And how do we begin to covet, Ken? Do we seek out things to covet? No. We begin by coveting what we see at head-fi meets. I seem to recall electro-shock collars being brought up during the dinner conversation. Not sure if it was in this context or otherwise. :smiling_imp:

Thanks to @PJABBER for organizing and to all who brought gear. Being out of the "auditioning gear" game for a couple of years, there was a ton of stuff I hadn't heard. The Bottlehead Mainline has been around for a few years but I had not previously encountered one in the wild, so that was a...

Looks like I've got some unexpected availability this afternoon, so I will be there. Not bringing any gear (no time to get my act together), just coming to get caught up on what's new. I think it has been a couple of years since I've been to a meet. See y'all in a bit.

LME49724 is not a single opamp as typically used in audio devices. Never used one myself but it's definitely not going to be plug-and-play according to the linked datasheet. A standard single opamp like a NE5534 has the +V supply on pin 7 and the -V supply on pin 4. The LME49724MR is a...

K553 Pro is what I use at the office. They're inexpensive and don't leak much sound even when listening at decently loud volume. They're also easy to drive - pretty sensitive overall and the big biocellulose drivers make good bass without needing a monster amp. I run them off a Magni 3 which is...

They're not unbelievably weak, but they break probably a bit easier than most. I broke one leg off a MUSES 8920 when removing to install sockets in my TEAC UD-301 (the 8920 were the stock chips). It was kind of a pain due to the chips being fit pretty tightly to the board... PCB hole spacing...

The combo is pretty good. My T50RP are the MkII version, modified to make them listenable. I have modeling clay worked into the back of the baffles, earcups lined with acoustic foam and stuffed with drug store cotton sheet material which combined to effectively tame the ridiculous midrange echo...

I have a Crack with some mods as well as the CTH. Built the Crack a few years ago and have really enjoyed it with HD650s. Then I got some orthos (T50RP) that I modded to the point that they are actually listenable, but the Crack isn't a great match for those because they're 50 ohms and take a...

IIRC it outputs about 1 watt, and not many loudspeakers can be driven with real authority by 1 watt. EDIT: Nevermind. Forgot the MCTH doesn't have line outs. Your Personus are powered monitors with their own built-in amp. You could theoretically run the headphone out from the MCTH to the input...

So those of you who've already received yours ordered the +SDAC version [lemme see, when did that version drop? September?], while those of us who ordered the original amp-only version on the first day it dropped back in August have been sent to the back of the pack of massdrop's order...

Sounds like a different problem. These fuses are not the self-resetting type, and they don't work intermittently. They are either blown or they're fine.

I've never bought opamps from aliexpress or from any other source shipping from China. If it's a low price on an ordinarily expensive "audiophile approved" opamp (OPA627... cough cough) it's a fake, whether it's coming from China or elsewhere. Not that price is the only indicator (fakes can be...

I don't know anything specifically about your sound card, but my Audioengine D1 has the AK4396 DAC with just one dual-channel opamp driving either the line outs or headphone jack. Presumably you are aware that the LM4562 and LME49860 are dual channel opamps, but the LME49990 is a single. So if...

The stock fuses were 200 mA and I replaced them with 250 mA. Using a higher current replacement is not something I would ever do on a mains voltage line, but to supply this analog section they're running at lower voltage and seeing a fraction of an amp so I reasoned it was probably safe enough...

  High output impedance, in and of itself, is not a desirable trait in an amplifier. The BH Crack doesn't sound good because it has a high output impedance; it sounds good because it's an output transformer-less tube circuit, and a necessary limitation of "most" OTL tube amps (certainly those...

Problem is, the list of fully closed-back cans that don't have severely compromised SQ in one way or another (congested, echo-ey and generally closed-sounding, and/or basshead type cans that don't appeal to me) is already somewhat short, and only a fraction of those that don't suck are in the...

Thanks to PJABBER for organizing! It was good seeing everyone again and hearing some of the latest and greatest gear. I don't think I'd been to a meet since April-May of last year. I was obviously out of practice at packing up for these things, grabbed the wrong laptop and had to futz with...

It's darn close to 10" x 6". After assembling my wood base I measured the recess the plate sits in at approx 6 1/32" x 10 1/16" and that allows a slight gap all around.

Looks like I will be able to escape the house for a few hours! I'll be there, though possibly not right at the beginning.

I'll be making acoustic panels for my listening room sometime this spring. Roxul Safe-n-Sound rock wool type insulation framed out with some wood with some type of decorative fabric stretched over. Search the web for DIY acoustic panels to get an idea. The big box stores only carry that Roxul...

FTFY

Quote: The nasty pops are probably caused by a loose/intermittent connection. I went through a similar thing 2-3 weeks ago... hissing and pops in just the L channel. I had success with the chopstick method: operate the amp upside down while listening to some music with some headphones that...

  I recently received one (the piece on the right) from the same seller in Taiwan. I've only tried it in one device so far, an Audioengine D1. That was originally equipped with a single surface mounted 5532 between the DAC chip and headphones, but I have socketed it and tried a few other...

^^^ Do they make a version of those headphones with an integrated microphone & DSP that can actively null out the sound of a crying baby?

I can't commit to attending but we'll see how things are looking a month from now. We had our second kid 3 weeks ago so things are slightly hectic on the home front. I'd be toting my usual HD650 and Bottlehead Crack pairing, plus maybe my Fostex T50RPs and/or AKG K553s and a couple of sanely...
