  1. I wouldn’t know. A buddy of mine wears two. He says that they cost US$7000 EACH! He also complains about how terrible music sounds with them all the time. He says that he has never heard a hearing aid that sounded any better than “music on hold” on a telephone. I don’t wear one myself, so all of this is just hearsay, but it’s hearsay from everyone I have ever known who has worn a hearing aid. If there is a good sounding hearing aid that allows one to enjoy music, I’ve never heard of it.
  2. Hearing and listening are two separate, though related, things. In hearing, people's frequency response differs according to age, sex, and environment. For example, a 12-year-old girl can likely hear 22kHz and perhaps a bit higher. OTOH, a 60 year old man (or perhaps a 30 year old who has been exposed to high SPLs such as a boiler factory at work, or too many live rock concerts) may have frequency extension only to 14kHz or even less. But this doesn't really alter most people's ability to hear and appreciate music. But trained listeners (such as "golden-eared" audiophiles) have trained his/her listening acumen to notice things in a musical presentation, that most ordinary listeners would not notice (nor care about, for that matter). Sight is different. Advancing age, of course, changes ones sight as well as one's hearing. The difference is that eyeglasses can correct many age-related sight problems such as near-sightedness, farsightedness, astigmatism, close focusing, etc., and compound glasses can correct several of these things at once. However, there are no prosthetic devices such as hearing aids that can bring back one's lost high-frequency response, and the hearing aids that are available can only bring back some of one's failing ability to hear everyday sounds such as speech. From what people using hearing aids tell me, even the best, most expensive hearing aids have lousy frequency response and make music sound terrible.
  3. Your guess is at least as good as mine. If the tapes were momentarily over-modulating on peaks, that can result in clicks every time the record volume exceeds 16 bits or 100% modulation (0 Vu). Other than that, I can’t imagine what would cause those clicks (I have encountered that phenomenon before, however).
  4. Four of what, the Motion 4i speakers or the Napa Acoustic 208A amp?
  5. Broken, non-functioning amplifiers are the only thing that can improve rap
  6. I think the Napa Acoustics 208A is $399 (at least it used to be. Their website is blank right now!). But if you go on alibaba.com you can get that same 25 WPC hybrid amp (dual triode front end, solid-state output) directly from China for far less than Napa sells it for.
  7. Looks good; especially for the money. But, 15 WPC is a little anemic for most purposes. I’d say that 25 WPC would be adequate though. I think that the best value in tube Chi-Fi is the Yaqin MC-100b. 100 WPC, full dual-mono, about $700.
  8. Of course the MMG and the Point Sevens are better, overall, but neither work very well as desktop speakers, or speakers for small bookshelf systems, which was the point of the review, I suspect. The MMG is, in my opinion, probably the best speakers under $1k that there are, but they require a lot of power as do the Point Sevens. I thought that the MiniMaggies were the worst Maggie’s I’ve heard, especially for the price. But the Motion 4i is 70 - 23,000 +/- 3dB. That’s pretty flat over the speaker’s range.
  9. I have an Otari Studio DAT recorder called a DTR-80 (with balanced AES/EBU ins and outs) and long ago, I transferred all of my analog master tapes to DAT (Had to. I used Ampex Grand Master 456 tape with the “anti-slip” coating on the back of the tape and the binder from this coating turned into goo after a while! I was lucky to be able to play each tape one more time to transfer it by holding Q-tips soaked in isopropyl alcohol against the back of the tape to remove the goo as I shuttled the tape onto a take up reel (tapes are commonly stored “tails-out”) for play.) I then have been able to transfer the DAT tapes to CD using a TASCAM CDRW-900 Studio CD recorder. The DATs are 16/48 but the CD recorder allows for down-converting the S/PDIF to 16/44.1. If you don’t have access to a studio audio CD recorder, Then I suggest that you copy the DATs onto your HDD using Audacity and then write the CD from your computer, letting Audacity convert the DAT format from its native 48 kiloHertz to the Redbook 44.1 kiloHertz. Be advised, that it is possible with some DAT machines to record at 44.1 instead of 48, and whoever made the tapes that you need to convert to CD might have made them at 44.1 and you can just dub them directly. The display on the DAT will tell you the sampling rate so there would be no guessing on your part. Hope this helps.
  10. Well, in my opinion, the question is a lot like asking how does a Honda Civic compare to a wheel chair? They both have four wheels and are used for transportation, but the comparison pretty much ends there. I had the mini Maggie’s in my system when they first came out and was not really impressed. I thought that the planar woofer was pretty much a joke and the main panels, while hey sounded fine, took up too much desk space. Were I to contemplate going that way, I think that I would forego the bass panel and just get the two main panels and pair them with a suitable self powered subwoofer (or two).
  11. Read the Stabilant white paper. It should be on their web-site.
  12. But you said that you had not tried Stabilant!(?!). Stabilant is, by itself, non conducting. Only when used in conjunction with the mating parts does it increase the area of the connecting surfaces. So one can use it without fear of inadvertently shorting out nearby connections by sloppy application. BTW, Stabilant is the goop itself, and Stabilant 22a is the goop diluted with isopropyl alcohol - which is how it’s supposed to be used.
  13. Yes, various liquid unctions are reversible, unlike the soldering of connections which is not. Believe me, the military wouldn’t give Stabilant a Mil-Spec number and the Society of Automobile Engineers (SAE) wouldn’t have given the stuff a spec number and NASA would not have spec’d the material for use in spacecraft, rockets, and satellites. I’d say that this is ample evidence that Stabilant does what it says it does. Also, when Dayton-Wright was selling Stabilant 22a as Tweek, this audiophile treated one channel of his system, the difference, with a mono signal, between the treated and the untreated channels was immediate and profound. It even fixed an intermittent connection in my Alfa Romeo’s speedometer. In short, it works.
  14. Try Stabilant 22a, before ruining your connectors by gooping them up with solder. Stabilant is so good that NASA uses it on connectors as does the entire Aerospace industry and most automotive companies. It ain’t cheap, but unlike soldering one’s connections, Stabilant IS reversible.
  15. No, but my iPad’s autocorrect is definitely a liability sometimes!👿
