I'm having a buzzing issue with the Fosi X2 preamp I just picked up. I get a loud buzz anytime the preamp is hooked up to the turntable. When I try to google how to troubleshoot this all of the articles seem to be written for professional electricians. I live in an old house with lovely power but I figure if power was the issue then it would have presented before the preamp was installed. Equipment: Fluance RT81 Old Pioneer SXS525 Fosi X2 Preamp Some lovely RCA cables I bought from the hardware store Previous configuration (no buzz): turntable connected to phono input on receiver via rca + a ground wire between turntable and receiver. New configuration (loud buzz): turntable connected to preamp via rca + ground wire between turntable and preamp. Preamp connected to receiver via rca. My biggest lead is that if I touch the outside, plastic part of the RCA cable between the turntable and the preamp, and also something grounded like the chassis of the receiver, the buzzing lessens substantially. Removing the ground cable doesn't really seem to do anything at all. Is it the cables picking up some kind of interference? edit: I found some different rca cables laying around that I subbed in for the ones between the turntable and preamp. It was lovely cables! mega dy fucked around with this message at 02:47 on Jul 17, 2022 |

Now that I've discovered this thread, I may as well post my hardware. I originally inherited a bunch of 90s stuff when my dad passed away a few years ago. Receiver was a Kenwood KA-5020 and the turntable was a Technics SL-BD22. I got some cheap Pioneer speakers from Goodwill, then some other cheap Pioneer speakers off of Craigslist, and they served me well enough. The latter are CS-G203s and I like the look but I've been told that Pioneer has never made a good speaker. At some point I found a beautiful Pioneer SX-680 receiver at my local Half-Price Books for $200 and grabbed it. It sounds amazing. I picked up some Advent speakers as well: So that's where I'm at right now. I think it all sounds great and eventually I might pick up something higher-wattage or a turntable that can take a better stylus but I'm happy with what I have at the moment.

Where is the line between this thread and ridicule audiophiles? I never know which one to post in. People in this thread buy garbage (no offense but it's literally people's garbage usually) and people in the other thread buy snakeoil. This weekend I got a new receiver (x3700h from A4L) I played around with the setup and did room correction on both sets of my speakers and saved profiles for them both. Heres the before if anyone is interested how Kef R300 vs Dynaudio Focus 160 measure in the same room.   Then I listened to some tunes. Original 1972 pressing of Eat A Peach  VinylMePlease remaster of Aretha Franklin - I Never Loved a Man the Way I Love You

I surely consider myself on the spectrum as far as audiophiles go. Have a decent vinyl setup and collection and really enjoy it, but I do most of my listening as digital streaming (not even in high res!, 320kbit mp3!!) End of the day it shouldn't matter what format you listen to, or how much money you spend on speakers or equipment. It should be about enjoying the music coming out of your speakers.

Then the internet exploded and most of the obscure records I have can be found on youtube. I never thought the internet would grow so fast.

I have two espresso machines:  The one on the left is a La Pavoni Europiccola lever machine from like the 70s. The one on the right is a contemporary Izzo that’s a couple years old. The Europiccola makes objectively worse coffee, but has an incredible sounding whistle on the boiler and the human-actuated press is so satisfying to use, and the electronics are literally just a boiler inside with no PID or computer or anything, about as complex as a kettle. I love it. It’s functional sculpture, and I get satisfaction from it as a design object the same way I do a bank of tubes in an amp. I think the difference in this thread from the audiophiles thread is that nobody is pretending, there’s just more to appreciate in the aesthetic or the tactile nature of vinyl or the appreciation for simple or historic technology beyond ‘only’ the sound.

What’s the big to-do about Luxman gear? I’ve seen and felt it in person and none of it looked or felt particularly special to me. Felt on-par with its contemporary Onkyo/Rotel/NAD brethren and didn’t seem to do a better job functionally either. Didn’t seem bad, I just don’t get the obsession with it the way I do other cohorts of equipment.

Luxman pre-Alpine buy-out (mid eighties?) is very well regarded. The suckface stuff is also very unique, but it's really their earlier gear that had the great reputation.

Their old stuff was high quality and classic, they were bought by alpine in the 80’s and all their stuff was pretty standard mid quality for the time, similar to contemporary NAD, Rotel, etc… then at some time in the 2000’s they went seriously up market, think Accuphase/Krell. Basically a cool old name and the current stuff is high quality and very expensive but there’s zero shared DNA with the affordable used stuff.

