I recently moved. TO avoid any problems, I unplugged each piece of equipment and drove them separately to my new house 5 miles aways.
After 6 months, I am trying to set up my system and I am only getting STATIC out of one speaker and nothing out of the other. Can anyone suggest the least painful approach to finding the problem?
I really don't want to take it all apart and test each piece separately.
I have magnepan 12s, aes six pacs, Audible Illusion pre amp, Bel canto dac 3, squeeze box, and anti-cables (hard to work with)
i really don't understand why I am getting static??? I have another preamp and dac that I can swap in. What is the easiest way to diagnose the problem????????
Follow Ups:
Can anyone let me know if I could use the speakers linked below to test my system? So far, I have swapped out the pre-amp, squeezbox, and dac.
Now, I want try swapping out the magnepans.

March 3rd update. Tried a new dac and pre amp. Neither one worked. Is there a simple test speaker that I could buy? Or simple front end with coaxial or Toslink?
...and see if that works. Sure sounds like a front end problem.
I tried dvd player. it still doesn't work. Thanks
https://lyrion.org/getting-started/I thought my Squeezebox Touch had given up the ghost.
I installed a modem / router booster with ethernet outputs near the equipment rack and connected a CAT 7 S/FTP (shielded twisted pairs) ethernet cable from the booster to the Squeezebox Touch then upgraded with the above lyrion software.
After four years of ownership and when they were still located in nearby Pleasanton California my M3 preamplifier's dual mono attenuators became scratchy. They claimed the attenuator contact issue was "just normal ware and tear."They quoted attenuator replacement at $400 each or a complete main board revision which included new attenuators and a noticeably improved sound for $1400.
They assured me they had both the attenuators and the board on hand and the work would be completed within two weeks.Over nine months later I sent them a confirmed delivery registered letter demanding the immediate return of the preamp and the $1400. Living in the same County I began a small claims suit. The preamp was shipped eight days later. It did have a new main board. I found, if any improvement in fidelity, extremely subjective at best and sold it.

Swapped out the preamp. Still doesn't work. No sound. No static. I am going to try swapping the tubes in the preamp. Do tubes stop working just because of age?
I am try swapping out the dac. But the current Bel canto dac is giving a green light for bits received.
I hope that the problem is upstream. I find it hard to believe that both speakers or both mono blocks died just due to lack of use over 6 months.
Doubtful both monos or both speaker or both cablea would not work. If you have ruled out the preamp that leaves the dac or squeez box. I would pick up a used dvd player with rca outs at a second hand store and put in a cd or dvd.Also double check all settings of the dac and squeez box. Come to think of it that's what I would do first.

You can hook up the cell phone to SixPacs using this adapter. In case there is no jack, you can use an USB DAC dongle. Good luck.
One issue that I had some time ago took me a while to figure out. I turned on the system and suddenly, it didn't work for music. I checked everything. Rebooted the RPi4 etc. Finally, I realized my Topping DAC had been turned off and when it comes up, it defaults to another source. All I had to do was to select the USB connection and bingo, done.
Check you DAC to be sure it's listening from your streamer.

Does squeeze box have volume control?
Can you go directly from DAC to amps?
I have 105 year old tubes, doubt all your tubes would just keel over.
Sanity check on all the fuses?

You probably already covered this suggestion, but removing and reseat the tubes in pre amp.
I have one set of tube amps that the small driver tubes just wiggle free on there own just sitting on shelf
I've never played around with a Logitech Squeeze Box but from what I've read it has enough output options to use or bypass a lot of components in your system.
Looks like you can:
Hook up to your Dac
Bypass Dac straight into your preamp
Bypass Dac and Preamp and hook up direct to your Power Amps
Maybe someone else who knows more about the Squeeze Box can chime in as I'm not aware of/if any dangers troubleshooting this way.
Might also be a way to test the Squeeze Box itself.
Good luck and keep at it. Usually ends up being something simple. Especially if no evidence of flames, burn marks or smells.

