As usual Britain is usually the first with nearly every thing ,starting with the steam engine and gives it away to the World for nothing, WWW etc. No wonder we have one of the largest deficits that can never be eliminated whilst we stay in the EU.

Odd way of looking at it.

The problem in Britain is that while it has no shortage of very capable inventors it also has a corporate and political structure run by public school boys (for our american cousins those are very expensive fee-paying schools as opposed to free state schools) who have no clue about technology and thus fail to see potential long-term benefits. They fail to support and invest in those inventions.
Other countries (particularly Germany and Japan) tend to have corporations run by engineers who quite easily understand the benefits of investing in new technology and are not shy of investing.

Take for example jet engines and maglev trains. Both british inventions whose creators singularly failed to get any kind of UK investment.
There are many examples of this and the only exception I know of are Doc Martens boots which were a german invention.

Given that 80% of UK foreign trade is with other EU member states leaving the EU amounts to economical suicide. The only future the UK has outside the EU is guaranteed bankruptcy.

You promote the lies of all the Political TRAITORS The EU needs Britain more than we need the totally corrupt EU. We have a balance of payments deficit with them. Britain is the best European market for Germany & France our roads are full of German Panzers etc.etc.so why are we throwing away £55 million a day at European Corruption accounts never audited the Germans are laughing at the sheer stupidity of our FOUL, Government ,In the days of Elizabeth 1, Heath Cameroon, Clegg, Clarke, Hesseltine Red Ed Milliband Johnson and many others would have all been decapitated. We need ALL our laws made in Westminster not Brussels .

Why would they be laughing?

Germany pays twice as much into EU coffers than the UK.
Broken down per head Luxembourg, the Netherlands, Sweden, Denmark, Germany and Belgium pay more than Britain.

The importance of the UK as an export market to Germany is rapidly falling anyway. They are now joint 4th with Italy behind France, the USA and the Netherlands. Next year Germany will export more to China than the UK.
Britain on the other hand would lose its 2nd, 3rd, 4th, 5th, 6th, 7th, 8th and 10th largest export markets totalling around 60% of all UK exports.

Should the UK leave the EU 2.5 million EU citizens who are happy to be here will be replaced by 2.3 million pissed off britons who currently live elsewhere in the EU.

International corporations who are now conducting their european business from a UK base will have to move to another EU country and that includes large mass employers like Nissan and Toyota.

The only people who would benefit from Britain leaving the EU are bankers because the one way the UK could stay afloat economically for a little longer would be to loosen the already too loose financial regulations in an attempt to attract more business.

The scenario of the UK leaving the EU has no winners but while the EU will bounce back Britain won't. It amounts to economic suicide.

Caucasian Blackplate Industry Professional Posts: 8313 Location: Seattle Joined: June 18, 2004	I worked for a Jeff Rowland dealer in the late 90's till 2001, and I do not recall any models with a switch mode power supply (the new ones sure do though). Many, many components are powered will wall wart style power supplies, and many of those are switching supplies. I'm pretty sure the new NAD D3020 has a switch mode supply.

The earliest use of switch mode power supplies I know of was in 1979 in the 1st Berning preamp(which had other unique features) put out by Precedent Audio.

You do have to make sure the high frequencies the supplies work at don't work their way into the audio circuits. But the supply can be orders of magnitude smaller and yet still be electrically large. Filling up power supply caps at 70 KHz like Soulution does means you're refilling tons faster than at 60 Hz out of the wall, over a thousand time faster. And the power supply is the amp. What we think of as the amp is a variable valve. If the supply is not dead nuts stable and sags(and they do) the valve can be accurate and still not pass enough current.

This absolute nonsense Britain is still the largest EUROPEAN export market for German, French Italian goods, Germany does not have the large deficit that Britain has. These EU countries will still want to export to the UK if we leave the EU, sooner the better. The main problem is that many of the super rich especially Landowners are getting massive amounts of free money from the EU for set aside etc, including Cameroons relatives & Friends. It has been reported in the Press that the Queen gets £7 million a year from the EU. The EU,Overseas Aid , LARGE Welfare benefits to migrants which they send back to their Home Countries to build Houses , nonsensical Green policies are draining away money badly needed in the UK to stop even more austerity cuts, Wake Up .

The UK has NEVER been the largest european market for Germany, that has always been France.

The UK as an export market has shrunk over the last 10 years from 15% of all german exports to 10%, the same percentage as Italy. The Netherlands take just over 11% of german exports.
Over the same time period China as a market has grown from 1.5% to 9.5%.

The UK only takes 6.6% of french exports, less than Germany (15%), Belgium/Luxembourg (8.8%), Italy (7.1%) and the USA (6.9%).

The UK takes 4.7% of italian exports, less than Germany (12%), France (10%), USA (7.4%) and Switzerland (5.7%).

The UK receives 9.4% of dutch exports, less than Germany (20%) and Belgium/Luxembourg (17%).

Spain exports 6.2% of their goods to the UK, less than to France (15%), Germany (10%) and Portugal (7.1%).

So while some EU countries would lose between 5 and 10% of their export markets the UK would still lose 60%.
As a market place the UK is not nearly as important as you seem to believe.

One of the reasons Germany has a smaller deficit than the UK is because they did not give their banks free money like the british did. They gave their banks loans with conditions attached, like that as long as a bank owes money to the german government nobody in that bank can earn more than €750k pa including bonuses. The banks paid back their loans within 2 years.
Economically Germany exceeded pre-'08 crash output in 2011 without implementing austerity cuts while Britain is still not quite there yet. The cuts made by the UK slowed growth and extended the recession by at least 3 or 4 years.

On the other hand over the last 10 years the impact of european migrants to the UK has been a net benefit of £20billion to the UK economy. Migrants are substantially less likely to claim benefits of any kind than UK citizens.

Green policies are good for the economy. In Germany they added over 350 000 permanent and highly skilled jobs to the economy. But then again Germanys aim is to be independent of fossil fuels by 2050 while in the UK the politicians never seem to plan past the next election.

As for corruption: It is true that the UK ranks lower in the international corruption index than most other EU countries. But that is mostly because activities which would garner a prison sentences in those countries are perfectly legal in the UK, like large corporate or individual donations to political parties.

A couple of minutes on google and you could have found them yourself but you chose to believe the lies fed to you by UKIP.

Interesting that you would vote for a french banker and his german wife in the mistaken belief that it might be better for Britain.
I suppose the irony in that completely escapes you.

What makes you think that?
Is it because I agree with the Confederation of British Industry regarding EU membership?

As it happens I have no affiliation to any party.

When it comes to voting I go with WC Fields: "I have never voted for any party, only ever against."
In May I will vote against UKIP and their brain-dead claptrap as they seem to be hell bent on destroying the british economy for good.

My current power amp (SONY TA-N86B) uses originally a "PLPS" power supply (pulse mode power supply?) wich, problematic, has been replaced with a modern version. Works great, I don't hear any issue or "noise" or hash, even tho it powers horn speakers.
