    The Long Overdue Death of Retail Compact Disc

    I consider cd's as a safe digital back-up system. If your music device breaks or your laptop gets stolen etc. you always have your back-up cd's. Downloading music from the internet takes your power and and rights away from ownership. I would place close to zero value in this. They'll get $.05...

    Need Advice With Drivers And Crossovers

    It sounds like you want high power handling speakers. I would suggest you look at the ones you might purchase at US speakers and a couple of other pro audio speakers than can handle that kind of power. The other thing is that if you have a 15 inch woofer you need to find out what the...

    Does low quality audio damages Hi-end speakers?

    Combination of both...two much power and too much nasty distortion happening together. Most people have the common sense to keep this from happening but every now and then when changing volume settings accidents can happen.

    The main site is DAR, http://www.digitalaudioreview.net/ I didn't know some countries are not authorized for vimeo as DAR is fairly international. So that's new to me. Whether it's 1,000, 5,000, or 10,000 its just an example of how savings can add up as the number gets larger. I was not...

    The question was rhetorical in nature to show a possibility. some consumer electronics areas are bigger and more lucrative. To give you an example I found a video of Ayre acoustics and they do 20 products a day. Giving a conservative estimate of 400 units per month thats 5,000 units of whatever...

    Sony 75 inch 940d or Sony 65 inch ZD9

    all I can say is ouch...I bought the sony 55xbr850c a year and a half ago for $1100 with the x1 processor and I've been very happy with it. I don't know how happy I would be paying $7,000 for a tv and a year later you can get it for $3,500 on closeout. Paying for R&D is a bitch...

    Maybe...but if I was a small company and I can save $50 on parts and $25 on shipping and handling and sell 10,000 units per year that's $750,000 extra dollars in my wallet (after ten years it's more than $7.5 million). You might not care what happens to your product when it starts failing after...

    If you can't get satisfaction from a $10,000 amplifier or even a $5,000 amplifier it's time to work on getting better speakers and a dac (Vinyl's not my thing).

    That's why I gave it a minimum ten year life to be fair and conservative to smps power supplies...but like you said more often than not a linear power supply lasts 20 years...the transformer failure I'm not sure how frequently they fail but its gotta be much smaller than capacitors.

    Interesting link. Thanks...I think the real question is longevity linear vs. working harder smps. Also, you can use smaller and quieter transformers with more capacitance in the linear power supply.

    If the smps can last 10+ years with heavy use then you may be right...what percentage of linear power supplies have failed vs. smps supplies over a ten year period? Is there a statistic? Maybe they've figured out how to get smps supplies to last 10+ years by over engineering them then kudos to...

    I just did a search on digikey and the Panasonic T-ha are listed as obsolete. For the money they we're the best...I found out about it 3 months ago when I did a search and then inquired directly from customer support. Panasonic still produces capacitors just not large Power caps...I think its...

    I think we're dealing with Bic disposible products now below a certain price point. What I'd like to know is who's got good power caps now that panasonic is no longer manufacturing quality electrolytic power caps. suggestions.

    They might not care about longevity anymore. Emotiva switched to smps on their new amps and their warrantee period is now down to 3 years. Good luck when your amp goes down after five years and your linear power supply lasts 20 years.

    I think if there is a hell they should make all those japanese executives try and power their premium JBL 4350s with cheap japanese receivers. If its good enough for americans its good enough for the japanese....couldn't resist.

    I think more capacitance in the power supply design.
