| Does the volume control effect sound quality? I believe that the volume potentiometer (pot) is the single most important component that can have detrmental effect on sound quality, this is why they all sound different to each other. All volume controls have pin point touch contact that are pu... | |
| Short Run .5M Interconnect on a budget? Hi Dhcod, the Lightspeed Attenuator likes to see interconnects to the power amp with capacitance of less that 100pf (picofarad) per foot The .5mt should not be a problem with any good quality interconnect, the sounds of which are personal and syst... | |
| Sonic differences on High-gain vs Low-gain Amp It depends on how the gain is changed, if it is increased by reducing the feedback or reduced by increasing the feedback, then yes there will be a change in sound quality. To what the differences are, are up to how good/bad the amp behaves (techni... | |
| PreAmp Gain and Impact on Amp I also wanted to add but forgot, there is the same amount of dynamic headroom at half level as at full level on what I've said in the above post. Cheers George | |
| PreAmp Gain and Impact on Amp If full up on your preamp is loud enough for you, it will not sound any better with more gain on the same preamp and only half up for the same volume as full up with less gain.Cheers George | |
| Preamp - 18 dB Gain too low? Jeez, what a s**t fight this has turned out to be, most any active preamp is going to have trouble with this as you have found out with your Conrad Johnson PV-10AL and all passive preamps as well. To make the input of a power amp 4v sensitivity is... | |
| Preamp - 18 dB Gain too low? More on the Oppo's stereo only output, are you getting the siganl from the FL and FR outputs on the back to the Lightspeed?Also taken from the manual are you setup it the programing for this way."4. Output Volume: Allows you to enable or disable t... | |
| Preamp - 18 dB Gain too low? Another thought, your Oppo cdp has a remote volume control, is it at full output level? As it may default to 1v or less when powered up and you need to bring it up on the remote to full 2v output.Cheers George | |
| Preamp - 18 dB Gain too low? Nguyen787Here is a way out there thought on your problem. You say your running the amp on 115v mains? It is possible that this amp/s are set up for 220-240v mains operation, this could? drop your gain/input sensitivity.Cheers George | |
| Preamp - 18 dB Gain too low? An input sensitivity for an amp of 1v is quite normal as nearly every amp I've seen on the market has been .5v to 2v for max rated rated output (to clip/distort). An input sensitivity of 4v is wrong/bad and I would call the amp broken or seriously... | |
| Preamp - 18 dB Gain too low? Still no good here it is again.Nguyen hi, just looking at the factory specs for your 845 amps they are very sensitive at less than 1v for full output. There is something not right with your system as Red Book standard for cdp is 2v out and most ar... | |
| Preamp - 18 dB Gain too low? Sorry a line was left out above Nguyen hi, just looking at the factory specs for your 845 amps they are very sensitive at Cheers George | |
| Preamp - 18 dB Gain too low? Nguyen hi, just looking at the factory specs for your 845 amps they are very sensitive at There is something not right with your system as Red Book standard for cdp is 2v out and most are higher than this so your Lightspeed should be below half wa... | |
| Preamp - 18 dB Gain too low? Nguyen787. A very good quote from god! Cheers George"Nelson Pass, We’ve got lots of gain in our electronics. More gain than some of us need or want. At least 10 db more.Think of it this way: If you are running your volume control down around 9 o’c... | |
| no volume control Sugar1, what a Lightspeed will do is give what your source (cdp, dac, etc) is giving out without anything added or subtracted, in other words it's like feeding your source directly into your poweramp, yet with control over the volume. It's like an... |