Enos Cabell posted:A composite to HDMI converter should work https://www.amazon.com/s?k=composite+to+hdmi+converter. This came in yesterday and seems to work great. I have a choice to upscale to either 720 or 1080. 720 looks better - I think 1080 is just trying to go too far from the source resolution. That being said, to quote my wife, "it looks like poo poo!" I think we're just so spoiled by modern high-def features that going back to 480 is difficult other than for novelty purposes. On the plus side, after messing with some of the brightness and color settings on my TV it doesn't look bad at all. Watched most of Star Wars last night, pre-Special Edition Star Wars, and several of the changes I had honestly forgotten about. It was pretty awesome. My question is: right now I'm going straight from the LD player to the adapter with a video composite cable. If I use S-video would there be any improvement? I don't know what use S-video was and if it passes a better signal than a standard video cable, and I don't have one handy (at least I can't find one in my random bin of cables) to test.

S-Video should be a significant improvement, IIRC it separates R G and B vs compositing them into one stream.

S-video only breaks out one of the signals from composite IIRC. It’s definitely better then composite but not as good as component or RGB. I have to ask: does the LD player not have component out? I have a rip of the original trilogy laserdisc somewhere in 1080 that looks really good. Han shoots first and everything. My brother showed it in his inaugural movie night of his new home theater room and it looked crazy good (in pictures, I wasn’t there) Well crap… I’m sorry for spreading misinformation.

E: I stand corrected. I didn't know Laserdisc didn't have S-video encoded directly on the disc, so it goes through some processing in the player. Definitely go with what the poster below me posted. I was going off what I knew of other formats that do S-Video properly Mederlock fucked around with this message at 17:08 on Jul 20, 2022 |

namlosh posted:S-video only breaks out one of the signals from composite IIRC. It’s definitely better then composite but not as good as component or RGB. Component isn't really possible with LD due to how it is made. LD is recorded in composite format so you would have to add an entire extra electronic section to take the composite filtered to S-Video and then decode and mix the chroma signals to form the component output. It is one of the reasons why upconverters are around actually. Really even S-Video isn't great out of 95% of LD players. You are better off with standard composite signal out and then let your television, which old CRTs were great at or a good upconverter especially on a modern screen to do the filtering and whatnot.

Laserdisc is a composite video format. If you use s-video, you're basically just trusting that the comb filter in the player itself is better than the one in your HDMI converter. Lots of people in the LD community will say that s-video is worthless these days since comb filters in modern electronics have surpassed the ones from the 90s. It's possible you'll see a difference but don't hold your breath. Personally I don't bother and just use composite. And there don't even exist LD players with component because that would be silly. e:f;b

That's fascinating to me. I bought this adapter/upconverter but I'm assuming a ten dollar thing I bought off of Amazon isn't going to be the best. It's probably 'good enough' for now but I might start looking into what a real upconverter would cost and how it would work. In the meantime I'm going to enjoy the one true Return of the Jedi.

They're basically the same chip that gets put into modern TVs that have composite-in, I believe. You should see a decent upgrade from the RF you're using currently. Though if it's like mine, you'll have to tell your TV to un-stretch the video. Honestly expensive upscalers will quickly reach the point of diminishing returns when you're dealing with soft video over composite. Some of them will deinterlace better, help with colors/contrast, or have different filters that will look better/worse. They're much more useful for old video games which have straight lines and pixel edges.

Though if it's like mine, you'll have to tell your TV to un-stretch the video. Depends on the scaler. There is a lot of stuff, especially older ones, that are designed for dealing with soft video. They aren't popular with retrogames because they have significant latency. There has been a lot of interest and effort into making scalers for retrogames in the last few years so they have been focused on the needs for those devices where prior ones were designed mainly for video. There are still very high end scalers mainly for archival work being made but they are out of the price range for the average person.

I’ve got a turntable where one of the headshell wires is loose and it slides off half the time when it returns. I can’t crimp it enough to make it stay on for whatever reason. I obviously don’t want to solder it on but is there something I could do to get it to bite better? Sand the terminal a little or put something tacky on there? I’ve used alcohol to remove any oil that might have been on there.

I have an (Orbit) turntable with built-in preamp that works fine. I'm now connecting it to my new receiver and when I put it in the Phono inputs I get a horrible buzzing (with preamp on or off). I note the receiver has a ground terminal by the phono inputs. The turntable has no ground connection on it. When I plug the turntable into the generic RCA audio inputs instead, everything sounds great. Should I just leave it like that?
