| Do I esentially have a class A amp? NFB lowers output impedance. If amp has 10x higher gain before applying of NFB then feedback will lower output impedance tenfold. We call it 20dB feedback. As a result deep NFB some amplifiers end up with output impedance of single milliohms. Ther... | |
| Do I esentially have a class A amp? Runnin, 250W would be nice if you can get it for the same price as 100W but if it is more money than perhaps getting better 100W (better design, better components) would bring more satisfying sound.Bifwynne, Local feedbacks are better. Even emitte... | |
| Do I esentially have a class A amp? 35W won't tear the walls but don't forget that 350W (that tears the wall) is only 2x louder. Also 3dB more sensitive speakers will give you same as doubling the amp power. So, how your 35W amp compares with good 140W amp driving 3dB less efficient... | |
| Do I esentially have a class A amp? Digepix, I understand that you consider class A better sounding, otherwise you wouldn't care. It should be better sounding if it is designed that way. Class AB has to use more of negative feedback to counteract nonlinear operation of output transi... | |
| Want to replace my speaker cables I use Acoustic Zen Satori. I considered Analysis Plus Oval 9 but few people found it bass heavy. Satori is very good and not that expensive. I bought it for my class D amp to add a little weight/fullness to lower midrange but was very surprised ho... | |
| CD Tweeks...Improve Ripped SQ? I disagree completely as well. CDP cannot, playing in real time, reread sector with wrong checksum. When it happens it corrects errors on small scratches (roughly up to 4mm along), interpolates data for medium scratches (4-8mm) and loses data (pop... | |
| Help on Power conditioner Rabbani, it sounds like you have undervoltage problem. It should not destroy anything. If it doesn't affect the sound leave it alone. Still, voltage spike caused by lightning or nearby inductive loads (like motors) switching is always possible. I ... | |
| Help on Power conditioner All equipment designed to placed on European market since 1995 has to operate at 230V +/-10%. 180-190V is low but it should not damage anything. Why would you like to control fluctuations? Does it affect the sound? | |
| Are unequal length speaker cables really bad? Some people believe that there is nothing better for speaker cable than lamp cord, but if you believe that speaker cables affects the sound then sound change should be proportional to length of the cable. 1/4" would not make any difference, I'm su... | |
| Cause of different sound between dacs 1. Jitter2. Digital signal processing3. Analog circuitry (including power supply). | |
| How to protect turntable from children? MKsolid, Don't listen to Dekay. Locking children in bookcase is cruel and inhumane. Buy pair of handcuffs instead - it works really well. Seriously, the best way is to explain it to children. I showed my 3 year old daughter how to operate tape dec... | |
| What does capacitor endurance mean? This rating is at 105degC. Assuming your capacitor runs at slightly elevated temperature of 45degC it will last over 50 years (since life of capacitor doubles for every 10deg C temperature drop). At this time electrolyte will simply dry out causin... | |
| If you were setting up a music server today ... As I said before increasing amount of RAM or caching music to RAM is useless with Wi-Fi. It is because computer doesn't transfer music at all, but instead transfers data compressed in packets. Data does not have timing. Timing is recreated on the ... | |
| If you were setting up a music server today ... Wireless has many advantages. It keeps noisy computer electrically isolated and physically far from audio system. It also makes other factors like type of computer or playback program irrelevant. Instead of spending money on fast computers, a lot ... | |
| Basic Foobar Question Why to use Foobar? You send data to your AE in packets. Data has no timing (recreated by AE). Nothing on your computer side make difference (unless program does data processing - like upsampling).Standard AE has decent digital output (258ps jitter... |
