| 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... | |
| What is “warmth” and how do you get it? Hi Tmsorosk, may I ask if you are referring to acoustical "unplugged" music or electronically produced music as perhaps in a rock concert?I go to classical concerts and recitals often (actually almost every week these past couple months) and I fin... | |
| What is “warmth” and how do you get it? I think most can agree that reproduced music has warmth when violins dont sound like slaughtering poultry and piano transients dont sound like someone hitting your temple with a punching tool:So how do I pick a pc of gear of mod a pc of gear to ma... | |

| Jolida sj502a tube advice The layout of the Jolida 502 is, unlike Audio Research amps,so simple that an old-school TV repairman can easily mod with one sheet of instructions.No need for mega expensive mod shops, just a shopping list of components from ebay and mouser.com a... | |
| Jolida sj502a tube advice Tube rolling on this unit is a waste of money until you have addressed the obvious flaws:1. Ultralinear (unless you really need the power run it in triode mode)2. Coupling caps (get PIOs or Teflons for the 4 coupling caps)3. high voltage bypass @ ... | |
| Review: JM Labs Diva Utopia Be Speaker I dont think its only my specific pair of speakers.When I auditioned the Divas a few years ago at a dealer the "wooden" bass and the nasal sound was all there,and I am sure most owners and ex-owners would agree with me.Funny even the salesguy said... | |
| Review: JM Labs Diva Utopia Be Speaker What I meant to say was:A good intention to create destructive cancellation to calm the resonance might have been off-target and exacerbated the problem (more muddiness and more nasal sound) instead. | |
| Review: JM Labs Diva Utopia Be Speaker Thanks for the advice Shadorne. Dont feel there's any anomaly at 1k or so right now especially after I pulled the series notch filter. There used be a bass suck out and wooden "middiness" (in addition to low freq muddiness) to these speakers which... | |
| Review: JM Labs Diva Utopia Be Speaker Update: The mid bass dip and strange overtone actually appears courtesy of the series notch filter in the crossover board that connects to the 2 woofers (not the main Xover board where the speaker cables connect to, it's the board that's secured o... |
