I used to think that but now I feel that's shifted to the Emotiva BasX range

Emotiva BasX range

Hi Al ears

Thanks. I’ll have a look.

he is saying that the hagal amplifier is still gets distortion even with the sound engine at the end of the video so it’s basically a amplifier with very low distortion .

And what about your speaker cables acting like antennas that’s bad I thought good quality speaker cable was shield .

 

[insider9]

Thanks for sharing. Very interesting indeed. However I'd question distortion figures in new amps and how much they really matter. Ultimately even if the amp gives you the least distortion there's so much distortion you can hear from speakers and room interaction that ultimately it matters very little what amp is doing in terms of distortion. I've measured many Class A and AB amps now whether it's £4k or £200 amp audible distortion was determined by that of speakers and room. The only exception was Class D in the same scenario that showed lower distortion figures when measured in the same way. Although it sounded wrong to my ears.

I have suddenly become very interested in their Basx-PT100 / BasX A-300 pre-power combo.... all that for £928.... 'brill

And that's with 2x150 wpc, a decent 24/192kHz DAC, a MM/MC phono stage, subwoofer output, direct-coupled headphone amp and an FM tuner section..... ;-)

Now I would like so see Hegel try it.

The only thing I can think of that comes close is the Parasound Halo Integrated at more than three times the price.

That is a fabulous spec for the money! Karma AV seem to bring in several rather good, and underrated brands, like Goldenear speakers. And less underrated like Mark Levinson.

Very low distortion in the audible hf range

Normally I'd agree with you but when you listen to a Hegel you will hear whats different. Then other amps seem very noisy/grainy etc.

Kinda like going from controlled active back to flabby bass passive

And I've tested hi end naim, Cyrus, sudden and a few more.

Something is definitely different

Ok, all I'm saying is it may not be distortion related. It can be lack of negative feedback. Of course both these issues are addressed with Hegel design but there's something audibly different about no negative feedback designs.

Check eBay
A.set of ATC scm50asl cabinets with tweeters available

Wonder if it would be cost effective to fit the bass/midrange and 2 X amp packs
Probably not

Probably not

I'd say it's very worthwhile as long as they go for reasonable price. Drive units are not cheap but you'd be able to do amplification and digital crossover yourself.

For what they're worth you could do all including Linn Majik Exaktbox-i and have some money leftover. Would I have £10k for a project like this I'd definitely give it a go. I reckon they'd sound better than ATC made ones.

 

[newlash09]

The ATC's look exciting. And a good place to indulge in for Diy . Just to give a price perspective of what it may cost. Below is the Indian pricing for new PMC drivers for twenty 26. ( hand matched pairs of tweeters and mid range domes. Total 4 drivers ) - 1400 pounds.

May be the prices in UK are more reasonable. Considering that you are getting an excellent cabinet , will be a good place to start with for a active setup, that can gradually be built up as per available time.

That is a fabulous spec for the money! Karma AV seem to bring in several rather good, and underrated brands, like Goldenear speakers. And less underrated like Mark Levinson.

They do indeed seem to be bringing in a fair bit of American hifi, good for them because that's the only place in the UK that does Emotiva equipment.

As a brand, have always produced interesting components. They are aimed at the more affordable end of the price spectrum, and that seems to be the issue. The advantage of their affordability on the US market is somewhat lost by the time they arrive in the uk, shipping, vat and the rest bring the prices into line with a lot of mainstream and some uk branded product in an area that the british market is particularly strong and competitive.

That said, they offer a range of components that no uk manufacturer can match at the price, as Al points out, the BasX series can offer a genuine 150 wpc power amp for around £500, very competitive.

Be interesting to see what happens if the product becomes more available in the uk market.

Noticed the other day that Emotiva's range is also available through Audiovisual Online. I've purchased speakers from them in the past.

 

[drummerman]

Not sure if it's been mentioned but the review of the Emotiva duo is in the latest HifiChoice edition.

Great vfm if the review is to be believed. Don't like the 90's blue display.

This shows what can be done by making stuff in China and aggressive pricing.

As opposed to making stuff in China and still charging big bucks for it!

Electrocompanmiet have used a similar system for many years.

They have zero global feedback but have small amounts around individual amplifier gain blocks then the signal is moved forward to the next individual gain block that has it's own measurement and feedbaclk loop also they have separate transconductance and transresistance amplifier blocks .

The power supply is an FFT design which means not connecting the connection point of two windings of the power supply transformer directly to ground. Instead Electrocompaniet use one bridge and capacitor for each winding of the transformer and ground the bridge.

This keeps the earth and signal ground separate and results in quieter and improved performance.

The proof is in the hearing . *smile*

Something is definitely different

I feel I get a similar effect with valve amps. A grain-free, almost liquid quality.
