You cannot upgrade an SD B2. If you had a 500G B2 say then no problem about opening it up and swapping a bigger drive. You need to do Settings->Maintenance->Format HDD after if it’s not FAT32.

Neil, regarding digital room equalisation, is it a gimmick or does it have some application in domestic situations? I have heard these things in operation and I suppose that if you are prepared to spend any time experimenting and moving loudspeakers then it’s a good shortcut to a sort of middling performance. But by and […]
Q: Hi Mike. Some makers are extolling the virtue of seemingly unlimited amplifier power as a requirement for un-restricted system dynamics. Logical or merely smart marketing? A: Well I suppose it must depend on a number of things. Let’s take the things that it depends on. Sound pressure level – that you hear in your […]
Which is the better interconnect for home audio systems? Balanced XLR or unbalanced RCA? Paul voices his opinion and explains the differences between the two and their reason for existence.

Dear Colin, I have just fitted stock 2R7 Panasonic 0.1% metal film resistors to replace the “green” 2R2 wirewounds in series with the Millennium tweeters in my WD25Tex speakers. I expected a change ( a bit warmer) but was not prepared for such a drastic change – is this due to the 0,5R increase or […]

Turn the preamp level all the way up and use the DAC for volume control or the opposite? Turns out it all depends on what kind of preamp you have and how much attention was paid to its controls. Watch Now
This is a growing free directory. It’s only a directory and not a list of personal recommendations by me. Entry to this directory is entirely free. Any enginner specialising in the repair, rebuild or upgrade of vintage audiophile equipment can email me: hp@no-alibi.demon.co.uk with their link for inclusion here. Currently this site has in excess […]
Paul McGowan … Perhaps the single biggest reason to use a switch mode power supply (SMPS) on a power amplifier is that the output of a properly designed one is more like perfect DC than that of a conventional supply; and not just by a little bit. Conventional supplies switch back and fourth between plus […]
Hello Howard. Can you ask Colin please what is star earthing and does he / will he using it in his new designs? Ta muchly J.N Peterson {Colin} Dear J.N.Peterson star earthing should be used in all analog designs, that is a single zero or earth for every component on the circuit board and normally […]
Here’s one for you electric wizards to kick around. Whilst attending a recent hifi exhibition I was doing some power cord shopping. At one particular display I was being told by a very well known cable company representative, I’ll not mention the name so it doesn’t influence any responses, that the rule of thumb is […]
Paul McGowan writes: As we wound up our series on power supplies several of you mentioned what would seem to be the best power supply of them all: a battery. Indeed, a battery delivers perfect DC without any ripple or noise and is completely independent on the quality of the incoming AC. It would seem […]
Paul McGowan … Describing what we hear as having a texture is an interesting Audiophile term. What’s the texture of a violin or a tuba? Do these instruments even have a texture? Not really, this is yet another term used to describe something we hear in a manner that is easier for us to relate […]
We’ve all heard of film caps costing upwards of a hundred dollars and gold plated connectors more expensive than diamond rings. Why don’t manufacturers use them more? Are they simply hocukm or real? Watch Now
We all love our vinyl but let us not forget its many flaws. In particular, inner groove distortion. When vinyl spins the stylus follows in a spiral pattern. That spiral brings us ever closer to the center of the record where there is less and less room for modulation (think of the difference between the […]
Not many stereo systems can come close to reproducing the peak levels of live music. In fact, I’ll step out onto the ledge and say you’ve never heard a speaker that can even come close to live levels. I know that I haven’t. And, yet, we believe our systems get close to the sound of […]
Dear Colin, Zero autoformers; how to measure impedance please? I got a pair of Speltz zero autoformers recently but when I measure the total impedance, my multimeter sees only 0.4-0.6 ohm no matter what I do. It seems the multimeter could only read the DC resistance from the autoformer itself but not the total impedance […]
Dear Colin, Generally speaking, what is it that causes output transistors to blow? Do they tend to die a natural death? Bad drivers? Emitters? Problems with the rectifier circuit? Assuming there wasn’t shorted speaker wires or excessive moisture. The amp bias and the +/-77 voltage was fine before they blew. It happened on power up. […]
Hi Colin, Pls can you help me? Can I safely run a USA spec amp designed for 110v 60Hz in the UK on 240v 50Hz, with a step down transformer (but it will still be 50Hz). So many conflicting views across the web. I think a lot of people believe it can work ok the […]
The thread starts: As a public service… The following live albums are mastered with far less dynamic compression on DVD than on the corresponding CD for the same concert. (I have ripped the audio from the DVD and I listen to that now! They’re great!) Portishead, Roseland New York Jeff Beck, Performing this Week… Live […]
