| Why so expensive?? We have an amp that costs $92,000... it takes 2 of our guys about 3 months of solid work to build it. Its on 4 chassis and makes a lot of power: 500 watts into 4 ohms and it has built in tube testing and power line regulation. At least when done y... | |
| Open Baffle Phy HP KM 30 SAG update A customer of ours brought in a set of PHY KM 30 SAG 12" speakers, based on a series of reviews he read. One of the reviews recommended that our amps were a good match so he ordered a set of those as well. I have to say the PHYs were quite impress... | |
| Why so expensive?? If I can point out a few things:Anyone who objects to the price might want to do a serious price analysis on what the parts cost, the cost of labor, the cost of certification (such as in the EU), the cost of shipping, the cost of reviewers on the ... | |
| Class-D amps - a different re view Guidocorona, I was merely commenting on a spec that clearly was not possible as it was represented. I also demonstrated that with the math.If you think I was taking a pot shot, I apologize. However, let me point you to a paper:http://www.atma-sphe... | |
| Class "A" s.s. vs. tube amps Class A refers to the operation of the output devices and is neither a tube or transistor thing- its both. Class A makes the most heat and the least amount of power, but is also the lowest distortion. Class A amplifiers can be either single-ended ... | |
| Class-D amps - a different re view Kijanki, not to detract from your comments of the review of the review, but just so you know the numbers that are quoted are not speaker current. If it were:First, reality:For 100w into 8 ohms, the current would be about 3.54 Amps.For 100w into 4 ... | |
| I have just purchased the latest Sound Lab M1 You'll have to sort out which side of that understanding you are on then. So- by you: a transformer is not a transformer and semiconductors are not semiconductors. | |
| I have just purchased the latest Sound Lab M1 So that people can get a little grasp, because it's not output transformer coupled, so then what is it???Why don't you call it what it is? An amplifier coupled by an RF transformer, bypassing traditional output transformer problems? Instead of mak... | |
| Class-D amps - a different re view Kijanki, FWIW your comment:My Icepower being smallest of the series has peak current 11A. Larger 201 has 20A and largest 501 has about 50A.has an ambiguity. The 50A peak current you mention- is that the output? Assuming a 1 ohm load and 50Amps, th... | |
| I have just purchased the latest Sound Lab M1 Hi Allan, there is a product called the ZERO (see zeroimpedance.com). It allows our smaller amplifiers to drive loads down to 2 ohms. Its an outboard output transformer, but one with a very low turns ratio.Without it, our smaller amps can't drive ... | |
| I have just purchased the latest Sound Lab M1 Hi David, your numbers are impressive and as I have always made sure to mention in the past, its an impressive design. I was privy to Harvey Rosenburg's plans when he coined the acronym 'ZOTL' back when he was making a deal with you to manufacture... | |
| I have just purchased the latest Sound Lab M1 Hi Allan, I think there is some confusion- I've never said the Berning was 'digital'-ever...To be an OTL specifically means no transformers at the output of the output tubes. Its a technicality, the point is that calling something that it isn't is... | |
| I have just purchased the latest Sound Lab M1 Oneprof, FWIW while unquestionably a brilliant design, the Berning isn't an OTL- it has both an output transformer and semiconductors in the output section. | |
| Class-D amps - a different re view Kijanki, I agree completely- and will add that many of today's specifications exist to sell certain types of amplifiers rather than get to the truth of the sonics. | |
