| Class D Technology I’ve seen it on the scope, with Nuforce 9se V3, you need to see it for yourself. Lower or raise the signal level at the same frequency, then increase or decrease the scopes sensitivity to the same visual appearance, and you’ll see the SF noise rem... | |
| Class D Technology Sorry your wrong kijanki, the switching frequency to signal ratio follows the signal level in a proportional manner. and that 20% pod SF noise in the links I provided above, the SF noise does not disappear at certain levels of playing, it stays pr... | |
| Class D Technology There is about 1% of switching voltage noise on the speaker cableYou need to rethink this.Look at the switching noise ringing on the test square waves Stereophile show when they don’t use their special Audio Precision’s auxiliary AUX-0025 passive ... | |
| Class D Technology I read a tip that a portable am/fm radio could be used as a crude detector for any RF radiation emitted by a component.Yes for smps leakage, should also work not that I tied it for Class-D switching frequency leakage.Tune down low and try at diff... | |
| Class D Technology NCore1200, not on the lower end NC500 module... My bad!!!!The NC500 is their newest most advanced module not mentioned anywhere on their site, avalible only to selected few, and is in the BelCanto Ref 600 monos, but BelCanto used their own filters... | |
| What should be removed The impedance drops down to around 3 ohms over the 200Hz–1kHz region. A good deal of the power in typical program material falls in this range, which suggests that the CUB will not be particularly easy to drive.http://www.stereophile.com/images/ar... | |
| Wadia 850 repair? Suggested replacement? Your Wadia is a great PCM1702 Multibit player, and has this laser, easy and cheap to replace.http://www.ebay.com.au/sch/i.html?_from=R40&_trksid=p2050601.m570.l1313.TR0.TRC0.H0.TRS0&_nkw=KSS-240A&_sacat=0 The transport mech (Teac) had ... | |
| Using Pre-out / Main-in with External Crossover 64 posts12-13-2016 10:25amThanks George. What about this comment that I read on an old thread. BTW pre-out main-in is not a good place to hook up an EQ from a S/N perspective. The amplifier applies constant gain to any signal at the main-in connec... | |
| Cary CAD 120S Mk II amps Cary CAD 572 SE (20 watts into 8Ω) driving a pair of KEF LS50s. I really enjoy the "warmth" of the sound except for a bit of bass heaviness. Not really the right amp for these speakers.http://www.stereophile.com/images/1212KEF50fig1.jpg http://ww... | |
| Class D Technology Theta Prometheus... I believe it is an NCore NC500Ncore NC1200 class-D module with a linear power supply created by Theta's David Reich.Cheers George | |
| Audio Research Reference 150 and Sonus Faber Cremona fundsgonAudio Research Reference 150 and Sonus Faber CremonaThe SF Cremona need current, and a good amount of it if you want to hear the bass "at it’s best".

| Know of a "Dirt Cheap" tweak? Good tweak if you can still get them or you can make them.http://www.museumwaalsdorp.nl/images/goerz.gif Cheers George | |
| Class D Technology modules and device designs have evolved enormously in the land of class D amplificationI say more of a gradual upwards evolvement, with tweaks and band aid filtering, no real technical breakthroughs. The only one I know who is stretching out for r... | |
| Class D Technology no human has ever claimed to hear these affects or even describe what these affects would sound like.Plenty have with saying, hard sound, soft sound, lacking in harmonic structure, dead gaps between notes (no harmonics) like the amp has been turne... | |
| Class D Technology Noise needs to be heard to existNot correct, EG: take an opamp for instance, it can oscillate (if not implemented well) at VHF, too high to hear, but it will make a known opamp with smooth sound, sound hard/bright because of the oscillation that ... |
