      I haven't owned a deck since 1985-86. IIRC, the last one was a 3 head Akai. If I was to buy another one I would pick up a NAD from the same era as the Monitor Series 7100 receiver I have. I might still have 2 or 3 tapes left, not enough to justify having one around.

      Good news for you! I never quite got the surround sound thing myself, especially for music.

      I have a Trikan and an AV5120 looking for a home, though, so I gotta ask!

      Aaah, early 16-bit Burr-Brown. Their 20s were revolutionary, and the 16s weren't too shabby either.

      I just added an interesting twist my collection: a local repair shop that I work with was throwing away some stuff, and among the pile was a pair of Grundig Lautsprecher-Box 8. They don't look like much, only ~14" deep x 7" wide and tall. I almost didn't pick them because one of the front grills was jacked, but I figured if nothing else, I could make planter boxes out of them.

      I'm glad I plugged them in first...

      I popped the back of the cabinet and found a single 6" driver with a whizzer cone in excellent shape. Folded cloth surround, so very little chance of that rotting away. Right on the back of the driver it says "45Hz-19,000Hz, so that has most of the audible spectrum covered.

      I put power to them just for a listen, expecting only good imaging and midrange. I was wrong. With Johnny Cash from the American recordings, it was like he was in the room with me. They sound great! I tried them with some traditional jazz and classical/flamenco guitar and was equally blown the hell away. I really can't believe how great these sound.

      I tried another experiment; grabbed a car audio crossover that I had laying around, set the Grundig on top of one of the Karlsons that I'd found a "full range" driver for. Ran the low frequencies to the Karlson, highs to the Grundig, and sat back and listened. An hour had gone by before I realized it. Hmmmm, I might be on to something here...

      I love it when things that don't look like they would work together do!

      My home theater is anchored by a pair of Polk Monitor 10's I bought in the early 1980's. I never felt the need to upgrade.

      It was my university system, still sounds great. That CD player was made long before 1-bit/20-bit/etc decoders... it's basically pure 16-bit 1st generation player technology and built like a tank. I always thought is sounded better than more expensive players (sometime around 1994 I conpared it to Denon and Nakamichi players and decided to stick with the JVC).
      I have a 20 bit denon made in 89. Needs some repair though. I was amazed to find optical and coaxial out on it.

      Right now I have some Teledyne Acoustic Research AR-71s, and a bunch of old quadraflex gear. I just upgraded to a surround receiver for my home theatre, so the Reference 650fet gets garage duty. It isn't the most amazing sound(I think it needs to be recapped), but the first to use MOSFET design. Came out in 1979.

      Hell's yea.
      I just started getting into Vintage stuff in the past year after years of digital equipment.

      So far I am:
      Marantz 6300 turntable (Fully restored by Claudio at www.vintageturntablerestoration.com)
      McIntosh MX110 w/ Telefunkens Found on CL for $300!
      McIntosh MC250 Restored by Terry Dewick
      Klipsch KG4's, and some old Bozak 130's (I really want Heresys or cornwalls some day)

      I also have a Marantz 2265b (

      Anyone every play around with Dynaco amps? Specically the ST-70?
      I've been interested to hear EL34 tubes in something other than an guitar amp.
      You can pickup one of these new reproduction kits for about 700 or for around 1000 assembled.
      Dying to hear one....

      ^Yup thats the PS-10! Feturing the high freq. crossover in the back. Very cool.
      I got my pair with a rotted woofer for 25$! The replacement woofer (only a pyle 1000w woofer was shallow enough to fit that box) was 80. Still not bad, they sound great and fit under my end tables!
      The Misses would never allow for a full size 3 way with a 10" otherwise. It was a score in my book!

      The 'I rebuild marantz' website has full bulb kits specific to your model. Saves a lot of time trying to find the sizes and voltages on each bulb. The kit I got even included shrink wrap and little strip of solder for the bulb on the tuner indicator that has the wire leads.
      Be careful not to break the little brittle plastic bulb holders. I did, it is almost impossible to remove those bulbs that have been melted in there for 30 years.

      I shied away from the LED conversion, I didn't want my receiver looking too modern, like it was about to take off into orbit.
      Audiogon website is a great classified too.

      Cool to see Vortex-ers with appreciation for 'real' quality audio!



      I haven't touched my $400 Nano mp3 player in about 2 years now.
      I almost wish mp3's where never invented as the mp3 will be all this generation knows, most likely.
      And that is sad.

      Sometimes more modern isn't an improvement. In the case of 95% of CD players, they sound worse than vinyl. The MP3 players are even worse than that. It's been 28 years since compressed music on CD started the trend to become the norm. There are millions of people out there under the age of 30 who have never heard vinyl. It would be interesting to do a blind A/B session with a group of them to see if they could tell which one they were listening to.

      I'm not taking either side with respect to sound quality but... CDs are not compressed. They contain an uncompressed digital (but not precise) representation of the analog waveform.

      Though with respect to "28 years", one could argue that compressed audio has its roots even earlier than that in analog tape. Dolby noise reduction (and the other similar systems back then) are compress/decompress systems.

      Compact Discs are not compressed.

