LEAK: TL12s requiring better than Tannoy or vice-versa?

My musical taste covers most areas of music: Blues, World, Folk, Soul, Rock, Jazz; acoustic and amplified. I am a guitarist and listen to a lot of guitar of all sorts. My room has a suspended timber floor with rugs, is book lined on the speaker wall and about 11 by 13 feet. I would […]

ACCUPHASE / LUXMAN: Informed comments requested

  Accuphase (and current Luxman) amps all seem to me all be fur coat and no knickers – beautiful and lavishly specified with that legendary build and “feel,” but sounding very uninspiring compared to UK home grown amps like a Rega Elicit, LFD or Croft, let alone a Sugden….. ” Brilliant. Just brilliant. MORE OUR […]

Q&A: Can you hear a difference in quality between Spotify’s 320 kbps stream and TIDAL’s HiFi lossless audio stream?

DANIEL FALLMAN: Yes, absolutely. If you can’t hear the difference between say Spotify and Tidal’s FLAC streaming you might have either or all of these three problems — all of which have to do with the dynamics of the music: 1. Your equipment isn’t good enough. If you’re listening to your music through your iphone […]

SPOTIFY: Normalization vs dynamic range compression

Have you ever wondered what the ‘Set the same volume level for all tracks’ option in Spotify is really doing?  No probably not, but I have. Googling didn’t help to find an answer to this question because some people say that it works by normalization and others say that it works by reducing the dynamic […]

CARVER: Amp Modelling: Bob Carver & Transfer Function Amps

“I heard some guitar amp modelling the other day & was quite surprised at how it’s possible to cheaply create a convincing facsimile of a range of different classic amps from a single device. This brought back memories of the saga of Bob Carver and his Transfer Function Amps of the mid-80’s, so I did […]

CONVERSATIONS WITH COLIN / STEP DOWN CONVERTERS: Do they degrade the sound?

  Dear Colin, I recently saw a 240v integrated amp from the UK and was wondering if it is ok to use with a Step Down Converter? What are the pros and cons of using a step down device? Does it affect the sound and am I in jeopardy of blowing the transformer or ruining […]

CONVERSATIONS WITH COLIN: Do slow blow t2 250v fuses blow for no reason?

Hi Colin. Just had a crackle in a left channel (nothing you’ve built by the way), fade to nothing, then that stench of death. Took the lid off my Crimson mono (a simple oblong) and all looks healthy in fact like new, the only thing that’s gone is the fuse. Could it be a mains […]

DIGITAL: The thing about digital volume controls is …..

Paul McGowan writes: I struggled with how to write this because the subject’s rather complicated and in the end decided to keep it simple.  Heck, it’s Sunday after all and we’re supposed to be taking a day off. Yesterday we covered analog volume controls and how they, by virtue of adding something into the signal […]

PHASING: Is it really, really all about this?

I’ve just got a copy of the old “Hifi sound stereo test record” and on the phase tests it seems to indicate that my speakers are out of phase as the image doesn’t come from the centre on the in phase test but does on the out of phase test. I’ve checked all the cabling […]

STAX: Using a Japanese specification amp in the UK?

Hi While at the Bristol show last year I had the opportunity to quickly demo a Stax headphone + amplifier set-up (I cannot remember the actual model – the headphones had rectangular-shaped pads and looked like the current 207/307/407 models). I was impressed. I have experience with middle-tier dynamic headphones (AKG, Beyerdynamic, Grado) but what […]

CONVERSATIONS WITH COLIN: What really are computer grade parts?

Dear Colin, Computer grade parts? What are computer grade parts.. such as Computer grade power-supply caps? Are these type of parts an upgrade and/or better than audiophile grade parts? For example, I’ve heard some people say, “I’ve upgraded my power supply caps in my amp to computer grade caps”. I don’t think I’d want computer […]

The validity of Hi-fi tuning fuses

“Does anyone here have any impressions on the Hifi tuning fuses and how they possitively or negatively affected components in their system? According to some audio enthusiasts, installing premium grade fuses in preampss, amps, phono etc make a significant improvement in the overall sound. Any comments are most welcome since I’m considering this relatively inexpensive […]
