| Looking for 200 watt Amp to drive Dynaudio Heritage speakers So I decided to give the Dynaudio HS speakers a whirl with the Conrad Johnson amp which is 125 watts per channel. I didn't expect much, but was sort of blown away. The CJ amp totally opened up the speakers in a way I didn't expect and made me rea... | |
| Subwoofer xLr connection According to the manual, the 1000X assumes that line level and XLR inputs are going to come from the LFE output of a home theater processor and the internal crossover is bypassed. So some form of external bass management IS required if using this... | |
| Amp, Preamp, two volume pots, there can be only one! in theory which specs would the amp need to have to play along with my preamp? @neverlast Find one that takes 2Volts or more for full output. If the amp is properly designed, that will drop your noise floor about 15 dB and will make your volum... | |
| Subwoofer xLr connection @alanpiga If you are using a powered sub it has all the bass management you need, which is why preamps don't have it. | |
| Who out there wants to, or has, validated an amazing cable find? I did mention the insulation on the Mogami is PE and the jacket is PVC. @jim2 Sorry- somehow I missed that. Thanks for the blast from the past about feedback. The reason zero feedback is used is to prevent distortion rising with frequency. But ... | |
| Class D Amplifier(s) for SWARM Subwoofer System @peter_s As I mentioned before, if one of your cables is wired out of phase with the other then the sub amp will only play out of phase bass information. IOW it would sound weak. So check your interconnect cables to see if they are both wired corr... | |
| Amp, Preamp, two volume pots, there can be only one! @neverlast With full output at only 300mV your amplifier is far too sensitive. Since it can only make 8 Watts, it has to be used on a high efficiency speaker. So you'll be fighting noise. So yes, that's a bit of a mismatch! Usually SETs (or SEP i... | |
| Who out there wants to, or has, validated an amazing cable find? advice to try Mogami for XLR... and that any quality wire in an XLR implementation is going to get the job done. I’ve been using Mogami 2549 (22awg) for XLR into my Ayre VX-5 Twenty. @jim2 Just for the record that wasn't exactly my advice. My a... | |
| Class D Amplifier(s) for SWARM Subwoofer System Jensen ISO-MAX PC-2XR, which converts the balanced to SE signal (and +4 to -10 db conversion). I am guessing that Ralph is doing the same, but require confirmation. @peter_s I run the same configuration and it works fine. You might test your bala... | |
| What's the benefit of balanced tonearm cables? zombie thread come to eat your brains! | |
| Does a turntable mat make any difference? What else can put 220 class A watts into 20 ohms @mijostyn Sound Labs actually get to 30 Ohms in the bass. That's why solid state amps have a hard time driving them. | |
| Western Electric 300 B Vacuum tubes @moose89 I’ve been doing this stuff for over 45 years. That’s a new one on me. FWIW, usually anything other than the filament being lit and a light blue glow just on the inside of the glass when running, any ’lights’ or other phenomena inside a t... | |
| Good Speakers for Rock and Roll Under 15K Can you measure dynamics and punch of a speaker? @mofojo Yes. There is something called ’thermal compression’ that has to do with the voice coil heating with bass notes and the like. When the voice coil heats, its harder for the amp to put cu... | |
| Is more amp power always better...? @dunkin The most important thing is that the amp have good clean reproduction at a low power level like 1 Watt because even with your speakers that will be a common power level. The class of operation, the amount of power isn't important as long ... | |
| Western Electric 300 B Vacuum tubes @moose89 What color is the 'vapor' (BTW its not actually a vapor but it is caused by molecules in the tube)? If bluish, no concern. |
