Like The Bass sounds like Red wine or The "headphone cables sound fast", 90% of the speed of light

ELP ish...

Keep the c80, no brainer Buy a Yamaha MX 600 or MX 800 and re-cap the unit. World class amps You will have great sound compared to anything no matter the price

Where are you located ? I would look at Quality used totl 70-120W AVRs in the 10-20 year old range Most of these are high quality AB Amps with huge power reserves for dynamic response. No matter how good they sound, they don't sell for much. Turn off all of the surround stuff and run it as a stereo in direct mode If you get them cheap enough buy 3 or 4 as they come up and see which one you like best Nice toys if nothing else

Specs on it are OK CXA60 Integral DAC, would expect better SN Maybe everyone measures a little differently If the price is right, drive it for six months and if you don't like it, sell it I've picked up 5 AVRs that are great performers for around $60 total The reality is that 15 year old AVRs have little resale value, no matter how good they sound. I would check CL and local resale shops too Even a Little basic 1995 SONY D565 I picked up is in the ball park spec wise $14 Even has a great tuner section. Phono input, no DAC Basic tone controls and bass boost button I did pay $20 for a stock remote, Sony has their own multi unit remotes too new. I bought it for my daughter who I'm trying to ween off of earbuds, using it in my basement for now. I blow them out with a compressor, check the solder joints and caps for leaks, and spray cleaner into the dials and buttons, miracles frequently occur https://www.hifiengine.com/manual_library/sony/str-d565.shtml CXA60 Detailed Specifications Power output 60W RMS into 8 Ohms 90W RMS into 4 Ohms DAC Wolfson WM8740 Frequency Response <5Hz – 60kHz +/-1dB THD (unweighted) <0.002% 1kHz at 80% of rated power <0.02% 20Hz – 20kHz at 80% of rated power Max power consumption 600W Standby power consumption <0.5W Analogue audio inputs 4 x RCA, 1 x 3.5mm MP3 input (front panel) Digital audio inputs 1 x S/PDIF coaxial, 2 x TOSLINK optical, Bluetooth via BT100 (not supplied) Compatibility TOSLINK optical: 16-24 bit, 32-192kHz (using high quality TOSLINK optical cable) S/PDIF coaxial: Linear PCM 16-24 bit, 32-192kHz BT100 Bluetooth receiver: A2DP plus aptX Outputs Speakers A+B, 3.5mm Headphone, Preamp Output, Subwoofer Output Headphone output THD: 0.002% (1kHz signal, 1V input, volume set to 1V HP output, 80kHz bandwidth, into 32Ohm load) S/N: dependent on volume pot position.

If you wont fry yourself A box of totl outlets and switches isn't a lot of money same for a basic outlet circuit tester polarity and gfi For a few bucks more, you can get an EMI detector at the HW store You can go around and change them all out inc adding GFI outlets next to water Totl are like $1 more than junk outlets in builder packs

Since you asked 820C produced in 1956 30 HZ - 22 KHZ 16 Ohm 30W RMS 230 lbs 1956 Price $ 525 / $35 Oz gold = 15 OZ 2021 Price is $1900 x 15 = $28,500 http://www.cieri.net/Documenti/Cataloghi/Altri marchi/Altec - Catalog 1964.pdf Driver specs on brochure Curves for the drivers are easy to find with a search

Claude Are you the same guy that has an entire thread on a product you designed and built ? Your horn is certainly not a Klipsch product. If you delete your horn thread and all of the comments I will delete the photos of the non Klipsch speakers you don't like Let me know when you have finished deleting your thread

Mostly what I like are the vocals and acoustic, don't know if its because of the LaScalas or the reverse ? I did pair it up with a Klipsch RW12 front firing sub, and definitely more bass at the lower range. Mostly leave it off for what I listen to. Both JBL and Altec made some great products. Haven't heard the ones you mentioned. A lot of the Guys in the Mac forum AK were worked up over the 4350s, some managed to score some Altec 820C was very impressive when I auditioned a pair, if I had room I would have the cabinets made and install some drivers. 811 horns. I thought they were a little shrill, might have been the amp, but was unable to swap amps. Great tight bass. 820C fully horn loaded, drivers aligned. 2x15 all Alnico magnets.

Totally agree Klipsch understood declining marginal returns It's the reason the company and designs are still around. 1% improvement at double the cost is a business killer Just out of curiosity What other large speakers are you referring to and what types of music

Yeah One of the big review sites the editors can hear the difference with fast and slow headphone and speaker cables Freq sweeps of 16GA Lamp cord and Gold cables, likely are identical

My wife yelled from upstairs and asked "Do you ever get a shooting pain like someone has a Voodoo Doll of you and they are stabbing it" ? I replied NO ! She Responded "How about now "?

Directivity I'll have to take a look for horn geometry and effect on directivity and interference Not sure how far away you have to be for free air dispersion to become noticable Certainly it becomes an issue with a vibrating cabinet, or walls etc At least I have some new video channels to watch for the winter

Dispersion Demo using a spring Dispersion on a Black Board, free air calcs are different than solids or liquids Not sure how far away from a LaScala you have to before dispersion effects the noticeable sound quality. The solids demo could be speaker cabinets that vibrate.

Blue Horseshoe likes Wall Street Better than expected Excellent production quality video and sound

Welcome to the party Horn loaded on all three drivers with roughly equal dispersion and phase Mids are at ear level sitting. Crossover point was 400hz on the mids which puts almost all voice energy on the mid horns Atlas was I believe the original Compression driver OEM for the mids, they built a great driver which Klipsch foolishly walked away from in a cost cutting more, when he went back to Atlas they blew him off. Unless you block them with a bookshelf, they sound great anywhere. Guessing they were for theaters where sound is everything, turns out they are great in any size room. Industrial versions were also produced, different industrial finish. They came in raw birch plywood, veneer was an option; which I ,like most people, skipped for cost reasons. I purchased mine instead of a car, and have never looked.

The outboard switch has no power of it's own to power the relay switch I don't know if the AVR trigger socket is intended as a power outlet via the tiny plug or just a signal device that goes high then low The required current is 12VDC, 100 milli amps

After years of staring at the 12VDC connectors on my receivers I have decided to plug one in to a Niles SPK-1 AB speaker level switch What do I use for a cable ? Standard 3.5MM headphone cable ? If the connector is unique, where do I find them ? or Do I need a 12VDC power supply plugged into the switched outlet on the back of the Amp?

25 years is the life of a capacitor So yes it's time Crites has caps and replacement crossovers, some with bi-amp option Others offer similar
