. Yes I have 4 built but never assembled cabs.
  4. I try to separate what I do personally vs company. At my core, I love Klipsch products and audio in general. This way people cant say Im Hawking my stuff on Klipschs footprint.
  5. Cornscala horn speaker - ampsandsound Hudson For sale is a new Cornscala 3 way horn speaker system. Selling off my newly built Klipsch style Cornscala's which are modeled after the famous Cornwalls and and built by staff at ampsandsoud. Exactly the same driver compliment as the ampsandsound Hudson. All parts are new. For those who don't know a Cornscala utilizes the best parts of a Klipsch Cornwall and a La Scala together.
 Cabinetry is done with Baltic birch and utilizes biscuits and additional bracing for strength, reduce distortion and resonance. 3/4" Ply with ¼" MDF for a perfectly flat, no resonant surface. Each panel is 1" thick. All braces and back panel are secured with ¼-20 fasteners. Black satin lacquer. Gorgeous on the eyes. Low frequency driver includes massive direct radiating 15" woofer for bass. This is the same woofer use in the Klipsch 904 and in the Cinema line. The woofer's weight rests on its shoulder and not its face to increase rigidity and minimize basket flex. The additional double motor board around the woofer provides isolation and the rigidity needed for truly chest thumping bass.
 Midrange horn is sourced from fastlane audio Eliptrac 400 with Fc@ 350 and being crossed @ 450hz. Midrange driver is the famous B&C DCM50, Paper Diaphragm material and incredible 400hz usable range. The Tweeter is fastlaneaudio Contrac (Conical Tratrix Horn) paired with B&C DE-10 Mylar diaphragm crossed and 5800hz will outside of the range of the human voice. Crossovers are ALK CSW-450 which is a custom licensed crossover, combining the AP12-450 and the cornscalawal high frequency section. This is a significant improvement over a stock cornscalawal as it proved a 12db 2nd order crossover on the bass thus providing tighter and faster bass response. All internal wiring is silver plated teflon. This is master piece of a project and far more than the sum of its parts. Cabinet: 34"H x 24" W x 16" D
Weight: 145lbs/per cabinet Frequency Response: 34Hz - 20Khz -3db, 98db
 Sensitivity Willing to ship via road freight. Extensive experience transporting via road freight, reasonable pricing. Justin 323-868-9722
  6. The speakers in the ad are not the same as the Hudson. Different cabinetry, driver compliment/crossover and finishing. They are amazing sound in their own right but not the same. Re speakers, ampsandsound generally only builds on spec at this point. Most customers like being able to chose exactly what they want. I however, love building speakers... as I have done for many years, I still build about 2-3 pairs a year.... listen and sell off at a reasonable price. Ive taken to changing the ports to differentiate these more clearly now... triangle ports. As an side, Ill be listing a pair of my personal speakers later... Finally need to complete a pair of my Royals... JWC Bass bins with Daves horns. Its been sitting in my garage staring at more for far too long. Time to own a pair of the big boys.
  7. Bought a pair that were never used. Installed and tested, have less than 1 hour of use. Ive compared the BMS 4592-Mid to the Radian 950Be, B&C DCM50 and yet these were hands and feet above. Price is firm. Nearly impossible to from US speaker had to wait 6mo before they came in. Justin 323-868-9722
  8. Id love the arm if you can measure the pivot to spindle distance.
  9. Hear are a few Ive tied and thoughts The very best ever head... BMS 4592 Mid 2nd. B&C DCM50 3rd. Radian 850 with Be driver.... sooooooooooooooooooooo hard to work with.... tuning it might kill you but if you get it right its an amazing choice for 2way. B&C DE750.... its a monster... no brainer choice... will make you think you have better bass. Heavy... horn will need to be braced. Fatial HF140/200. Sings... goes low... goes high... light no complaints... everything is right. Nothing disappoints but nothing blows you over.., no weight issues. B&C DE85 Smaller version of 750... less impressive... Like the HF200 Had a Pyle what was a parts express closeout... its was a close of a PV or JBL.... huge... like stupid big.... inefficient as compared to the rest. But sounded great... practically gave it away and went to 400hz.
  10. John, Feel free to give me a call. I might be able to help. 323-868-9722 justinsweber@hotmail.com
  11. Ive tried the original spec and the revision... biggest difference was total power out. The original power supply was terrible. If you look on the DIY audio forums... this mod had been around for a long time... perhaps as a workaround for the poor performance of the 19V? The amp section is incredible, but the laptop supply leaves much to be desired. Building a linear supply is pretty simple but if willing to do so, perhaps the F5 or F6 would be a better choice. I left such endeavors to ebay as I have. Regulated linear supply was my ticket. The orig ACA were monos... love that. The current ACA is a dual mono single box unit. which can be doubled for monos. In short... if wanting a project... the ACA is definitely a hot ticket. If wanting reference sound... need to upgrade the power supply. For must of us, a 5-8watt amp is all we would need... the rest is sonic presences.
  12. Ive heard at several shows at they were amazing. Can speak beyond that, but at the time under show conditions there were impressive... never in a large room but still impressive.
  13. Bob Crites has a new 600hz horn. Has anyone tried. It would be a nice upgrade to anyone with a K701 (Plastic horn) with bolt on driver. Super cool for doing Bob!
  14. I liked enough to have the ACAs come home.
  15. I would have though he would put them in the top hat. I left room. but to each their own :-).
  16. They are. He added the ES5800 and the tweeter. Loves them.
  17. I contine to have a soft spot for the LS. The Khorn can sound amazing, but placement is a real consideration. I have Jub clones. Likely the best speaker Ive very head... ALK crossovers and all, but the sheer size killed them off. Folded horns have a legitimate place in the order of things, but when balancing size and performance the size question becomes the weak link. The Sunn speaker looks like some bad PA close stuff I see all the time with DJs.
  18. I have 3 pair of the mino punches. They were easily better than k horns but not match to the jubs. With the CSW45O that is jub/mini punch compatible they tied the Jubs. Dig deeper. JWCs design is horn loaded with a tratrix flair and ported. Total pain in the *** to built but a real contenter to the jub/k402 combo. And more importantly... so much smaller. 104db if I recall.
  19. Ive grown to appreciate pull designs more and more. SET amps (forgive the implication) are like a C*ck tease. All the tone/sound you could ask, but never enough of it. Well designed SET amps can be just as quite as any other design, its the lack of significant horsepower that becomes a consideration. If in a small room or not trying to see how loudly you can play, SET amps are incredibly pleasing. But, a P-P amp has some feedback which will provide its own benefits. All the sonic benefits you find tubes in general are offered in great abundance with P-P designs. Im not a fan of Parallel Push Pull or Parallel SET but there are reasons for that... Ill leave it at the KISS approach as rule outs. Class A SS badass. SET Badass but not enough for most of us. P-P Tube... just right. (Dynaco ST35/ ST70, Rogue Chronus, MC275, nearly any KT88 P-P or EL84 P-P )
  20. Different amimals all together. Though I respect pass designs. I’m decidedly a tube guy. Sold guys
  21. Donating these to my daughters school. Need a pair or scalas for refurb. Thanks justin 323-868-9722
  22. Selling off an early prototype of the Agartha. Bases on the the GSE from DIYaudio. 6B4Gs for output tubes, 6AX5 rectifier and 6SL6 front end. All NOS, ALL US tubes. Includes functioning VU matters. 5watts SE tube goodness. Price is firm. Justin 323-868-9722
