| Best Preamp = No Preamp? Most SS sources (excluding tube ones) have an output stages that can equal and sometimes better many preamp output stages, especially tube ones. So the myth that a preamp can drive the interconnects to the amp better is a "furphy", and started by ... | |
| Lightspeed Attenuator - Best Preamp Ever? I don't know, but if you look at the thread I posted at diyAudio forums on how to make a Lightspeed yourself if you electronically minded. http://www.diyaudio.com/forums/analog-line-level/80194-lightspeed-attenuator-new-passive-preamp.htmlIt's ra... | |
| Lightspeed Attenuator - Best Preamp Ever? Very well put Lacee. Just two words sum it up "BLACKER BACKGROUND" This not only improves dynamic range as it lowers the perceived noise floor, but gives you space between notes, as well as transparency to the sound.Cheers George | |
| Why do some audiophiles beat up McIntosh? As not many would understand Pops.Source: My own heavily modded CDP switchable input receiver from PM200 HDCD chip to DF1704PCM1704K (selected) 24bit R2R ladder Multibit dacs.Very special zero feed back direct coupled active I/V stage, and pure cl... | |
| Lightspeed Attenuator - Best Preamp Ever? Like a metal dome tweeter without a Zobel network on it, they ring very similar and sound "hot". And the proper word to call it is it's resonance frequency, "ring like a bell" is just slang. That is why when the TVC is loaded down by a 1kohm load ... | |
| Why do some audiophiles beat up McIntosh? Hey Sid42: Careful, you've been known to bash the transformer coupled ones as well. These are the only ones I and others believe need to be "bashed".Quote Sid42 "7200 was/is the best amp they've made, and with no autoformers.. In my experience, al... | |
| Lightspeed Attenuator - Best Preamp Ever? Hwv1 hi. Thank you very much for your praise and very in depth review. And I'm not surprised it better your TVC preamp, as Shakeydeal also has said, as transformer (TVC/AVC) preamps have a problem as I've outlined to Milpai above.Yes with any pass... | |
| Is dedicated PreAmp with Oppo 105 needed? Hitsofmisses hi.Your Oppo has a digital domain volume control, are you using it's 5 channels direct into your Parasound Halo A51, and the sub output into your sub? As this is the way I would use it, so long as the digital volume control is at or a... | |
| Lightspeed Attenuator - Best Preamp Ever? The rising peak into the high frequencies in the first graph I last posted. If this was to be seen as a square 10khz wave response on a scope, the top of the square wave would be ringing similar to this 1st link, instead of being perfectly square... | |
| Pre-amp recommendation Be careful with your choice of preamp as it has to drive both the SA1 (75kohm) and in parallel whatever the input impedance is of the Galo sub is. I cannot find this anywhere. If it (the Galo amp) is 10khom to 50kohm this can present a combined im... | |
| Lightspeed Attenuator - Best Preamp Ever? Hi Shakydeal, Sonic Euphoria looks to be out of business.I can understand why you like LDR passives, this is the problem with TVC/AVC passives, look at the frequency response of it into 100kohm 10kohm 5kohm input impedance of poweramps. It rings l... | |
| Audio Research and Martin Logan Montis All I can say to that is, "why do all equipment manufactures strive for a flat response?" And give +-db frequency response measurements points in their specifications?If they wanted to have it altered all over the audio spectrum because of externa... | |
| Audio Research and Martin Logan Montis 03-06-15: Zd542What difference does it make if the system sounds OK? What about a different speaker like the Prodigy? Would you say the same about that one?Well your not listening to a flat frequency response, it like having a fix tone control emb... | |
| Audio Research and Martin Logan Montis Zd542 This is the kind of non linear frequency response that may happen with a tube amp at 4.5khz with the Montis, -2db!!! because of it's -55 degree phase shift and combined 3ohms load, because the amp can't deliver current. It has nothing to do ... | |
| Audio Research and Martin Logan Montis Bfin3It may sound very good with your 80w tube.But with this statement for the measured Stereophile tests, it maybe not at it's "best" with tubes. "Stereophile: Either way, that this speaker is a difficult load for the partnering amplifier to driv... |
