Many thanks, Romy; I was careful to put the old tube to one side, but it may be the new tube I put in was a defective one. I will explore with the tube from the other channel, which I know is fine. ...

Hi Romy,One my channels started emitting intermittent loud popping sounds, once every few minutes or so, and on inspection the current (set at 240mA) was in excess of 300 (my meters top out at 300). Assuming it is a tube problem I replaced the 6c33c,...

nearly there....add a peacock feather; a sword -- not mounted on the wall but casually in an umbrella stand beside some old walking sticks; a pair of small stone animals of some kind, ideally lions, in front of the fireplace; a head or a bust in bron...

There are two cities on earth where luxuriant variety -- along most dimensions of life -- is concentrated in one place, so any vacation is never more than a mile away. You just need to move to one of them......

As far as get_iplayer sees, there are three options flash standard (aac), flash low (presumably low quality aac), and wma 1. The options are set by adding a --types=x flag. All are lossy, so Guy's FM version may well be better....

Here is a guide for how to do it (mostly with success). 1. Acquire a UK IP address. 2. install "get_iplayer". 3. Find the PID for the BBC iplayer recording of interest by navigating to it within iplayer and reading off the alphanumeric code in the ur...

... is more interesting than Oxford, its fine civilisation less unattractively posterized by those more in awe of it than able to add to it; there is a purity in its otherworldly charm that makes Oxford feel cheaply meretricious by comparison. Shame...

No problem: acquiring the bbc iplayer streams is easy: just have no evolved FM recording. I'll send you an email with contact details in case you drop by. ...

I have the iplayer recording, 320kbps: if you'd like it let me know where to upload it, or if you want to drop by to pick it up: I am in Kensington Court, opposite the Royal Garden Hotel, which cannot be far from where you are staying. ...

Sadly I have no ADC set up, and the digital replay BBC3 offer is of course lossy, 128 kbps aac, I think, though the repeat broadcast should be ok. ...

"I wish the RAH had better accustics however..... "Yes, one reason I tend to listen to the Proms on Radio 3, despite living a stone's throw away. But at least you escaped the heat that was suffocating performances earlier in the summer....

A related point: isn't it odd that few are offering digitized renderings of rare and important pieces of vinyl commercially, perhaps played through a selection of parameter variations on some very high quality turntable? Given that quality vinyl play...

It is a more complex filter than that: the change in HF is just what we measure to detect it. Clinically, one never looks at transients, for example, though it is likely that the fundamental mechanism affects them too, for what you lose in the broade...

Zero phase filtering would not require a reference: the signal is just run through the filter in forward and reverse. But there is another filter to consider here, a physiological filter - presbyacusis - that means Yamamura's hearing threshold above ...

Having lived in London for many years, and having been to most of the best restaurants here I can confidently say the Michelin guide is as good a guide to restaurants as Stereophile magazine (say) is to audio components. ...

One striking thing is the dichotomisation of horn and non-horn, where really there is a continuity to examine, with interesting subtopologies such as tapped and synergy horns at the boundaries. I know these and other variations have been discussed he...

Though it may be better than actually being in the Albert Hall if the weather remains as it is: it is so unbearably hot in there live radio is currently the only way. ...

Romy, have you come to a conclusion about how to decide whether or not to change a tube in the Melquiades? How exactly does the glass change? Is it just the getter? What about the gas tubes where there is no getter? ...

|
Dynamic range matters, of course, but in using "low level" he critically conflates "low signal" with "low salience". The specific tone of a violin, say, is a relatively low salience feature (to those with little musical experience), determined by the...

Quest Components have cheap 0.68uF 950s in stock, which is what I am using (the SH50s I am driving need a high pass). I have not been able to find 2uF but have not tried Roman's idea of ringing up the factory: they should send you a couple for free w...

Surely it is to be exploited. How about a special audiophile version of the Siglo III, cryogenically treated so that the smoke it generates cancels out evil room resonance intermodulations. It could come with a handy phone app that calculates how man...

Sure, this gives us no measure of sound, for sound is not reducible to any parameter. But it will tell us which of these DACs recreates the waveform closest to the original, i.e. which leaves the fewest fingerprints on what it does. It will not neces...

Romy, have you ever considered trying with your three dacs the following experiment. You take a digital file and runit through each of the dacs. You then take the output and feed it back to your adc. You then take the resultant redigitized file and c...
|

I know there has been controversial discussion of this here, but anything upstream of a DAC, i.e. anything digital can have only one metric of quality: jitter (assuming bit perfection, which these days is assured). Unlike anything in the analogue dom...

is the compression driver problem not solved by using multiple drivers all feeding into the same, relatively large throat, eg four 2.5 inch drivers into a 5 inch throat? The idea is that sensitivity to reactance will be much less at lower excursions,...

So if a third party is going to build it, presumably off-site, the necessary cycle of evaluation and testing will either have to be carried out by the third party, or else made impracticable by having to travel for each revolution. So you would still...

What would be even nicer is a randomised switch together with a record of your preferences without knowledge of which mode the machine is in. That way you really know. But of course the company would be insane to do that as most people will probably ...

Hm...it may have been that the retailers I found who shipped internationally overcharged: I must say I did not investigate in detail, but I know others have got similarly unreasonable quotes. The sample request is a good idea: I will do that....
|
|
Thanks, Romy, online dealers charge something like $50 per piece, which is ridiculous, so the objection is less to the price than to the rip off. These are 3 quid each. ...
