| Lightspeed Attenuator - Best Preamp Ever? 03-03-14: 4hannonsDrubin, I wouldn't use the Pardo;the 12V/2A will fry it. The LSA takes 1A max I beleive. I'm not an expert, maybe others with more knowledge will chime in here...Sorry but just to correct this, it will work fine, so long as the p... | |
| Lightspeed Attenuator - Best Preamp Ever? Hi, Audiolabyrinth, tell him to come over here and read this.I had a quick read of that thread, and there are those that like to be on the preamp merry-go-round, spending lots of money and are addicted to it. They say that their preamps aren't col... | |
| Pass Labs amps and Avantgarde speakers Mohano hi:You have the bass of the Duo's sorted as they have their own 250w amp correct? So all you need to drive is the mids and tweeters at over 105db effecient with a very easy load I believe over 10ohms, and easy low -phase angle. So the ideal... | |
| Parasound HCA-2200II Runs Very Hot Morgandogge hi: The B&W 802's are bit of a pig of a load to drive, so yes your amp will be working hard, pumping out good amounts of current. So long as both sides are the same temp, all should be ok. The Nelson Pass test, 30c-35c ambient temp... | |
| The best preamp for Rouge M-180 Nr9 hi, If you you can use low capacitance rca interconnects (which most good ones are) the Rogue M120 and the M180 are perfect to be used with passive preamps. As they have very high input impedance (at 1 meg ohm), so there's no need for active o... | |
| Pre-amp or cd direct to XA30.5 ? FsymeI would set it .5v first and if you can get loud enough volume, then your your fine. I'm sure you will as that's around 2/3rds of the XA-30.5's full output. If not then go to 1.1vCheers George | |
| Pre-amp or cd direct to XA30.5 ? I had Mark Levinson No.39 a while back same setup, that's why Wadia did this also, so you could run it near full digital volume with the analogue gain selection so there was no risk of "bit Striping". But to be honest the difference between full 1... | |
| Lightspeed Attenuator - Best Preamp Ever? Found it and answered.http://forum.audiogon.com/cgi-bin/fr.pl?aamps&1392847679&&&/Pre-amp-or-cd-direct-to-XA30-5-Cheers George | |
| Pre-amp or cd direct to XA30.5 ? I think there is an ulterior motive for saying this, a standard Oppo 105 that has low output impedance would be fine driving into the XA30.5, but Oppo 105 with a modded tube output stage will be much higher in output impedance, and maybe have trou... | |
| Pre-amp or cd direct to XA30.5 ? Your Pass XA30.5 has 30kohm input impedance, this is fine for you to direct connect from a source that has a digital domain volume control.Just remember that some digital volume controls can "bit strip" if used below 2/3rds of full output.Bit stri... | |
| Lightspeed Attenuator - Best Preamp Ever? Audiolabyrinth, I tried, but couldn't find the thread, which forum is it in?Cheers George | |
| Bypassing A Preamp With Volume Pot In Amp Correct Jetrexpro, nearly all sources these days have output voltages higher than what the maximum input voltage is needed to drive amps into full output. So there is no need for preamps with gain. And if you have a source with low output impedanc... | |
| Bypassing A Preamp With Volume Pot In Amp Lse, it's not a pot (potentiometer). It's just like a direct connection between source and power-amp with none of the contacts or preamps active components in the signal path, like a pots very lightweight wiper contact or switched resistor pots co... | |
| Bypassing A Preamp With Volume Pot In Amp C_avila1You haven't mentioned the input impedance of your poweramp.I say 10K as a general even when direct connected, as most amps are 47kohms (industry standard) input impedance. If you have say a Rogue tube poweramp which are 1mohm input impedan... | |
| Bypassing A Preamp With Volume Pot In Amp You'll find a lot of so called intergrated amps these days are exactly just that, a power amp with a passive and input switching, many of these are coming from EU and Asia and some are "Hi-End" tube mostly but now some solid state as well.Cheers G... |
