  1. So I have the C6 cleaned and serviced last year locally by a reputable technician. Still have static in the switches/controls. The Parametic EQ section is creating some static and the turntable left channel is singing like the low roar of a hot fire.

    O wait, it gets better.....I also detected an audible hum in my outboard EQ too. So now I am running a flat signal and have no B&O to operate. It took me (2) hours to verify the source(s) of these problems. The B-2 network upgrades definitely improved the signal from approx. 2.2hz - 7K IMO on the Cornwalls. A little bit more in dynamics, but not much.

    Since I see that BB (Best Buy) now sells Yamaha, I guess I'll have to check around and find a LEGITIMATE technician that can CORRECTLY FIX these issues.

    Sorry, just tired, dissappointed and frustrated from working on this system from 1am to 5am!

  2. One issue you bring up is current. Actually RCA's are used in high impedance circuits. That means that in Ohms law: Impedance = Voltage / Current. Voltage is low, about 1 volt. This means current is very, very low.

    I know my automotive setup is pushing a 7v preout from my EQ to the amps, and almost performs as a line-driver, so I figured a pro-series set of RCA's would maximize my output. I have to keep switching hats when we talk AC/DC (lol).

    O, and let's not forget impedence differences too! GRRRRRR!

    Thanks for the responses, and I have some mediocre RCA's for the home system, but figured I'd ask.

  3. First, can someone answer this question? What are the basic differences between home audio and automotive(aftermarket) audio RCA's. I was under the impression that products like Stinker and Tsunami would be of higher grade since shielding and current needs are greater in the automotive application.

    Having said/asked the question, I intend on firing up the ENTIRE system this weekend w/my rebuilt B-2 networks (courtesy of Bob Crites). We only have CC (Circuit City), BB (Best Buy) available for accessing high-quality RCAs.

    If you see my sig, please guide me toward obtaining a GOOD set of RCA's that won't bankrupt me.

    Thanks

  4. I do know MECA uses 95db as the ceiling for SQ testing, and we also have restrictions on SPL testing levels. Requiring either an outboard (outside the vehicle) operating HU, or hearing protection if operating within the vehicle.

    Good advice as aforementioned, but when you're young and stupid, well.........what more can be said!

    Why only (1) ear? Generally speaking, as with vision too, very few have 50/50 (matching) levels. Most people have a stronger/or weaker ear/eye.

  5. My grandmother had implants before 50, along w/my mother who both experienced hi-freq loss, and certain low mid-bass loss too.

    How on Earth I managed to attend 40+ concerts and run lights for a local band, and STILL have good hearing is beyond me, but value this precious gift. I know I don't abuse my hearing anymore.....well, not too often! (lol)

  6. You are buying their patents and name..........throw a little DSP in the mix and up the price![Y]

    I like the 3-2-1 system, but about 2x overpriced IMO. Yes, I do regret WASTING that much money on this unit, and the worst part is I cannot play MP3's or DVD re-writes. SUX!

    Works well for the Big Screen, but that's about it!

  7. Colterphoto1:

    Yes sir, purchased unfinished Birch w/specific intent on staining them myself to match my living room furniture and surroundings. Glad I didn't urethane them though.......and still holding up nicely.

    Soon as I get my networks back in, and everything hooked back up I'll snap a a couple of pics of the entire system w/my 56" Big Screen

    Back to topic, OUTSTANDING writeup and explanation, and if I can follow it, anybody can!

    GOOD JOB and thanks

  8. W/O getting too far off-topic, here is another interesting observation:

    In MECA, we formally used a Focal disc for testing SQ, and now are utilizing the Cheskey Sampler. Just so happens, there are (2) tracks on both CD's; however, the Focal "Grandma's Hands" (Livingston Taylor) has a pronounced/detailed footstomp, whereas, the Cheskey is much more subtle, which is indicative of the re-engineering.

    We have gotten into more arguments over WHICH (if either) is the properly engineered recording. With so much processing used these days, it is hard to determine WHAT IS THE ORIGINAL/NATURAL reproduction.

    This again, stems back to the source and how the recordings are manipulated.

    I was actually re-tuning my car one day, and accidentally tuned my system to the point where I could audibly hear the low rumble of an A/C unit during the lulls of a sax solo. This was NOT a natural phenomena of the recording, however, I use this example to illustrate the ability to create artificial (non-intended) sound reproduction as a result of technology.

  9. I have witnessed first hand what sound surround can do in an automotive environment....specifically, the Alpine F1 and soon Harmon's 7.1 JBL MS-8 model (prototype).

    Certain tracks, depending on engineering, and surround settings can down right sound unrealistic. I would think the source disc would have a major bearing. I cannot condense the explanation into a brief summary, but let's just say sound surround is an enhancement that doesn't always realistically image properly and/or loses detail in certain portions of a given track.

    This is a highly controversial topic and subject to a slew of different opinions, but IMO, vinyl still on a freq/dynamics scale, can reproduce better than CD/DVD simply because the highs/low are not digitally eliminated. Through audible occuity (being able to distinguish the two mediums), you should be able to feel/hear the realism over digital recordings. Take it a step further, and evaluate a "Mastered" Album which were high dollar back in the 70/80's, but superior in sound.

    If you want a real challenge, try listening to a "BEST OF" CD of any artist/band bridging the late 60's to 90's, and hear the engineering improvements from the early release to later year recordings.

    Example: Elton John, Rolling Stones, etc.

  10. I've seen the Cambridge, but not too familiar with them. As for the Sony, it was an entry level, average grade unit, but I am seeking 16x oversampling, 24 bit burr browns, etc. -- something with a little more bells/whistles and refinement.

    Heck, I use my Sony Walkman and Sennheisers for tuning my car sometimes, and also have a 25 year-old 21" Color Sony TV still working in excellent condition.

    I just think I can obtain better sound that will compliment my system.

    Thanks for the tips!
