252/300
Posted by: Emil F on 26 July 2003
NAP 300 is coming next week. 250 is driving now the Mezzo. It’s not powerful enough.
There is some clipping at 11 o’clock. I tried 500 too. The speakers are breathing easier, voices and instruments have more body, superb control.
Interestingly, there is still clipping at 11 o’clock. The Mezzo is 250 W at 4 ohms. I’m going to believe that the speaker is falling to 3 and 2 ohms and then it needs much more power.
Unfortunately bi-amping is impossible.
Has somebody heard the new Krell KCTx/300cx? How does the combo compare to 252/300? Has it the PR&T of 250 at least?
Any opinions are highly appreciated.

Emil--
I've not heard the KCT but have heard the 300cx. Don't bother.
If the 500 won't drive them to sufficient levels then you either need to accept that, get different speakers, or sacrifice at least some of what you like in Naim amps.
Best,
Bob

Emil,
I had the same problem when I tried out mezzos driving them with 135s - clipping like mad which is unfortunate, but then I do like to play music loud. I ended up giving them back as I only had them out on loan.
Bob is right, get other amplifiers or another pair of speakers but at least get a system that matches. I know it's unfortunate as they do have some great qualities. Most importantly, enjoy finding the next componant.

a Bryston 4B-SST will do.

Krell pre and Gammut power won't clip!I have a friend who drives Gales 402b's (rebuilt) and they must be the worst to drive ever and he gets an enormous sound. Saying that I agree with a previous comment keep the Naims and get other speakers!

Emil,
The Mezzo's were one of the speakers I considered in my quest for new speakers.
I came to the conclussion that the Mezzo's were too demanding for Naim Amps, unless you considered multile 500's.
If it was me I would either change the amps or change the speakers.
Regards

Krells are not reknowned for PR&T. Look elsewhere. Personally I prefer Chord Electronics to Krell any day. Bryston is also a good option.
I have driven Mezzos with both 135s and 500. The 135s struggled but the 500 didn't. Going by my experience, I'd expect a 252/300 to be able to drive them. This was 3 years ago so perhaps they're more difficult to drive nowadays. The 500 would only struggle if the impedance dipped below 2 ohms.

Frank.

Now I am standing on a crossroad!
First thing I have to do is to give 300 time to break in and show its potential.
I believe that a system begins with the speakers. More than 10 years I’m listening to 3 way floorstanders, bass drivers 10“ to 12“.
If I keep the naim amps I have to change the speakers. Do you know a speaker, matching the a.m. criteria, price not under 6/7.000 UKP, which likes power amps with less watts and low damping factor?

Focal.JMLab uses YBA amps to demonstrate the Utopia range.
How good is YBA?

The new 300 arrived last night. From cold it outperformed 250: bigger sound stage, more weight, more natural, less noise, smoother treble, more bass.
And YES it can drive the Mezzos! The speakers disappeared.
I liked 300 more than 500 at the short test two weeks ago. Not that 500 is not better. 252 and the Burndies were not warmed up. So the 500.
My dealer spoke to JMLab about the clipping at high levels and the answer was that the speakers caused the problem.
That means that 250 is also powerful enough to drive the Mezzos.

Nice on Emil, keep us informed as to how that 300 is performing.
Happy listening

Well, time to share some experience.
Two months ago I replaced CDX2 with CDS3 and now I believe that the system: CDS3/252/300 has almost reached its potential. Together with the Mezzos they are showing perfect teamwork. The sound is impressive.
I made some useful tweaks: mains, splitting fraim in two racks, etc. The last tweak I did was very surprising. The binding terminals of the Mezzos have a function for additional tightenning of the banana plugs. I was using this function till last night. The sound opened up when I left the plugs loose. There was more of everything. The plugs must stay 'relaxed' in the terminals the same way as in the amp. Maybe this is connected with the stiffness of the cable? Relaxed plugs - less vibrations.
I think it will be a useful tweak for owners of speakers with tight or narrow terminals.
