| Review: Tube Research Labs Dude Tube preamp No offense to Paul in fact I respect him a lot but the only place shuguangs ought to be found is the dumpster. The chinese just can't help repackaging the same junk in bottles of exotic shapes and colors. | |
| sibilence....any cures out there? Replace the capacitor to the tweeter with some vintage paperIn oil ones. | |
| Cary 300sei driving Wilson Watt Puppy 7 Clipping SE tube amps will not damage speakers like clipping solid state amps. | |
| My system is too loud The gain of the modified Jolida (if thats what your response audio 60W is) is extremely extremely high.You can add a potential divider to the input to attenuate it at the expense of transparency.Ask Response Audio for advice on triode mode which l... | |
| Audio Research Reference Linestages Ref 1 is a an all tube 6922 based preamp.Ref 2 is still all 6922 but with 6550C regulatorRef 2 II is a hybrid with JFet input and 6H30.Chassis may look similar but they are completely different animals.I concur with Sutt's opinion. | |
| Mosfet mist? I personally like the more tube like sonic signature of mosfets vs bipolars. I recently acquired a Counterpoint SA100 rebuilt by Greenstreet Audio with Exicon mosfets and with some tweaking and replacing of the coupling caps @ the tube gain stage ... | |
| Wilson Wat Puppy 7 or Avalon Opus Ceramique? The Wilson is easier to drive and the tweeters are more polite than the Opus Ceramique's. That's based on my experience having owned Eidolons for 11+ years and listened to both Opus Ceramique and Wilson WP7s. WP7s do not sound like WP5s and WP6s. ... | |

| Quad ESL Cap mods Sadly I could not find any photos of the inside showing how I mounted the cap. I remember I took a bunch of them but I could not find them anywhere now. Mine were sold in Sept.Take a picture of yours and I can guide you on how to easily mount them. | |
| Quad ESL Cap mods YOu can still use several AXON 250 90uF available for cheap @ Partsconnexion if you dont want a single cap.SPend some $$$ on resistors, the cap does a lot but its not the be all end all to the mod.Placing them outside the box may involve drilling ... | |
| Wilson Audio Question compaired to Vandersteen I concur with AudioFreakGeek 100% based on my auditions @ various Wilson dealers and owners rigs.Also an audition of a pair of Vandersteen 5As at an in-home audio salon leaves me the impression that the speakers are way way far from " time and pha... | |
| Jolida 302 b disaster Jolida 302 does not have bleeder resistors, just like most Chinese amps.Power up with no tubes and it will store B+ almost forever :) | |
| Quad ESL Cap mods The PCB is one sided, so you will need to carefully unscrew the mounting screws and flip it around and unsolder the orginal sand resistor and lytic.You will need special nylon tie wraps to tie the new (HUGE) lytic and bolt the tie wrap onto the la... | |
| What is “warmth” and how do you get it? @ Learsfool: Careful with Cary. That's the foggy yet non-linear sound which I couldnt deal with. Prima Luna varies from model to model, some are pretty good, some are thin and beamy.@Bryon: worry not about the mod, if you extract the stock cap car... | |
| What is “warmth” and how do you get it? Bryon,Many confuse foggy muddy systems that can only play one or two of Carol Kidd's ballads as the ultimate warm systems.Making a system foggy and rolled off masks the lack of dynamic linearity, stability, and distortion from transients. A tube p... |
