Active Briks advice sought

Arthur --

I'm in a similar position: I've got a NAXO 3-6 feeding 2 x 135 on the treble and 2 x 250 for the bass and midrange. It seems a bit odd having the 135s driving the tweeters, but then again, they do handle the widest frequency range of all the drive units in the briks, and bandwidth is what it's about. When the system was first set up like this the treble becomes over-bright, the 135s effectively increasing the tweeters' volume relative to the 250s. However, fiddling about with the NAXO's HF pots cures this.

I'll work my way up to a six-pack eventually, but mixing is only worth it if this (the six-pack) is your ultimate goal. If you can get a job lot of used 135s and then have them re-capped, then I'd say go for it!

Cheers,

Tim

Instead of buying a six pack plus all the other stuff, why not go for a Nap 500.

Arthur asked for the most cost-effective amplification method. A second-hand six-pack (old-style) can be had for about GBP 4500, including re-capping, as against GBP 10000 for a NAP 500

A second hand Nap500 can be had for £6500-£7000

Mick:

While I have not excluded getting a Nap500. They aren't available used over the pond. I've yet to see one come up for sale in the US. Don't much like the idea of buying one overseas either.

I was thinking more along the lines of:

is a six pack of older(ser# 10,000-50,000), but recapped 135's, better than current vintage 3 X 250's(ser# 175,000 +)? Seems they would be somewhere around the same price.

BTW. I liked your photos. My mental picture of you and your digs was just about the same, just missing the cap and the glass of whiskey. Now, where's Mrs. Mick?

What's left to discuss?

£9300....

A pair of good Briks, £700. Three LK280, £750. A Linn Aktiv, £200.

£1650. That leaves you with over £7500 to do something else with.

And you have 480Wpc to impress your mates with...

350W of Class A implies an idle of at least 700W. That's 1.4KW at idle. Not very comfortable in the summer. If the amps are in the speakers I imagine they need fans and you have to be sure you're not setting the curtains on fire.

Usually when manufacturers say 'Class A' they don't mean it.

Guys/Chaps:

I've already got the Brik's, Naxo, and HiCap. I've even got most of the Naca5 I need. I've even got the XLR's. Mostly I was looking for a recommendation on NAIM amps (i.e. 135's X 6 or 250 X 3, or 180 X 3, 110, 90, etal-old style, new style).

The Linn solution seems like an easy and cheap fix, but I was looking for a Naim solution.

If I was going to spend 10,000 quid I'd get a NAP500.

The Mana can wait until later.

I'm already pretty good at spending a lot of money on my own. I don't need any help here. What I need is recommendations on spending a little money.

Arthur Bye

Three NAP250s. But if you can afford a six pack then problem solved.

I have an aesthetic preference for three amps...

James, I really hope the the ATCs don't have 350W of Class A amplification, because:

a) the heat will kill you

b) the electricity bill will bankrupt you

c) the ATC's smallish heatsinks suggest that with around 800-900 Watts of heat to disappate, the amps will eventually set fire.


Although a combined hi-fi/BBQ/Heavy Metal Concert Pyrotechnic stage show has a certain fascination, product longevity may suffer.

Other than that, good speakers. Need the Mana stands though.


Oh yeah, surely it what the quality of the first watt that counts?

Class A up to 2/3 of maximum output, sorry.

I still doubt it if is Class A beyond about 5 Watts, maybe less.

Doesn't actually matter that much. I guess the point is, if it sounds good it is good. I wouldn't really try to justify the purchase of an amp on power output or Class of operation. That's Krell territory.

Arthur has 'PMS' Briks of a fairly early vintage. Conversion to passive isn't a design option, although of course anything is possible.

Have you ever heard active Isobariks?

And why recommend a £6000 amp when a s/h six-pack can be had for substantially less and Arthur already has the crossover?

Paul

Definitive evidence of deafness?

I've been using Naim Tri-amp (3x250's) system to drive Linn isobariks for around 12yrs now. The system has never failed to impress, and i would say that this would be the route to take, rather than the six pack. Improvements to the front end first being more beneficial than the six 135's.

Goood luck!

James,

I don't want to worry you, but you're beginning to sound like Mr. Pig...

James

You are sounding like Pig.......look what happened to him.

I've heard the POG system. And I have Aktiv Isobariks.

So it must be me that's deaf? Hand me the Q-Tips!

Crikey, a man of your means bunkrupted by standard Class A/B amps with bugger all current drain. Never!

I'll take the speakers. You can keep that CD player.....

On a democratic count of those who have heard the Pog system, I'm afraid to break it Paul, but you are unfortunately deaf.

How many of your caucus have heard my Briks?

Or perhaps one of those sensitive and delicate souls who "don't want all that from a Hi FI" and dislike live bands.

The 'Briks are staying' clincher (and this was when they were passive) was 'Hendrix in the West' sounding rather a lot like a live band. And very loud.

I've no desire to get onto an indefinite upgrading ladder, or into a debate about the 'Mana Effect', save that it appears to induce a proper attitude to music. And that was what I most liked about the Pog house.

Anybody who wants to criticise my system (or my record collection...) is welcome. Email in profile!

Paul

Seems that I'm deaf either. Listen to briks in various setups. Active, passive, older and newer version with different drivers but never ever got that what Pog's and my system can do.

Activating speakers isnt necessarily the last answer to get the best out of a system.

Well Paul and the towers are growing

See you

ah..... now I know who you are. Hey you should update your profile.

Send it over I'll upgrade the picutre.
