Tri amp advice

You dont mention snaxo362 or a supercapdr to feed said snaxo

As John says, if you're not already running an active system with a snaxo362 and a supercapdr do that upgrade first.

Triple "triamp" without active crossover combines the large box count of active *without* the performance benefit. Otherwise known as a lose/lose situation. 

Oh, it's not that bad...

70% to 80% of the cost of a proper active crossover system.
5% to 10% of the benefit.

OK, maybe it is that bad! 

Arguably its worse cos you have a passive crossover being hammered by three amps (hopefully wired seperately) plus you have the signal earth issues of 2 more amps and the RFI issues of two more mains cables etc etc etc

I can see that possibility occurring sometimes.

Guys you cannot tri or bi amp any naim speaker without an active crossover. There is only one  pair of banana inputs on a naim passive crossover so it's either full blown active or passive - no wanna be waste of time and money biamping (or biwiring for that matter) like one can with other loudspeakers with multiple binding posts,

Zoot has mentioned on another thread that he has three 250.2s running actively. So clearly he has an active crossover, or he wouldn’t be able to play his music. Though whether this thread is about giving or seeking advice is not clear. 

A CDX2 and an NDX into an active NBL set up with 3 250s?

I'd be at least strapping a 555PS on to those sources (or replacing them with their better relatives) long, long, long before changing power amps.

If sticking solely with power amps though, I'd still do 3x 250DR and spend the rest on SCDR for the SNAXO and better sources.

Hope this helps, FT

My error, yes 362 and a newly recapped SC unfortunately not DRed yet.

Yes , that makes sense- here in the US  a DR conversion will probably take 2 months maybe more if I DR the SC might as well DR the three 250s, sounds exhausting and expensive. Visiting London in ten days hoping to get a tour at the factory if I'm lucky, thanks for the suggestions

It most definitely helps!

Seeking, btw I have an affinity for used gear ,the 250.2s sound so good, my dealer is great but generally doesn't come across used gear-

On the side line, soaking up info.

It appears the OP, has an fine Active system already in play:

552 DR

Snaxo 362~ NBL ~ 3 way design

3 x 250.2 waiting to be DRed!

SC 2~ waiting to be DRed.

So the question appears to be:

Does the OP invest in DRing his Amps

Vs

Beefing up his sources, as FT, has suggested!

Allante93!

PS. Nice Active System, Zoot!

Got NBLS love them, right now I want to either DR my three 250s,   Or  wait a while and get three 300DRs love my 552/DRed ,NDX,CDx2, LP12 this thing rocks hard, plays string quartets, singers come alive it gets better all the time better little changes in my listenroom like the addition of two corner bass traps - cohearent bass ,better timing more aliveness.....isn't this what drives us to find improvements the money is insane but it's worth it. Well worth the magic !

The NBL was designed with the old range of Naim Amps so should voice well with them, but the new range of Power Amps will certainly give a superior performance.

But with an Active system, maintaining system balance is very important and I'd say more obviously annoying if you get it wrong. Given you are enjoying what you have already it makes some sense to see if the source being upgraded gives you the next lift you are after, without spoiling the overall sound of the system you already enjoy, from your post.

The NDX to NDS seems the obvious thing to try to keep the Naim voicing and lift performance.

As you say, you can upgrade so many parts that you don't want to upgrade and reveal any system weakness. I'd try NDS-555PS, then DR for Supercap for Snaxo, as that really adds the fireworks to the performance. Then DR the 552 and the amp upgrades - the 300DR will be a big lift over the non-DR 250 and probably where I'd go. Somewhere in the above sequence trying a second 555DR PS on the NDS will be worthwhile, as you certainly will hear it on your system.

That's my take on it into the mix of advice you already have. I've run Naim Active systems for many decades and know how you can unbalance them with an upgrade in the wrong sequence - but home trial and really honest self-appraisal of 'is it better' always ensures you go in the right direction of enjoying spending your money.

Extreamly helpful DB, I think the NDS/555 plus DR on the SC maybe in the future a second 555? Headed to London maybe I can find a good used NDS?

Zoot,

that Bear, he speaks good sense.

Happy auditioning, FT!

NBL was voiced active, with 250. That’s quite important information to digest. 

So, make the Snaxo as good as possible (it’s quite sensitive) and use nothing but a Supercap. and add 250 to that mix.

The Briks were unique, in that they were designed with the upgrade path. 

That is their later models, I have the second to last model produced. 

It allowed for Passive Briks with one Amp, then passive Briks with two Amps , then passive Briks with three Amps then Active Briks with Linn's Active Crossover with Bingo Card, and Linn's Dirack PS, I think! 

its Been a long time! 

One thing for sure, I do favor Naim's Amps as opposed to the Linn's LK 280s, but Linn's Amps didn't have the famous Naim Hum! 

With that being said, can't wait for my next upgrade: 

SC to power the Snaxo, and the Snaxo shooting the three amps to the back of my Briks. 

Tweeter , Miss , Bass. 

Disregarding the passive crossover:

Allante93!

Finally got that Imgur to work, I think! 

PS.  No more photo Bucket! 

A Trip Down Memory Lane:

Entirely to much money invested in Music! LOL!!!!!

Nice to have a 2nd System, that's not Naim, helps keep one grounded! 

Enjoy Your Music, The Why!
