Just upgraded from my old 70's integrated: To some 90s (I think) separates: I think I hosed up my epi 400 towers with the new amp, sadly. I had something wrong and a terrible howl came from the speakers, after which all the treble was gone. Got my 70's Polk monitor 7a's hooked up now and they still sound fantastic but it looks like a have a pandemic speaker repair project on my hands with the Epi towers large hands fucked around with this message at 23:03 on Apr 5, 2020 |

polyester concept posted:Love me some 70s aesthetic but it’s hard to go wrong with Sony ES Yeah, we're sad to lose the cool silverface amp with the blue *fluorscan* meter and huge knobs and levers in the livingroom where it felt like a cool piece of furniture but I'll keep it for a backup/den stereo. The preamp cost twice what the power amp did and weighs almost as much lol. It is indeed a motorized volume knob, wife freaked when it moved itself when she turned up the volume with the remote. The polks have been in the garage for years and I was going to give them away, but hearing them again I think I'm gonna get some teak veneer and a refoam kit and hang onto them: large hands fucked around with this message at 01:11 on Apr 6, 2020 |

Thanks, the n55 power amps seem like a good deal to me. 110w into 8ohms, bridgeable to 300w for a dual amp setup and go for around 200usd. I paid around twice that for the pre but it's a very nice one, I believe there are cheaper ES preamps out there.

polyester concept posted:Growing up in the 90s and into the 2000s, I had only seen Sony equipment that belonged in that latter category. I assumed they were just another crappy consumer brand, and it wasn’t until I got into hifi stuff much, much later that I realized they made some really good stuff. I remember them being department store stereos, stuff I'd look down on while saving up for NAD gear, but from what I've read the ES stuff from that era is more like Denon or something?

If any electronics guys in here are able to give me some guidance it would be a huge help. I opened up one of the Epi towers that I think I damaged while hooking up the new power amp the other day. Basically the speakers now sound like there's a blanket over them, no treble, muffled vocals looks like the previous owner replaced the caps and resistors when he put new posts on. I have access to a multimeter, and a tiny amp I could test individual drivers with but I have no idea what I should be looking for. Just to be clear there are 8 drivers per speaker, 2 pointing in each direction: large hands fucked around with this message at 18:46 on Apr 7, 2020 |

I don't know anything about modern Bose stuff except that it seems like a bit of a scam but a buddy has a pair of old 901s and they're beautiful and (I think) sound amazing. They're definitely unusual, I know they use the special equalizer thing, I'd forgotten about using the tape loop. I guess the equalizer has something to do with them just using what look like mid drivers. What's the "Bose sound", I've heard that term before

Very interesting read, thanks. I've always judged my system and speakers on how it sounds flat ("tone defeat" on my old NAD amps "source direct" on the current Sony preamp) I figured if I needed to adjust the bass or treble then the speakers or room weren't up to snuff. I've been playing a programming puzzle game recently where you build different embedded systems and program them with a made-up form of assembly. One of the puzzles early on is an "harmonic maximizer" that does basically that, this page from the manual subtly makes fun of the audio companies selling such things: large hands fucked around with this message at 20:37 on Apr 30, 2020 |

Chumbawumba4ever97 posted:I thought expensive needles were a scam until I got a VM540ML and all of the simbilance from the yelling of loud "S" sounds on all my early 90s rap records completely disappeared. That sounds more like an issue with your previous cartridge/stylus than something you need to spend hundreds to fix. Not that I have a problem with expensive cartridges, but stuff like that shouldn't be an issue on a decent inexpensive one.

They just look beautiful and I'm assuming sound great. Appearance is a big factor, if they're going in our livingroom they better be nice hardwood or my wife won't be happy. Are there attractive modern speakers with that aesthetic for less than $2000?

I haven't, I always just looked for classic used stuff assuming that new stuff that looked as nice would be out of my price range. I'll check some of those out. e: I think I probably assumed that they were like amplifiers, in that you can get a pair of speakers like those b&ws I linked that used to cost $5000 new for $1000 today, and they'll sound much the same as a pair of speakers that cost $5000 new today.

Exactly the kind of input i was looking for, thanks guys. Think I'm looking for floor standers both for furniture reasons and I've found most bookshelf speakers to be a little anemic in the bass range. Anything smaller than the Polk monitor 7s I've used in the past on stands would probably be out. Currently using a pair of energy 5.1e towers I've had since I was a teenager but I find the mid range lacking, don't like the chuffy ported sound and they're ugly as sin. These guys are a few blocks from me, hopefully they open the physical store soon and I can go listen to some of that monitor audio stuff https://www.soundhounds.com/collections/floorstanding-speakers

Hey electronics guys, maybe you can point me in the right direction, the other night my amp blew the tweeters on my towers while nothing was playing. During the day we'd heard a couple of loud zap sounds coming through the speakers. I should have unplugged them then but foolishly didn't. Later that night my wife heard a louder zap and the next morning the tweeters were out. The amp is the Sony ES power/pre combo I posted about buying a few pages back. The speakers were my old set of Energy 5.1e's. The pre was plugged into our turntable which was off and PC which was on and the input for the PC was selected on the pre. Pre was plugged into a Costco power bar and the power amp plugged into the outlet on the preamp. Luckily I don't really care about the speakers but I need to figure out what happened before I plug in a new pair, obviously.

Hey Turgid, thanks again for your help, finally got time to crack open the TA-N55ES:Discernibly Turgid posted:TA-N55ES stuff Was not expecting a red velvet platform for the caps lol: Audio test with a variable test tone shows both speakers affected, only the tweeters, they are completely dead, 6" drivers work fine. 1. after a couple minutes warmup, both channels show @5mV DC 2. adjusted left channel to 7.6, right channel to 7.1(those are some fiddly adjustments!) at noon. 12:30pm l= 7.6 r = 7.5 1:00pm l = 7.7 r = 7.1 1:30pm l = 7.8 r = 7.2 2:00pm l = 7.6 r = 7.2 So no real change there. 3.stk pins: d305 = 1.5V d306 = 0.9mV d310 = 2.5 mV d311 = 2.3 mV These are what I'm looking for, right: When testing the pins I'm just holding the black probe on the metal case to ground, is this correct? I noticed the values tended to start high then settle down to the numbers above.

Listen to some well mastered music and see what sounds best, but a good starting point would be as far apart as you can get them, centered on your listening position, canted in towards you a little (15° maybe) and a couple feet away from the back wall.

It's seriously crazy how much difference positioning and room acoustics can make. It sounds like bs but when you get it right the speakers disappear and the music comes from the whole side of the room. Personally I would have one where the lamp is to the left of the door and another where the plant is and go from there. e: yeah closer to the wall should be ok with front firing ports

Hey Turgid, the oscilloscope I tried to Jerry rig was an exercise in frustration so I bought a $30 scope from Amazon, here's the output with nothing plugged in: STK pins 5,6,10,11 all read @1.1V (other pins are around 50V, but I assume that's normal. I'll check the caps you mentioned with a multimeter next, although now I have a scope, would that be a better way to see something if they failed open? If people are annoyed by my ongoing attempts to fix my stupid power amp here, im happy to take it to PMs e: since I know nothing about oscilloscopes, the photo above was with the probe set to 10x. 1x result: large hands fucked around with this message at 18:49 on Aug 8, 2020 |
