Hi Fi volume not loud enough

Hi,I would appreciate some advice. I am no expert, but over the last few months i have bought the following second hand , but find full volume is ok but not loud, half volume is barely audible.NAD 5120 TurntableCambridge A5 AmplifierMission bookshelf speakers (25-75 w/ch)I have changed the pre amp a few times because i thought this could be the problem, but does not make it any louder. Latest pre amp is a NAD PP2Is it because the separates are not compatible, or are the amp or speakers not powerful enough ? Any thoughts greatly appreciatedthanksMyles

Something is broken. You need to test bit by bit to work out what it is - start with speakers.

 

Unless your a Saudi Prince your setup should easily fill your room.

Thanks for that. Stupid reply by me, but assume unless  i know someone with working speakers/ amp etc and i can test out through a process of elimination , then there is no other way of checking which part may be broken.

If you were electrically minded you could try a multi-meter at the end of the speaker cables which might tell you something.

 

You didn't indicate if you have any other sources - a TT cartridge at the end of its life can sound very feint. All you'd need is a 3.5mm to two phono lead and you could try your mp3 player/phone/computer into the amp to compare.

RE: Hi Fi volume not loud enough

If you have a turntable do you have a phono stage to go with it?

the cartridge is audio technica, and i recently replaced the stylus with an equivalent (cheaper!), although noise level was an issue before this.

re phono stage, is this not what the pre amp is for ? excuse my ignorance, my knowledge on this is very limited.

I don't know, do any of the pre-amps you've used have phono stages in them? It's not a given.

RE: Hi Fi volume not loud enough

NAD PP21 is a phono stage, so should be fine. Does sound like something is at fault though, the Cambridge Amp has approx 60 watt output, so shouldn't need it on full to get reasonable volume. What model are the Mission speakers? Can you describe how you've got it wired up etc? Ideally you could do with trying another source - even plug the TV into it if you can and have nothing else. Also, if you're using a phono stage it won't matter which input you plug it into on the amp (just not the phono input on the Cambridge if it has one) so I'd try a few inputs such as CD, aux, tuner etc to see if the issue lies with the input you are using.

 

Good luck!

Could be the phono stage or your wiring. Try another source, do you have a computer?

RE: Hi Fi volume not loud enough

Hi, thanks for the advice so far. This morning I have tried plugging the phono stage (pre amp) into both the cd and tuner inputs and changing to the appropriate setting on the front of the amp (didn't realise you could do this!), and it all works but at the same sound level as through the aux socket .Does this eliminate the amp as the problem?

I have checked my Mission bookshelf speakers and there is no model number, just 25-75 w/ch and 8 ohms. Noticed quite a few of these for sale on ebay etc, quite cheap! just got these connected + to + (red) and - to - (black) with the speaker connections on the amp.  

Any other thoughts ?

RE: Hi Fi volume not loud enough

How many binding posts do you have on the speakers, is it 2 or 4 on each one?

You need to try playing something else through the amp to either clear or convict the amp/phono pre-amp/turntable as the culprit. You surely must have *something* else you can plug in to the amp? It's not rocket-science, just a methodical process of elimination.

2 binding posts on each speaker.

RE: Hi Fi volume not loud enough

Plugging the phono into another selector on the amp won't do any good. Assuming you have the speakers wired up correctly, it could be the phono stage on your amp is faulty. You can buy phono amps for around £50 or the Rega one is about £80, maybe worth a punt. 

 

Do you not a lcd tv or computer?
