There are many models of op-amps. They all have different specifications such slew rate and bandwidth. You have to select the op-amp to fit your amp's design. An op-amp usually does not cost more than few ringgit.

The imageshack crap affects Lowyat.Net as well. It will show up if you have registered an account with imageshack. I have also wrote to imageshack to whitelist my blog URL. Quite disappointed with imageshack this time.

I didn't even buy Fluke although I studied electronics degree. I'm using a RM100 E-Sun meter, with frequency, temperature and capacitance measurement. My advice is, don't buy something as fancy as I got. Spend slightly more on a rock solid pure DMM. If you want to measure inductance/capacitance, do get a LRC meter seperately. Likewise, get thermometer if you want temperature.

It's not bad lah. Still surviving until today, been through my entire degree. Just nothing great to boast about it.

Does it affect if I ate rice for lunch? Maybe stronger effect
 I've seen power cord tuning by laying power cables on pieces of wooden blocks. And these wooden blocks or tuning products, cost a bomb. If think you can feel the difference, be prepared for huge financial expenses. |

QUOTE(Cosef @ Mar 8 2011, 11:24 PM) Resonance, i still on searching the theories of that. I didn't say it's a trolling fact. Lol. I have tried tuning feet and sticker-like (wall tuner?) product. I did feel the difference. While my 'feel' could be a placebo, I'm certainly to say that the product is well marketed to affect the listener's perception.This one you should believe it, no need to get the products, those are making business, a tissue roll or anything that can space up will do. You should try it on interconnect and speaker cable, easier to hear the difference. At 1st i was thought it was a troll like you, laugh at those audiophiles on maximum placebo, until i found out myself, i took back my words.  |
