| Direct Drive vs. Idler Drive vs. Belt drive This is not just me but but all the audio big wigs in Miami circa 1980. The drive behind these tables was that they were cheaper, easier to assemble, much lighter (less expensive to ship) and could be pumped out in large numbers which they were... | |
| Short List of Amps I prefer over the Pass Labs XA25 or INT 25 Then you need a good DSP unit I guess. The DSP is built-in to such amps that have a direct digital input. Conrad Johnson preamplifiers have notably high thd I saw in specs of all the recent models et6 et7 and gat it is 0.15 (I was surprised to s... | |
| Bias adjustment on solid state amplifiers Just get a Digital Voltmeter with a current scale. Most have a scale with a range of milli-amps and also up to 2 amps and work fine for that. | |
| Direct Drive vs. Idler Drive vs. Belt drive The problem with Direct Drives is a big oscillating magnetic device directly under a very sensitive magnetic device. @mijostyn What is the result of this? We've been making and playing belt drive machines for about 20 years but when playing the ... | |
| Break in time that extends to months or maybe even years!! according to the member who is reviewing it, needs in excess of 1000 hours to fully break in!!That's actually long enough that if a tube unit, it might have had to have tubes replaced already (although that would be a short period for a tube). Th... | |
| Advice on replacement of Stereo-70 (for Cain& Cain Abbys) What is the failure with the ST-70?? The power transformer? If no, its probably cheaper to fix it than move on, unless it wasn't doing the job for you. | |
| Break in time that extends to months or maybe even years!! I'm really doubting that much break-in time is needed; the product could never get traction! | |
| The bass is the place... Getting bass right means you need to have the bass emanate (in most rooms) from several locations at once. This is because most rooms have standing waves forming at bass frequencies, and no amount of power to correct a resulting deficiency at a ce... | |
| Demo'ing Class A amps, Appreciation Suggestions from those who recently been there You can PM me or call me, since we are considered 'critical industry' by Minnesota. atma-sphere.com | |
| Suggestions for good cheap Equalizer Good, cheap and equalizer all in the same sentence. Choose one from column A and one from column B. You don't get all three at the same time.Brightness can be the result of distortion- this is why solid state sounds bright. Its not much at all, bu... | |
| Demo'ing Class A amps, Appreciation Suggestions from those who recently been there What about the XA25I can't tell from stuff online. A call to Pass would sort that out though. | |
| Efficient, affordable speakers for SETs? I had some experience with PHY drivers. The Ocellia speaker uses them and is very sensitive but not dynamic enough. Audio Note UK are an industry standard for decades but their output is also somewhat limited. The Ocellia and AN seem good for c... | |
| Short List of Amps I prefer over the Pass Labs XA25 or INT 25 Eric, i thought feedback was something to create the gain. I am too far from this field, but will try to have a look on some books (e.g. why the feedback is unavoidable). Could something similar to switching waveform be used to create a correc... | |
| Demo'ing Class A amps, Appreciation Suggestions from those who recently been there Atmo- I read your comments about a tweeter's Unbearable Harshness of SS and hope you are somehow unaware of a cure. Cables?@chorus I suspect you have a typo here.The brightness is caused by distortion and because its in the amp, probably not somet... | |
| what's the point? According to this, all amps that are played below clipping sound the same (indiscernible).Obviously the statement is false.It presumes that all amps have the same amount of feedback (they don't) and further that the feedback renders them a perfect... |
