    Cables, Coffee, Cycles, and Cocktails

    in Lounge

    Posted

    While browsing another forum, I came across this post:

     

    "This is the LAST ever B-stock version of the $200,000 Hyperspace Supernova Clear 2m!  It's a brand new build but with slight cosmetic flaws, and red wiring for the ground instead of green. Very limited edition, only 3 of this cable has been built! Sold for 100th of retail price! "

     

    Since I'm looking for two cables and there is only one, I guess I'll have to spring for the non-B stock...:pwk_bs:

    FS: Spendor SP1/2R2 Loudspeakers - Sold

    in Garage Sale

    Posted

    You read the tag line correctly. Try this pair of Spendor SP1/2R2 speakers for $100.  Two, but one is dead. We think it’s the low frequency driver voice coil, but could also be the crossover. After attempting to work with the dealer, tech & distributor for nearly a year to repair, I have reached my limit & wash my hands of it. The other speaker is fine and if nothing else, would make a great center speaker.

     

    Cosmetically, they are in great shape.The cabinetry is ebony veneer with the usual minor dings snd small scratches you get over 7 years. The grills are snag & pill free.The bases are a bit rougher from resting on metal  stands and movement. Frankly, they’d sit nicely in a living room.They are already packed in the factory boxes ready to go.

     

    Given the 40 pounds per speaker, I’d suggest pick up (I’m south of Nashville TN), but they can be shipped anywhere of you pay the freight. The specs are below:

     

    F Drive Units: 19mm soft dome, ferrofluid cooled (0.75") Scanspeak 2008
    38mm soft dome, shaded pole (1.5") Scanspeak 3806

    LF Drive Unit: 200mm polypropylene cone (8") 40 mm voice coil (1.5")

    Impedance: 8 ohms nominal

    Sensitivity: 88 dB for 1 watt at 1 meter

    Maximum SPL 104 dBA at 1 meter

    Crossover Points: 3kHz, 13 kHz

    Frequency Response: 45 Hz to 20 kHz (+/- 3dB)

    Pair Matching: Within 1dB

    Power Handling: 100 watts

    Cabinet Dimensions: 635mm x 300mm x 300mm (25" x 12" x 12")

    Cabinet Weight: 18 kilos (40 lbs.)

     

    Please feel free to email any questions. Thanks.

    SOLD: Electro Harmonix KT-88s

    in Garage Sale

    Posted

    Two (2) matched quartets of Electro Harmonix KT-88s. One quartet is new in the box, never installed. The other was just pulled from my amp. These tubes have about 250 hours on them with no issues.

    Tubes have black lettering, metal bases. No logo except on the box.

    I went back to 6550's and much prefer the sound in this amp.  $100 plus shipping for all 8 tubes. How's that for a deal?

     

    Please let me know if you have any questions. Thanks.

    Since I cant put pics up let me see if my link to my craiglist ad works - and if some one can show me why pics aren't loading - I'll put the pics in.

    The link works, but MDF is really not "particle board." Low density Fiberboard (LDF) is generally referred to as "particle board" or "chip board;" not to be confused with Oriented Strand Board (OSB) which looks like it should be called chip board.

     

    Just saying after 23 years in the forest products industry...

    PS: Not debating the merits of any products' use in speakers; the designers have done that. B)

    How did you discover Klipsch speakers?

    Its complicated...

    My father & PWK received their EE together at Stanford. Dad was with Jensen & CTS and followed what PWK was doing. I grew up with a loaded horn in the living room...  

    Then I married a gal from El Dorado (two counties SE of Hope); her parents were from Hope & I met PWK in 70 or 71. Heard K'horns then and have never forgotten my fascination with their sound.

    I would think he would gain in owning a pair of Jubilees ---or even khorns

    Sonically, yes. But looking at his wall & cabinet neither would be a particularly good fit. I faced a similar quandary when I wanted K'horns (still do). No corners and no place for false corners.

    Sometimes you have to work within the physical constraints of your home.

     

    Why haven't we suggested he build an acoustically correct addition to his house? :laugh:

    Having followed this thread from your telling title, my two cents is return them. You are obviously unhappy & second guessing your purchase. You got off on the “wrong foot” with the disconnected tweeter and that negatively flavored your impression of the speakers since even though they appear to be functioning properly now. It's likely nothing will get that from the corners of your mind. I still have that attitude about a particular model car I bought years ago regardless of its current reviews and stature.

     

    As you seem to view your Heresys favorably; consider swapping the La Scalas for a set of Cornwall IVs. You still get a “big” speaker that is not overpowered by the scale of your cabinet, has almost universally praised sound quality and you get about half your money back,. What’s not to like?

     

    The added bonus is that in a few weeks, someone can get on “open box” deal on a pair of walnut AL5s from Crutchfield.

     

    Just remember, all this supposed to be fun.

    Yep. Up until then Fauci said they weren’t necessary.

    Not quite: from Politico on 3/31 (and numerous other sources):

     

    Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, revealed on Tuesday that the White House coronavirus task force is seriously considering guidance that Americans wear masks to help thwart the rapid spread of COVID-19.

     

    But the country’s top infectious disease expert also acknowledged that such a directive has been complicated by the nationwide dearth of personal protective equipment.

     

    “The idea of getting a much more broad, community-wide use of masks outside of the health care setting is under very active discussion at the task force. The CDC group is looking at that very carefully,” Fauci told CNN.

     

    “The thing that has inhibited that a bit is to make sure that we don’t take away the supply of masks from the health care workers who need them,” he continued. “But once we get in a situation where we have enough masks, I believe there will be some very serious consideration about more broadening this recommendation of using masks.”

     

    And don't forget the Taskforce includes 21 other individuals.

    Twitter has suspended the account of a Colorado biotech company which is working with Cedars-Sinai to test and develop a potential coronavirus treatment using UV light inserted into the lungs - the same week as Homeland Security's head of Science and Technology, Bill Bryan, suggested that UV light could have a significant affect on viruses such as COVID-19.

     

    .

    Here's a link to an CFP's analysis of Aytu:

     

    https://seekingalpha.com/article/4338518-aytu-bioscience-corona-portunist-40-downside

     

    "Before entering the Coronavirus testing market, Aytu BioSciences was an aggregator of marketed products with little penetration and, in my view, poor growth prospects. Its only existing testing product is an aid in the diagnosis of male infertility that is not approved for sale in the U.S. Management has quickly moved to bring a Chinese COVID-19 test to the U.S. market under emergency relaxed FDA guidelines." [emphasis added]

     

    From Autu's website describing themselves: we bring novel and needed treatments to market and to the millions of patients that need them. Novel products that can really help people feel better...

     

    "only existing testing product is an aid in the diagnosis of male infertility that is not approved for sale in the U.S." & "novel" sounds like the forefront of medical investigation to me.

     

    For the record,  YouTube also pulled most of Aytu's promotional videos as well.
