NHB-458 monoblock power amplifier

[Mike Lavigne]

Does it have this space to stretch out , seems limited by the room .

it would be interesting to hear feedback on the difference between one pair and two pairs in terms of performance.

certainly a larger room has more upside, but also more difficult to control. it only took me 10 years to just understand how to deal with my large room; then another 2 years to actually execute my plan to make it work correctly. my previous smaller room was duck soup comparatively, although it had limited scale and authority and could be over driven. not my current room; it just goes and goes now.

Did you listen to these speakers? There is a pair being advertised since long locally at 1/6 retail price and no takers.

I have heard the Estelon Extreme speakers when they were here in London a number of years ago. The hosts and the owner and his daughters who work in the company were incredibly gracious and passionate about their company, designs and speakers. i had a lot of respect for their entire presentation, and of course for the distributor, as well.

Incredibly well controlled within their limits and was impressed by how 'tight' everything seemed to be delivered even across a fairly demand range/scale of music. For me, where i wished it had 'more' was all-out effortless ability to give big dynamics/power/fill a room (compared with the big Wilsons, Focal Grandes let alone the Arrakis, Genesis 1s, etc). No, I did not compared side by side, but i turned up the music for less then 3-5 seconds in a decent sized room but not enormous...and the speaker strained. I have done this test on big Wilsons...and certainly on the Arrakis, it was absolutely seamless, composed...just louder and effortlessly so.

If the speaker has been updated since (does it have a 2nd generation cone now?)...perhaps this has been solved.

There is so much to like about this speaker, I would hope this bit is resolveable. At this size, scale and price...i want to feel like i could crank it and the speaker would be unflappable.

I have heard them at Munich, you can adjust the height by remote control to suit your room. They played with Vitus masterpiece. I have heard the smaller ones, properly set up in London with Vitus. They have a good and open panel like soundstage, but have a sharp (bad) digital type texture to their sound. In the same room the Avalon sounded more natural, though more fuzzy and less open

I discovered the following upgrade information, which might be interesting for all happy owners of darTZeel gear:

The first time you can see all upgrades at a glance.

I just love how the Chinese do warp 9. Don't you Mike?



And with a matching tt.

go big.....or go home.....is what i say!!!!! Crazy Rich Asian's for sure.

i just hate to get my swerve on and run out of poop.

assuming those bass towers are passive, and that's why one might need 6 channels of 458/468 goodness?

That's nearly half million bucks of amplification right there. Herve does make more than say 20 pairs a year, so these guys have cornered the market by gobbling up 15% right there! LoL

That is the proper use of the Dartzeel preamplifier - it has three independent BNC outputs for three separate amplifiers. Users can specify filters for these channels to lower the IM distortion when used with passive speakers.
