Even the budget Crestas that my lad has in his room have much better imaging than certain studio favourites that I've compared them too. I have the original Crestas, dated 1970, which have been in the family since new and the Falcon BBC LS3/5a gold badge. I bought all the parts and cabinet from ...

KEF have made some great, legendary drivers, but their own speakers? no, not really.

With respect, Tony, that is simply not true and certainly not in April 2025 when they make some extraordinarily good speakers!

I think a company called IMF was one of the first, Yes, in 1978, for example, IMF had three transmission line monitors for sale, the TLS 50 II, TLS 80 II and Reference Professional Monitor Mk IV. The latter cost £803.68 per pair, inc Vat which works out at £4330 when inflation is taken into account. ...

Puget systems look good, I've used their site info and tools for some time, but as they are US based and I'm UK, I've never bought one of their PCs. They now make audio centred PCs:

I did a Google search for the advantages of oxygen free copper over standard copper cables and the first two pages of results were from audiophile cable companies. I saw nothing from an authoritative source. For normal audio cables OFC and silver are just marketing in my opinion. Many years ago I ...

I don't know the acoustic, either, but looking at online images, I think the organ may well be plenty loud enough I am unsure how you can determine that from photographs, but I am sure it does what it was built to do, that is, accompany a choir and lead a congregation. As a solo instrument, the ...

Also, can anyone explain the difference between these two products, and price points? Thanks for any insight. Telegartner connectors are very high quality, branded, connectors, whereas the CPC assemblies have generic BNC plugs. The Canford BBC spec cable is slightly less lossy at 1Ghz than RG58 ...

I believe the OPA604 is the recommended opamp upgrade for the Quad 405

Yes, that's what I used in my Quad 405 rebuild, currently £4.74 (inc VAT) from Mouser UK. I calculated that in today's prices, a 741 in 1968 cost the equivalent of about £20!

The LM301 also came out in 1968 and was the original input opamp in the Quad 405.

Forget snake oil.

Russell viper venom is far more interesting

John Siau, (director of engineering at Benchmark), sums it up very well:

I dont want something that feels awful to play and that I cant get real sounds out of A digital piano is easy to use because you turn it on, play, stop playing, turn it off: no messing about with computers/software, etc.. Most also have MIDI if you want to play with sampled piano, etc. and have ...

Look at Bach for instance when confronted with the new fangled Well Tempered Klavier, or was it the piano-forte - a keyboard that allowed dynamics! He went out and wrote 48 Preludes and Fugues ! Temperament is a fascinating area to study: is equal temperament always 'right'? For example, many large ...

If you read FAQ number 8, from ATC, it explains some of the issues:

Ooh - conductive adhesive copper foil is INDEED a most useful material to know about I have an unused free gift of Cir-kit, courtesy of the April 1969 edition of Practical Wireless, (I was a not very old schoolboy then). Cir-kit may be the original self-adhesive copper foil. There were instructions ...

Thanks for the links, the Benchmark white papers are always worth a read. Topping are making a name, one of the current 'disruptors' in the HiFi industry. Their £149 headphone amp, the L30 II has extraordinary specs and an ouput impedance of <0.1ohm! Worth buying to hear what it actually sounds like. ...

An excellent example of how to conduct an online survey. It contains several elements which I think should be included for all those wishing to post 'invitation to survey' requests. 1. evidence of ethical approval 2. participant information about the research 3. consent, either by form or implied as ...

Anyway, in Rod Elliott's HiFi headphone amp, (113), he says, "The use of a 120 Ohm output resistor is recommended, as this is supposed to be the standard source impedance for headphones. Many users have found that their 'phones perform better when driven from a low impedance source. The 'standard ...

Very interesting. Just looking at a few specs, the Audiolab 9000A has a headphone output impedance of 2.35ohms. Self was involved at Tag McLaren audio, which then reverted back to Audiolab, so perhaps his design thoughts on headphone amps continues. And the 'new' Quad 33 headphone impedance is also ...

The output impedance, headphones, of the Lynx Hilo 2 is 0.6 ohms and since the original Hilo has identical headphone specs, that too is likely to be similar to 0.6 ohms.

Direct from Cambridge Audio, at £169, a bit more than the 'Berry but it has an IEC socket, so no wall warts and would be a good buy. https://www.ebay.co.uk/itm/235474484589?itmmeta=01JHDBRCSQ2Z1ZH0Q6J5MYGCF6&hash=item36d35f7d6d%3Ag%3AkAUAAOSwEs1l8yxd&LH_All=1 Funnily enough, I am just boxing up a ...

Yes, all I need for this to work is a phono preamp The Creek OBH-8mk2 looks good, around £129. It has a 24v power supply, so will have plenty of headroom, (probably a pseudo symmetrical supply of some sort). And has had very good reviews. https://www.creekaudio.com/products/phono-pre-amplifiers/ohh- ...

instead of getting a new preamplifier I could use this L6 to solve a few issues, I could use the L6 as a preamp, to take our CD player, and a record deck via a phono preamp, Are you planning to drive a power amp directly from the 'Master' output of the L6? The specs state a maximum output of +15 ...

I use Carbon Copy Cloner for something similar, backing up to external SSDs and you can automate backups. It's an easy to use, but powerful, application.