Thanks for the suggestion. The squeezbox touch does have digital audio control and rca output. Unfortunately, I don't have an interconnector that is compatible with rca. I do have an even older squeezebox streamer but I doubt it works.
I literally moved the entire system 5 miles by itself over 3 or 4 trips. If that caused the system to break, I might have to quit this hobby.
I moved a B&O receiver that was working for years in one room of the basement, to different room. It never worked after it was moved.

Thanks everyone. I tried to reseating all of the connections and switching the dac connection from coaxial to digital and back again. I also tried multiple inputs and outputs for the preamp.
Anyway, I am not getting any sound out of either channel now. I hope it is just that the preamp tubes need to be replaced. I am going to try to swap out the pre amp tomorrow.
Thanks again. I just hate this part of the hobby. Tubes are great. But they are fragile and setting them up sucks. I just was confused why I would only get static and not music + static.
You can buy a new cheap Chinese made preamp and class d amp for less than $100 each and substitute each component in order to eliminate a possible problem with either component. The bonus is that you will have spare components.

I work on a lot of equipment, one thing that I use quite a bit is a cheap pair of speakers, you can pick some up at yard sale, goodwill etc for about $10. Connect the speakers to your amps, nothing on the input of the amp. Use a small screw driver or a wire, touch the inner conductor or the input, one channel at a time. Use your body as a source, meaning touch your finger to the wire or small screw driver shaft, you will get a loud rude sound out of the speaker telling you that amp channel works. You can also just plug a cable into the input and touch the other end center conductor. Do same test on the other channel. If you get sound out of both, then connect preamp to amp, select a line level input like DAC and do the same thing you are now testing the preamp. If that works both channels you have a DAC problem or whatever you normally feed the preamp.
If you have access to other (cheap) gear, I'd start by trying different speakers, and then work back up the chain.
Where are you located? If local, I'd be more than happy to come over and help.
Thanks for the offer.
Probably less time than it took to drive them five miles each. I would start with source first and speakers second. Do you have anything with rca audio outs like a cd or dvd player?
it might be possible that unless the speakers were shorted at the amplifier connection, movement might have caused damage . easy to check by just hooking up the working channel to the static channel.
good luck.
With the preamp, rotate all the front panel controls fully to each side about 15 times, including the switches, all with power off. Make sure the power supply cable is seated fully.
Will give it a shot. Have you had a similar problem with audible illusion?
No, but your gear has been unused for 6+ months. Switches & controls haven't moved in that time and the wipers could have debris on them.
I had a noisy volume knob which electrical contact cleaner didn't help. I then took the internet advice to try wd40 and got perfectly quiet results. I was very surprised.
Also you might try another source to eliminate the dac as the culprit.
Double check all your interconnect & speaker cable connections.
Do you have another set of speakers to test in order to rule out the Maggies?
Pop the top of the preamp and re-seat the tubes. Also on the amps.
I have never dealt with planar speakers, so take this with a big grain of salt, but they have always seemed kind of fragile and complicated to me. Maybe they got damaged or something dislodged in the move. Normally I would not think of speakers first, but you might try a quick experiment with a pair of conventional passive box speakers just to rule it out.
After that, I suggest the usual troubleshooting routine: first remove and reseat all cable connections, tubes, and fuses, checking for shorts and polarity, and reboot everything. Then, as others have recommended in this thread, begin with your source components and methodically work your way downstream, piece by piece.
You have some excellent gear. I'm sure it will sound terrific once you get the bugs worked out.
. . . in theory, practice and theory are the same; in practice, they are different . . .
You made no mention of what troubleshooting steps you have already taken.Simplify, divide and conquer (half splitting), isolate.
OR - You can take the blindfolded shotgun approach as many amateurs would do;-)

Abe has it right. Step by step.
First, simply go speak with another person, perhaps the postal worker outside.
Do you still have the same audio problem?
.
/ optimally proportioned triangles are our friends
for quick diagnosis you'll have to test each piece separately
Phone, laptop, DAP, whatever.
At leas you will know if issue is at the source or front.
KP
thanks. any idea why i would only hear static and no music??
Not until you find the culprit device or cable.
Go step by step, swapping channels, beginning with DAC-to-preamp, until the static moves from one channel to the other. The component/cable in front of the swap is culpable.