      I can see why someone may think a CD is compressed due to the fact that CD's do not contain a 'full recording'. CD's are digital 'samplings', just like Mp3's (but mp3's are a sampling of a sampling, so they represent even less of the original recording)

      A CD wavelength is 'jagged' or 'stepped' compared to the original from which is was taken.

      CD's do have a larger spectrum than vinyl, but have less music 'data'
      Vinyl has more 'data', but doesn't have as wide a spectrum as CD

      This is what makes CD's 'dry' and 'loud', and vinyl 'warm' and tonally 'full'.

      Listening to Suicidal Tendencies self-titled album through 4 Sansui SP-2000 speakers and a Sansui QRX-7001 Quad receiver right now. Ahhh...

      Getting ready to test our "Wall of Sansui" featuring three pair of SP-2000, two pair of SP-200, one pair SP-2500, one pair SP-3500, and an SP-30 (can't find the second 30).

      Terrible cell pic:



      (two SP-2000s in their original boxes not shown in that pic)

      They have all of the drivers.

      Technically, the CD vs vinyl thing depends on what frequency band you're talking about. At lower frequencies, CD is more accurate. The crossover where vinyl is superior is up around 1 kHz but they're quite close up to 5 kHz. Middle C on a piano is about 300 Hz. The top note on a piano is around 5 kHz. As the frequency gets closer to CD's 40-ish kHz sample rate, you get more and more distortion. At 5 kHz, you get 8 samples and that can fairly accurately reproduce the sound.

      I'm old enough and listened to enough loud music in my life that I can't hear the difference.

      Just for clarity, the 44.1 kHz sample rate doesn't reflect the maximum frequency the audio sampled on a CD is capable of. It's limited to 22.05 kHz due to the Nyquist sampling theorem (essentially, the sampling rate has to be 2x the maximum frequency).

      Age as well has not been kind to my hearing on one side though... at this point I'll settle for accurate reproduction w/o sweating about theoretical limits and worrying about analog vs. digital.

      Well, for the fundamental frequency at least... you'll also be getting a few more samples on the harmonics but your point is still valid.

      SACD tried to address this with a much higher sampling frequency but it never really caught on. I suppose that was because while audiophiles were arguing the public discovered MP3 and Napster.

      My engineering training is in digital signal processing. I laugh when the audiophile rags talk about Nyquist. You can't accurately reproduce a 22 kHz sin wave with a 44 kHz pulse coded modulation sample rate. You get a saw tooth. Take a signal generator and feed a sin wave and a saw tooth into a speaker. They sound very different. When you overlay multiple frequencies, you end up getting all kinds of false harmonics. With PCM, you really need about 8 samples to come close. Voice telephone networks sample at 8 kHz. That's why women sound so lousy on the telephone. A lot of their signal is above 1 kHz and it distorts like crazy. A man talking down at 300 Hz sounds fine.

      I honestly can't hear the difference between CD and SACD. Maybe when I was 16, I might have been able to. I work a lot with wideband voice codecs that are designed to do telehone calls with frequencies up to 7 kHz instead of the 3.1 kHz in today's phone network. With women, you can really hear the difference.

      I can definitely hear the difference between MP3 and CD. MP3 isn't a very good compression codec but the patents go back to the 1980's and have mostly expired so everybody uses it. Nobody wants to pay the royalties on a better codec and when you put MP3 in consumer products with a sub-$10 bill of materials, you're not going to use something where you have to pay any royalties. G.722 is the same way with wideband voice. It's not the greatest codec but everybody uses it since the patents have expired. I've been sucked into patent litigation enough times to know that you don't want to do anything that steps on those kinds of patents. A judge can shut your company down.

      I just got this yesterday, an Elac Miracord H50.





      Sounds great compared to my basic Pioneer PL-10. I just hooked it up and it was good to go. Direct drive so no belt to replace. Its nice that its fully automatics, although I haven't got the continuous multi record thing to work.

      Too cool! I actually just had someone email me earlier this morning looking for an H50 or something similar. The 770 is "the one to have", or so I've been told, but as long as it sounds good to you, rock with it!

      I dragged home another amp last week; a factory-built Hafler DH-120. Super-beefy 60 WPC stereo unit, built back when David Hafler was in charge. It's no monster, but has current output for days and will drive my home-builts (~93dB efficient, ~5ohm static load) very nicely.

      I also have the Elac brochure. The line up went like this: 620, 630, 50h, 750, 770H.

      I'm not going to type it out all out, but basically it has all the same features of the 50H, plus you can set the speed precisely as 33 1/3 or 45, and a stroboscopic ring on the turn table will read out the speed in numbers. Or you can vary the speed as much as 3% either way. You can also adjust the angle of the stylus up to 15 degrees for when you have a stack of 6 or 7 records waiting to be played. Oh, the retail was $175 for the 50H less base and cartridge, and $225 for the 770H less base and cartridge.

      This was my Grandfather's. Hasn't been used in years, so I'm not sure if it still works. Anyone familiar with the model or brand?

      Centrex (Pioneer) KH-767. It's in pretty good condition, now I just need some speakers.
