    VAT is akin to a sales tax where an incremental fee is charged at every step of handling, it can be quite a bit. BUT, is removed on anything exported from a VAT country.

    The other taxes are more typical of international trade but shouldn't scare anyone off. For small items that can be sent via post, you can typically avoid any of them.

    I was importing cases of Tangband drives long before anyone here had hear about them, the fees to DHL were inconsequential and the boxes were quite large.

    For smaller stuff, I routinely get stuff posted from all over the world, no fees whatsoever other than postage.

    So if you find small components you like, try to get the seller to ship them via their post office, is my advise.

      ​Mom used to live in Germany. When we went and bought a few bigger ticket items, we could fill out a few forms and get a REFUND for the VAT! Philthien wins!

      ​Have Fun! Mark

        I just have to quote this again it is so good! "a DAC that has a high voltage out." What the heck are you talking about? You do realize 1.23 volts is +4 dBu, home audio gear
        generally operates at -10 dBu and ONE volt will generally distort the crap out of it. "2:1 or 3:1 transformer", "to bump voltage up" These are step down transformers and a
        4:1 would be suitable for a tube output section. I think you might have voltage and impedance mixed up AND backwards. By saying you were doing away with the analog
        out you were replacing it with something else? That would make a little sense but you need to read up and get your hands dirty and learn some real world analog electronics.
        I would be happy to explain anything you like involving the subject matter.
        Guess xmax's age.

        My guess: 15. His grammar is passable. His trolling is good.

          . This the DAC chip we are talking about. And all cd players have analogue output stages used to bump up the RCA and XLR voltages. The trabsformers I am talking about are about 1 in.75: inch in diameter and 1 inch tall

            Maybe yhis will help. You do realize that lots of car audio , smartly, have gone to up to 9 volts output. Imost dac chips are in the low 1 range or less. Especially older units.

              Actually the DAC chip does not bump up anything it only does it's job, additional electronics are used to buffer and/or raise the amplitude and lower the impedance as well convert
              the signal to fully differential, transformers are used to lower both the signal voltage and output impedance, isolate the output as well as create a true balanced signal.
              Why don't you say exactly what you are doing with the output transformer? It's unlikely a trade secret.

              People give me the same type of **** around here because they have no idea what I am talking
              about. It is not the case with this thread, like I said and others stated earlier in the thread. The MIT and other high end cables have a filter, it's well known, anytime you see caps and chokes the intentions are to lower the amplitude of frequencies whether it is a notch or a shelf the end result is less of something (always high frequencies with these products).

                That probably would be a good idea in the harsh car audio land. Are we talking about car audio?

                  The reason for the higher voltage is for more noise rejection, not the venue in which it's used.

                    like Wolf said, higher voltage is always good regardless.

                      where do you get this stuff from. no, the DAC does not increase anything, that is why you have an analogue output stage. i told you what the transformers do, they allow you to get rid of active and other parts in the analogue output stage so you have a cleaner output signal, i said you could go balanced off of them, you do not lower a low voltage that is already low in an output stage, noise rejection..i can not make it any more simple. as far as having to have a analogue output, you are wrong again, there are numerous systems that run digital all the way through to the amp section now. as far as the MIT cables and the box, yes we all knew there was a filter in them, i have never seen anyone say exactly what was in the box though.

                        Exporting goods to the USA

                        Most goods exported to the States can be zero-rated for UK VAT purposes (that is, VAT does not need to be added), as long as documentary evidence of the export is kept. Any extra charges made for freight, shipping, postage or delivery are also zero-rated.
                        Even where VAT is not being charged, the net value of the sale must still be reported on the UK VAT return, in box 6. It should not be included on the EC Sales List, nor on an Intrastat return if the business is required to make one.
                        If the UK business accounts for VAT on the Flat Rate Scheme, it must include the value of the export in the turnover on which the Flat Rate VAT is paid. This may mean that the business is better off not being on the Flat Rate Scheme.

                        i do not know if the people in england producing the transformers just did not ship many to the states and were not setup for it, or probably just dealt more with the EU countries. on my billing statement was Flat Rate Fee, which he said was the VAT tax that had to be added in.

                          I would be happier if you did not. Most line level home audio signals operate with peak signal levels over a volt. Most power amps have a voltage gain of 20 to 50. One volt will not distort any decent line level audio transformer.

                              The point being, the term "high voltage output is misleading", again we were talking about a cd player and the conversation turned into 9V
