sound downgrade

Oh come on its not snide. It was a fairly expensive one and I compared it with a bryston 4b-st and a naim nap 500. I am guessing it was £5k or so if that helps determine which model it was.

 

I still feel the 4 bst is better

 

Indeed - I prefer it to any of the above mentioned. So I bought 2! And a pair of 7b-st!

Just have to avoid the hit my neighbours have put out on me. ;-)

 

Amir,

in my experience, Krell with Dynaudio does a good impression of a posh PA system and shows neither component in their best light.

In all honesty, if you want to get the best out of the Dynaudios, I'd suggest either the new Primare kit or, for more excitement, olive Naim amplification. Many Dyns also work well with some switching amps, although this can be a tad clinical at times.

Whilst Bryston do make some powerful amplifiers, I have never been convinced of their suitability with the Audience range.

 

Thats very fair comments there Stereo

 

Never heard any dynaudio.

 

i agree that i were not satisfied by my system and i agree tubes are better in long listening but i love extension from top to bottom of solid and body of tubes but i can not spend so money for changing system. i should correct my system.

 

do you recommend accuphase 20w class A amplifier?

 

Amir,

Perhaps the Accuphase class A would be worth a shot. Not familiar with either it or the Krell. I think the Accuphase looks better FWIW!

You mentioned in your original post, and previously in other threads, that your electricity supply isn't very good. Have you had the opportunity to experiment with mains filters et el? If your supply is bad it may be causing problems downstream in the amplifier. May be worth your while speaking with someone who understands this stuff.

Regards,

Stuart.

 

poor mains quality .........will strangle any amp. Get that sorted first.

 

Which ways do you propose as best?

 

I'm buying van den hul main cable and isotek main filter.
do you recommend isotek filter?

 

So why is the thread about upgrading your power amp then?

 

Hi,

I wouldn't have a clue to be honest. I've always used my system plugged into normal household sockets/circuits. I do have a 'seperate spur' thingy for the Air con. which I'm going to pinch for the hi-fi as a trial. Just a little harmless nerdism to satisfy my curiosity.

Having never seriously looked into power conditioners and such like I really don't know what's meant to be good, bad or indifferent. There are a few people here on ZG that do use this stuff, including WM and his 'fairy dust' boxes, who ought to be able to offer some opinions for you.

Hope the Isotek and cable work for you.

Regards,

Stuart.

 

I leave my system on all the time - 24/7. Not only does it sound better all the time, it will also last longer as well, as the components are not subjected to the start up surge. The guys at rochester hifi have done so for years and thoroughly reccommend to do so.

I know krell have a clinical reputation, so perhaps you should get something more natural sounding to suit your tastes?

 

Mains filtering canmake a difference - however good lab grade filters neednt cost more than about £20 fitted inline. The difference is most noticeable on phono stages for obvious reasons. I am very skeptical about the rest but look forward to trying WMs "faerie box".

 

Don't know about the Krell characteristics, but if Dyn's sound harsh and forward then IME they simply need more power. See if you can try a (much) bigger amp and what happens then, but I reckon it might solve most of your current problems.

 

Erik,

Could you let us know what is about that offers a lot more than the 400wpc and huge current reserves the Krell has?

 

Eric,as StereoMic has said,current limiting and power shortages are one thing that even the baby Krell doesnt suffer from.

Read any one of the many test reports on it for that....in any case,moving from a 200W/ch amp to 400W,results in only 3dB increase in SPL from your speakers,and so on,so even moving to something like a Krell MRA would only result in a 9dB increase.

 

Yes I doubt more power is the answer - try a different amp.
