What SD CARD should I buy?

If you want an SD Card for your camera - these are the ones I use and recommend. 

I'd strongly recommend not to buy any SD cards off ebay - I've heard about too many issues with counterfeit cards - often sold on by unwitting resellers. My inbox regularly gets messages from people who bought a £150 camera then cheaped out and bought a £3 memory card on ebay - Then when it doesn't worth they blame the camera! It doesn't make any sense. Good memory is cheaper than it's ever been - see the links above.

A lot of HD cameras will not work properly with cards larger than 32GB (cards over 32GB are usually SDXC rather than the SDHC standard used by 32GB cards. SDXC cards use the ex-FAT system rather than FAT32 - in short they are a different standard). - so don't just buy the biggest card you can afford - read the specs in the manual to see what it accepts.


RECOMMENDED CARDS (for action cams - see dashcams below)

CLASS 10 UHS-1 CARDS (For HD Cameras)


U3 CARD (For 4K cameras)




The SD card in a dashcam is re-written over, more frequently than in other types of cameras. Some manufacturers void their guarantee if an SD card was used in a dashcam. So, no surprise, there are special High Endurance SD cards made just for's some.


VERY IMPORTANT. These links take you to the product, however Amazon have three different ways of selling. There's Amazon Direct - This means that you are only dealing with Amazon themselves, then there's other sellers that use Amazon's facilities - these show as Fulfilled By Amazon and finally there's Market Place sellers that advertise on Amazon, but operate independently.  I strongly recommend that you only use the first...the Amazon Direct - Sold By Amazon option. Even if it appears that you are paying a couple of £/$ more it is more than likely you are comparing the price of a real item against the price of a fake.

To give you an idea of the extent of the fake goods problem. In a 2016 survey by Apple - 90% of the 'Apple' chargers sold through Amazon - using the other the two methods..which includes the "Fulfilled by Amazon" option -  were found to be counterfeit....90%!

Out with the old and in with the new (amp)

I recently bought a new amplifier and it is the most expensive piece of HiFi equipment I've ever purchased. This was something for me rather than an oddity acquired just for the purpose of making a video. Whilst it's not as flashy or quirky as most of my HiFi equipment, I suspect it will outlast the other components and quite probably me as well. Some people wanted to see a video about it, so here it is.

Hi Mat,

Nice amp...great review as usual.

You mentioned you'd like a VU meter this might be right up your street its got a nice retro look - - not cheap but it does look like top quality.

There are some very items on that site.

Very cool, looks great!

As usual, I enjoyed the video. I have worked in hifi for almost 40 years, including some very high end gear. I had a laugh at the comment about audiophiles and tone controls. Well put. While I understand very well about the purist approach, bottom line is it is all about whatever makes you happy. If you enjoy dialing bass or treble up and down, or messing with an EQ, this is what is is all about.

I look forward to the next audio review.

Like Joe I also worked in the Hi Fi trade and had many prestigious customers at my London Marble arch shop.
People like John Entwistle, Vangelis and people from the BBC wanted tone controls, others didn't.
I used to have a comparator set up so customers could listen to a cheap 10 watt Sony Amp and compare it to a 200 watt Technics or Quad amplifier. Most could not tell the difference in sound quality.
The only ability of a powerful amplifier was it's ability to drive a difficult load presented by some of the bigger loud speakers.
A lovely well presented review and as I said to many of my customers, "Listen to the music and not the equipment"
