    DIY Cable Gallery!!

    Can anyone suggest something flexible, durable, and cheap for fixing my TF10s? I hear 24ga silicone "Spaghetti" wire is popular.

    Swapping or selling speakers? How much do I ask?

    Long story short: After a fix, I have myself a nice pair of these:     http://www.soundstage.com/revequip/cliffhanger_bulldog_followup.htm   And what I want is a pair of these:   http://audeze.com/audeze-lcd2-bamboo     The speakers are in good working condition, and...

    I Don't Understand You Subjective Guys

    Quote:   Quite the opposite. Speakers - especially electrostats - have widely varying impedance and can offer an inductive or capacitative load (or sometimes both at once!) A poorly-designed amplifier will choke on that sort of load.   Strictly speaking, I suspect that Carver used...

    Objectively "Good" Amps and DACs

    Quote:   The problem here is that these companies use a subjective design philosophy. This thread is about objective design, in which the entire signal path should ideally be a straight wire with gain.   There are some esoteric bugbears out there like intermodulation distortion on...

    The Holy Grail...

    Square wave in. Square wave out.    There are several packages for audio measurement popular with speaker DIYers - HOLM impulse is a big one. You'd need an unusual measurement rig, though.

    Objectively "Good" Amps and DACs

    An objectively "good" amp, as I would describe it, is the one in the LME49600 application note. Quite a few commercial and kit designs use variants of it, and the original uses a top-spec (LME49200) op-amp and has a DC servo. Powerful, low distortion, low output impedance,  and devoid of the...

    Ultimate Ears Triple Fi 10 Thread

    In a moment of madness, I shoehorned the triple-flange fittings from my old E3Cs onto my TF10s. It's obviously not an ideal arrangement by any means, but the improvement is easily audible, especially in the bass. Anyone know where I can get these in TF10 size?   Quote:   The TF10s are...

    Home-Made IEMs

    Has anyone here tried building a measurement jig for these? Stands to reason there's no reason you couldn't plug the data into a standard crossover design program (like PCD, which is free!) and make a really excellent IEM.

    Casting custom eartips for IEMs?

    So far, here's my plan of action:   Step 1: Use handy ear-foam casting kit to make a positive mold of my ear. Alternately, I can use one of the "press goop into your ears" earplug kits, which is less precise but may make for easier molding. Suggestions?       Step 2: Create...

    Casting custom eartips for IEMs?

    I've just acquired a new pair of Triple.Fis, and am enjoying them immensely. However, they're far from the most comfortable IEMs, and I've found that the Comply eartips don't provide as good a seal. Could this perhaps be improved by some custom eartips?   I have access to various casting...

    Does anyone know how I can replicate the internal cotton and plastic bits from some Beyerdynamic DT770s?

    I'm working on some custom DT770s made of wood and aluminum. (Plastic? We don't need no steenking plastic!)   Anywho, I have some DT770 drivers, but I'm missing the little plastic "crown" and surrounding foam. Does anyone have any tips on recreating this? I do have the driver assembly and...

    Worst "high-end" equipment you've heard

    Quote:   I'm not too familiar with Hirsch, but I might point out that until fairly recently, the only two parameters measured were on-axis frequency response and distortion.   To get an accurate picture of a speaker, you need to measure: -Off-axis response in both the horizontal and...

    Worst "high-end" equipment you've heard

    Quote:   "Not going to name anyone," eh? Yes, I have not listened to any other Grado products, and for good reason. However, I *have* looked at the measurements for a variety of their headphones - the frequency response spike that gets on my nerves is there in all of 'em. This is what...
