Some new gear, can't say I'm impressed

Yesterday I took delivery of a Denon DRAN5 and some Wharfedale Diamond 121 speakers, I've connected them together using 1.5mm speaker cable.

At low volumes everything seems ok, but once you get to a volume of 40 sounds start to distort, I'm guessing the volume goes up to 60. The speakers should be more than capable of dealing with the power output from the Denon.

Can anyone tell me if what I'm experiencing is normal?

RE: Some new gear, can't say I'm impressed

I guess you are doing one of these:

Overdriving the speakers with an underpowered amplifier

Using some bass boost

Getting towards the limit of the speakers

Expecting too much from a micro system and budget speakers

I quess you were expecting a little bit too much from the Denon DRA-N5. Nice system, little power.

RE: Some new gear, can't say I'm impressed

Yes it is quite normal , you have just reached the limit of the in built amplifiers capability to drive the speakers and the amplifier is clipping which is the distortion that you can hear .

Main system .

Electrocompaniet EMC 1 up , Monarchy Audio DIP, ECD 1 dac , EC4.8 preamp , 2x AW180 monoblock power amps , PMC Pb1i speakers .

RE: Some new gear, can't say I'm impressed

That all makes sense, but then why do the manufacturers not top the volume out at the point of clipping? i.e. why do they let you ramp it up to 60 when it starts to distort at 40?

 

I'm just confused that the amp is 65w per channel and the speakers are 100w per channel.

Its the amp. that is distorting the sound. Don't worry about what speaker w per channel are as long as they can handle it, the worst thing you can do to speakers is play distorted music. As for volume I think this may be to with what input you fed into it, so at say 40 for cd it will clip, also depends on the cd itself as some are much louder than others, try a quiet cd and see if it clips at 40? Really a £250 music system is going to compromised in many ways, its not like buying say a £250 amp.

I get that it wasn't an expensive system, although including the speakers it was £500.

It's replaced a sony mini system, which cost us something like £350, and you could turn it's volume right up to the max and it would never distort, but in saying that, the sony may have had lots of technology inside which altered the signals to the speakers.

RE: Some new gear, can't say I'm impressed

Yes amp. work in different ways, my old Arcam you could turn up to full volume and it did not distort but many modern amps seem to be full volume at about 12 oclock and after that they don't sound good. Also the speakers will be different from the Sony, maybe the Wharfedales are harder to drive?

 

Have you still got your Sony system, if so why not try it with the Wharfedales?

That's 65w at 4ohm. Then it's only 30w at 8ohm I think. (not exactly, just a guess)

Wharfedale Diamond 121 are not he most sensitive of speakers so that could be your problem. Can you take it back?

I'm starting to wish I'd gone for the Denon PMA520 Amp and the DNP720 Network player.

Oh..........those two will sound so much better than the DRA-N5. If I were you I would go back to the store and see if you can make a new deal  Wink

I bought the speakers from Superfi, got them cheaper (£200) as they were in the open box section of their website, and I bought the DRAN5 as a factory reconditioned unit for £200 instead of £269.

I believe Superhi have a returns policy not sure how it will work on factory recon. but maybe worth contacting them? Have you had it for more than 7 days?

RE: Some new gear, can't say I'm impressed

Return them under the distance selling regulations and go for the seperate amp and network player then.  No point hanging on to something that isn't giving you satisfaction.  If you can stretch to the PMA720AE, it is a bit of a gem.
