Nuforce - Rattled

[Primalsea]

You might be experiencing that hifi thing of what may seem impressive initially starts to irritate over the long haul.

Yet... I compared it many times to the very popular Lyngdorf 2175 Integrated and the Nuforce was clearly better in key areas

Quite puzzling. I really don't know what to make of these comments about harsh/distorted treble from Class D amps.

I've had loads (well, quite a few! *) and if anything I'd say the "Class D House Sound" (a contentious concept! ) was rather over-smooth and a bit 'safe' in the treble.

And I'm mainly a classical music listener so I'd expect to be particularly sensitive to treble issues - I certainly can't stomach many speakers that are well thought of for rock/electronica.

Maybe I'm just deaf. ... although I am over 50 so treble sensitivity will undoubtedly be one the wain .... but then Martin Colloms ain't exactly a spring chicken!

Could it be that I tend to live way out in the 'backwoods' and away from so-called civilisation - so the background levels of RFI will be low?

* Veritas P400 stereo power, NuForce Reference 8 monos (their 1st amps, and allegedly the worst RFI offenders), Lyngdorf/TacT SDAi2175 integrated and SDA2175 power, T-Amp, modded T-amp. Any others? Possibly ...

It's more the quality rather than quantity of treble; as Martin Colloms pointed out we have to invent new terminology for Class D problems.

Hi Hans - well, I was talking about treble quality too. I just haven't heard treble nasties in any of the class D amps I have owned. Too damn smooth - yes; distortion, no.

[Togil]

I'm beginning to wonder if it was after the upgrade to the V2 version because I hadn't noticed it before either. Colloms reviewed V2.

Now with my old Audiolab things are back to "normal" - actually it's very good, a humble power amp with a high-class preamp can perform miracles, I almost feel like a box-swapper

[Filterlab]

Unusual, I've heard the NuForce amps and they are very impressive, in fact my next power amp change was to be moving from my modified 8000P to a pair of the 9SE V2s. I may have to have a pair on long-term test before making the jump, saying that the Audiolab stuff in normal guise was always leagues ahead of the competition, modified even better.

Hmmm.

[Togil]

Oh is there something to modify in the Audiolab ?

I'm using a 15year-old integrated in power amp mode.

If you post a pic of your updated Nuforce amps and if we can find a decent picture of the ones before it might be possible to work out what they changed and should give us an idea whats made it worse

Some mods/updates don't suit everybody

Hi chaps first e-mail here:

I have no problem with the Nuforces and certainly not headaches etc. I am a valve man at heart but when I don't want all that power on the nuforces are OK.
