Did I damage my new amp


So, as posted elsewhere, I bought new Monitor Audio Gold 300 speakers which I am still waiting to receive. I was impressed by the Arcam SA30 during the audition so I brought one home to pair with the speakers whenever I get them. In the meantime I am using my 20 year old MA Silver S8’s

Being new to streaming it took some playing around before I figured everything out. But one big mistake was not understanding that the volume on my iPhone also effects the amp volume.

Long story short, I managed to crank the volume on the amp to 100% for a few seconds before I understood what was happening, and got it turned down. ( I found the max. volume setting after the fact)

Since then I find my speakers a bit distorted. Now, I don’t know if they sounded like that with the old amp. Am I just over analysing things, paying TOO much attention to details as it’s a new amp and I’m listening too hard for an improvement, or I damaged the speakers or the amp. It sounds fine with jazz but something more in the progressive rock style and it sounds distorted.

I would like to think that if the amp was in danger it would shut itself down before anything would get damaged. And it was really only a few seconds. I probably will not see my new speakers until next week so I can’t compare with anything and this is got me totally depressed thinking it’s the amp.

What do you all think?

At this point, step by step diagnosis is possible. Any diagnosis/repair: Step by step, change only 1 thing at a time.

a. amp damaged?

tv speakers will reveal that. nearly everyone doubt’s that, you will know when you hook up the tv speakers.

b. one MA speaker? or both MA speakers? if amp ok.

Hook up one MA, one tv speaker: noise from that MA speaker? switch sides, noise from other MA speaker, i.e. one side or both sides?.

Now you know which speaker(s) are problematic

c. Fix MA’s to sell: determine the problem(s), decide if fix? Hifishark: they are worth decent $ if working.

Monitor Audio is still in business, they can help, some diagnosis first.

c1. might be only single driver (typically tweeter).

c2. might be crossover part(s)

c3. might be both.

d. both MA speakers, or only one (hopefully only one).

d1. grilles off, low but enough volume: listen carefully to each of the 4 drivers, both L & R; as well as feel the vibration of the lower three.

feel tweeter movement IF you can, sometimes not feel them moving but working, properly or damaged, or not.

e. IF from only one side (good news), you can move good drivers from good side to the problematic side. ONE AT A TIME.

 

e1. after driver move: no noise: driver only.

e2. find original, OR substitute drivers can easily be found and replaced

f. noise persists: crossover part(s) damaged

Time to get Monitor Audio involved

f1. Personally, I would stop, make some notes, deal with crossover(s) now or later. Or never. Depends on your or a friend’s skills.

f2. Where Crossover? (To Know what is involved). Monitor Audio tells you, IF they don’t:

remove bottom or two bottom drivers, find crossover location, and IF crossover parts all in one place, or some hither, others thither. AND, are crossover parts on a board that can be removed, fixed, replaced? Or, some are parts glued to the inside surface(s).

f3. IF all on one removable board, you could mark/cut wires to drivers, and send only the crossover board to Monitor Audio, or another party to repair/upgrade.

f4. One removable Board or Scattered Parts

I just restored another pair of AR-2ax’s. Single board, removable. Out, fix, back in, easy.

JSE Model 2’s, bunch of parts hot glued hither and thither, PITA.

good luck, hope it’s fairly easy to fix.

 

 

I hope you sort this out. But here’s one little tip for you. If your streaming involves using the volume control on your phone, you aren’t doing it right.
 

which brings me to a side question. 
Is there a way to have the iPhone or iPad volume to NOT move when adjusting the actual amp dial or remote? I should think the phone/pad should remain at the middle or lower and adjust the amp?

Not to derail my own thread though.

If you are using an app like Lumin, Sense or some other streamer app, you can fix the volume. What are you using to stream?

The Focals are in place. My wife is still sleeping so I can’t play at a decent volume yet.
 

But I should have thought of this yesterday. I plugged in my headphones and I think it sounds ok. You know how it is now, my mind will be messing me up for days thinking I’m hearing or not hearing all sorts of stuff.

If you are using an app like Lumin, Sense or some other streamer app, you can fix the volume. What are you using to stream?
 

Just my iPhone or iPad and the Arcam
