  1. It's REALLY difficult to answer that question, without knowing the following: * Where is the chassis manufactured? * Where are the PCBs manufactured? * Where is the unit assembled? * What quantity is sold over the life of the product? The answers to these questions can make huge differences to the final build cost of a product.
  2. I guess that is a question you need to ask the shareholders. As I intimated, I suspect that building high end amps was not as profitable as doing something else.
  3. I don't believe Halcro ever 'failed'. This short history seems to suggest a lack of interest from the company that purchased Halcro: Seems to be normal. The same thing happened to NEAR and Apogee. The products were excellent, but the profits that can be made from the hi fi business are too tiny for large companies to bother with.
  4. At the risk of dragging this thread WAY off-topic, the VE and VF Commodores are vastly superior to the VT and every bit competitive with BMW and Merc. Nissan, Honda, BMW, Porsche and others had sophisticated, all alloy, variable valve timing engines by the early 1990s. It took GMH MUCH longer to release the technology in Australia. For no good reason that I can see.
  5. Agreed, but COTY has never been about price (within reason). In any case, Merc and BMW (M-series, in fact) have taken out the award several times. I suggest that both BMW and Merc were building better, more sophisticated cars, back when the VT was released.
  6. Primitive engine, way too big and vastly inferior to (say) a BMW 5 series wagon, or a Merc E-Class Wagon of the time.
  7. It does. I never mentioned ME750.
  8. That's OK. Some people only like old ME amps. I'll let you into a little secret: The design has not changed since 1977. Shhh. Don't tell anyone. People always want new and different. They don't want the same. That said, the superior cooling system in the later models does confer reliability and small sonic benefits. You should listen to an ME150 sometime. I have one here you can borrow (you would need pry it from my cold, dead hands, if you ever thought you could buy it). It will alter your perceptions of old ME amps.
  9. Nope. Japanese MOSFET.
  10. The auto industry? In Australia? Surely you jest. Let's discuss: Whilst there are some, undeniably decent, cars in that list, there are a few that stand out, such as: 1978 - VB COmmodore 1982 - JB Camira 1983 - Mazda 626 - Telstar 1985 - TM Magna 1988 - VN Commodore 1996 - TE Magna 1997 - VT Commodore There's probably plenty of others that don't deserve to be on the list either. Most awards (hi fi and car) are a joke.
  11. No problem at all, provided it fits. BTW: VERY unusual to see a WIMA cap fail like this, provided it is used within it's ratings. Are the Chinese counterfeiting caps now?
  12. Yep. I recall Aussie Hi Fi tested a very popular amp available in the late 1980s - early 1990s. It was something like 120 Watts @ 8 Ohms, 105 Watts @ 4 Ohms and 60 Watts @ 2 Ohms.
  13. No, it does not. It shows that the amplifier is either severely current limiting at just below 4 Ohms, or the power supply is limited in it's ability to supply the current required. Either way, the amp should not be used with 2 Ohm loads. This is an example of how an amp should perform at successively lower impedances: 8 Ohms - 91.7 Watts 4 Ohms - 160 Watts 2 Ohms - 235 Watts Note the very healthy increases in power, with successively lower impedances. It MAY do so, but that would depend on many factors, that are not supported by the measured data. IF, for instance, the limited current available at impedances of less than 4 Ohms are due to power supply issues, then the effect will not be too horrible. If, OTOH, the limited current is caused by internal current limiters, then the sonic result may be most unpleasant.
  14. The ONLY reason a manufacturer fails to publish ANYTHING about his/her product, is because that information is not flattering to the product. I hate to tell you this, but if a manufacturer doesn't reveal the 2 Ohm performance capability of their amplifier, then the figure is either unimpressive, or the amp simply cannot deliver.
  15. I can only speak from direct, personal experience.
