    New AIYIMA MM/MC Phono Preamplifier

    lc5. these seem to be an update to the lc2, (nla, as far as i know), that i have in one of my a07max's. they're a bit unwieldy; i had to make a special cover w/holes cut into it. the newer iterations are even larger still; they wouldn't fit into my amp. i got a 2nd pair for my other a07max...

    New AIYIMA MM/MC Phono Preamplifier

    you might want to give akliam opamps a try. after looking into opamps for my a07 max, i decided to give them a go, as they were significantly less expensive, and several reviews said they were either as good or better than the muses... doug s.

    Aiyima A07 Max Amplifier Review

    this is patently false. there are hardly any, (if any?), people(s?) who prefer the sound of either fosi over aiyima. almost all choose one amp over the other due to aesthetics, or slightly different feature implementation. it's pretty-much unanimous that both brands offer similar, if not...

    Børresen M1

    this is my idea of true full-range sound on the (relative) cheap: oris 150 horns, presently utilizing tang band w8-1772 drivers, (supposedly over-achievers compared to the spendy stuff). they do sound good. the horns are sitting on heavily modified klipsch lascala bass bins w/beefed up...

    Bricks List: 36V & 48V Power Supplies (for Fosi, Aiyima etc.)

    no; fan or fanless had absolutely nothing to do w/my decision. my decision was solely based on the fact that i think either p/s is total overkill for my speakers, which are ~100db-efficient. if i were wanting these better power supplies, and if i were using inefficient speakers, i'd certainly...

    Tekton M-Lore Speaker Review

    i've only heard one model of the tektons - the original double impacts, when they 1st came out. they sounded great, especially at their given price point. would i ever buy them? no. why? the same reason why i would never buy a tesla. the same reason why i would never shop amazon. the same...

    Bricks List: 36V & 48V Power Supplies (for Fosi, Aiyima etc.)

    i considered meanwell power supplies, (the ones i was considering had fans; this model might be better because it's fanless). i think they're excellent, at least from what i heard about them. but for my use, i think they're overkill, as i'm using very efficient speakers. so, i think the 5a/48v...

    Aiyima A70 Mono - Leaked?

    24db/octave is a steep enough slope. no, i cannot locate the subs, but the soundstaging itself is wider when the subs are stereo. i'm presently at 60hz x-over, i've gone as high as 80. (once for a pair of speakers i was auditioning for a friend, i went to 125, because the speakers had such...

    Aiyima A70 Mono - Leaked?

    my experience has been that, when subs are set up for stereo, there's an improvement in the soundstaging. it's recording dependent, but you can definitely hear it on some recordings. best mono sub placement i've heard is when the sub is directly centered between the speakers, and in the...

    Aiyima A70 Mono - Leaked?

    many people run stereo subs. this makes a whole lot of sense to me. what makes no sense to me is not including a hi-pass option w/variable x-over for the main speakers. doug s,

    Aiyima A70 Mono - Leaked?

    it simplifies life for those who want an easy way to hi-pass their main speakers when using subs. wrong - i was mistaken. this amp is sorely lacking because of this. one of the main advantages of using subs is to hi-pass the main speakers so they and their amp(s) don't have to see the lowest...

    Aiyima A70 Mono - Leaked?

    and if you plug l & r channels into them, you get summed mono bass. doug s.

    Aiyima A70 Mono - Leaked?

    edit; it seems i was mistaken; these amps have no high pass cut-off. which is a shame. and ridiculous, honestly. a main benefit to using subs is that actively crossing over the main speakers will improve them and the amps driving them as well as giving you better bass. disagree completely...

    New wideband compression driver - Celestion Axi2050 (300-20K, no crossover)

    i'm digging up an old thread from the depths because i own a pair of oris 150 horns and was considering a quite expensive driver upgrade - even if i purchase used. i came across this fellow who loved his tri-amped oris 150 horns for 10 years, and then happened to hear a pair of the klipsch...

    Fosi Audio's First Dual-Mode Balanced Amplifier ZA3

    neither is there is almost all amps. perhaps it's a language barrier, but i suspect that's what fosi meant by its elimination of the load dependency in its earlier v3 stereo amp. that's certainly how i interpreted it. my bad if i'm wrong... doug s.

    Fosi ZA3 TPA3255 Mono/Stereo Switchable Amplifier, and vs Aiyima A07 Max

    yes, the thiels were very nice. i sold mine quite some time ago. i know they had a reputation for being bright, but i never thought that to be true. i've always wanted to try the 3.6's but never have had the opportunity. now, i think i've got too many speakers to take on another set unless it...
