| Class D amps,bang for your buck ones PS Audio GCC series uses ASP ICE modules. Available in 3 ratings and use the PS 'Gain Cell' input. These are integrates.PS also made basic amps without pre section. My Maggies seem to be enjoying themselves with the GCC250, which doubles up at 4oh... | |
| Amplifer Wattage Question How about electrically?Use a DVM and if speaker impedance is known at frequency, use test tones measure the voltage and using ohms law and the impedance, calculate the actual wattage?Will this work? It actually doesn't sound like THAT much trouble... | |
| "Ever happen to you" strange electronics Stuck Relay?Does the Krell even HAVE a relay?I drove the neighbors NUTS for a month with an RF remote control set to the same code as theres! Big Fun. I'd step out to the kitchen, aim towards the back windows and see the glow of the TV flicker as ... | |
| SET with inefficient speakers Sonic,One of the biggest myths in audio is the impedance myth. Tube guys will talk about various tube till dawn, spouting opinions about what does or doesn't sound better, but audiophiles of all stripe typically ignore some of the measurables whic... | |
| NAD vs. Adcom I'd guess the bi-amping with such dissimilar amps may be the 'problem'.Almost any single more powerful amp will help. A good integrated which can handle the B&W load, not just impedance but phase angle as well, is recommended.Maybe a NAD in th... | |
| $8oo dollar budget Based on the Stereophile measurments of the original test, I'm kind of surprised you get good results with the matchup to B&W.www.stereophile.com/solidpoweramps/675/index9.htmlThey had some... difficulty... at 4 ohms, not to mention lower.Also... | |
| Suckout at 40 hertz...less pricey solutions? How wide is the notch? (in octaves or freq)Google 'room mode calculator and enter your base dimensions. This could give you an idea of the resonant modes of the l/w of your room. The vaulted ceiling is tougher to figure. | |
| Power conditioners Power problem effecting only left side? I don't buy it.Something else, cable, upstream component, haunting..... is to blame. | |
| Amplifier Power Ratings & Speaker Sensitivity Un:Also FWIW, it seems that people rely on 'cheap watts' to make up for some pretty wild speaker designs. Also, most opin that it is impedance (low) which makes for a bad speaker load.That is simply not true. Even an 8ohm near-resistive speaker (i... | |
| Ohms, my - help me understand I just looked up the 'road test' of the CS2 and indeed, the impedance is a fairly mellow line. NO phase data provided, but the test remarks opin'd that they are indeed a fairly easy load. Again, however, when dealing with speakers at this level, b... | |
| Amplifier Power Ratings & Speaker Sensitivity Only 1 fly in the ointment.If you need say .... 100 watts to produce the desired SPL, there is another factor to consider.IF the speaker presents a bad load to the amp, in the sense of large phase angle, you can cut in to available power badly. If... | |
| Subs for Lower x-over = better.I use a HSU, ported sub and set it up at about 40->45hz. I experimented for a couple weeks after getting the sub, going to lower and lower x-over, while adjusting the gain and phase. Maybe I didn't go low enough in the x-o... | |
| amateur needs amp advice for a 2.0 setup - please Consider running / maint. costs of tube.An integrated w/tube pre / SS output may work and have lower operating expense. You might also be better served with decent entry level SS amp, of good reliability and resale while saving for a pricier tube ... | |
| How much Watts for a 20 x 20x 9 Foot Room How loud to you like it?How sensitive are your speakers?HSU Research site, I'll post link if you need it, has a room size calculator.Your room is 3600ft/cubed which isn't all that bad. The REAL bad news is that it is a perfect square which is just... | |
| Why do speakers recommend amp wattage? Instant current delivery is of some importance. Continuous? quite a bit less, since SS amps are typically voltage source amps. Even my panels, which are considered 'current hogs' by all, have only a 4 amp fuse on the mid/hi driver. Even if the LF ... |
