| Voltmeter for Vandersteen 5a setup They most likely want to apply low frequency 1V sinewave signal (100Hz -1kHz) and measure/set -3dB point. Any voltmeter will do (no need for true RMS). One recommended by Czarivey is pretty good one. I have cheaper, non-RMS version for more almo... | |
| Can SMPS based preamps/amps sound organic ? Patent does not mean much (I have couple of them). Patenting new principle of operation is practically impossible, so the most of people patent specific use. You can come up with any weird stuff and register it. Patent office does not check val... | |
| Can SMPS based preamps/amps sound organic ? Bombaywalla, I'm familiar with class G principle of operation. And you're right - their "invention" is pretty much class G. It does not matter if you switch signal or supplies - it is still switching operation. Rowland (IMHO) is the leader again... | |
| ASSEMBLED IN CHINA chrshanl37I'm glad you mentioned McDonalds. The wage they pay puts people below poverty level and I pay their supplemental income (gov. support) instead of McDonalds.You are right about some audio stores going bankrupt initially, but later buying ... | |
| Can SMPS based preamps/amps sound organic ? Bombaywalla, Thank you for the link, very interesting. The only problem is that what they describe:The digital control circuitry constantly monitors the pulsating waves from the regulator and the rail voltages. It will then make a decision to tu... | |
| Can SMPS based preamps/amps sound organic ? Jaybe, I repeat again - most of linear power supplies in power amps are unregulated. I would bet that 100% of linear power supplies in class A amps are unregulated. Can you provide the link? Sonore, you mentioned are 14W, unless I'm looking at... | |
| ASSEMBLED IN CHINA Tim Cook of Apple stated that we lost our manufacturing ability long time ago:“The U.S., over time, began to stop having as many vocational kind of skills,” Cook explained. “I mean, you can take every tool and die maker in the United States and pr... | |
| Can SMPS based preamps/amps sound organic ? But I can think of a reason a LPS may sound better in your home. One thing is a transformer will filter out or reduce incoming high frequency electrical noise where especially older SMPS will pass it through. Modern SMPS often contain Power Facto... | |
| Relationship of amplifier sound to transformer quality? If the transformer is not wrapped with low frequency high permeability mu metal sound quality will suffer. No two ways about it. The toxic effects of the induced magnetic field extends to everything within what, about a foot of the transformer? ... | |
| Can SMPS based preamps/amps sound organic ? Why to design complicated SMPS when the most of customers believe that it has to be big and heavy to sound good? Small and efficient bring suspicion that something (sound) has to give. In addition word "switching" suggests electrical noise. | |
| Can SMPS based preamps/amps sound organic ? Jeff Rowland uses SMPS for low noise. That’s why he uses them in applications where efficiency is non-issue, like Capri preamp. SMPS got bad rap from crude computer applications but when is done right is extremely quiet. Most of linear power suppl... | |
| Acoustic Zen +1 Sherod, I missed it. Mine is Absolute. | |
| Whats a good all around digital cable for under $250. I only need half a meter. Get >1.5m or <1ft (I can explain why). It applies only to coax. It is a system thing - a cable that sounds great in one system might sound bad in another (characteristic impedance mismatch and/or electrical noise induced jitter). Cable ... | |
| Audio Show - Best Sound comments So, I think, you definitely get what you hear... but the price tag will influence you more... and most think, getting a good price for something will increase its - non-existing - "qualities" When you audition the gear you try to find shortcomi... | |
| End of the line products. Hyperion Sound HPS-938 speakers. There are a lot of better speakers, I'm sure, but Hyperions midrange is to die for. They are also warm sounding with perfectly integrated tweeter. Unfortunately company went out of business for the lack of marke... |
