I would, of course, be more forthright when discussing what I felt were the plus or minus points of a friends system. They would be familiar with the system I have, the sound I like etc. I would know that my comments would have no effect on our ...

I think I get what you are saying. There have been many occasions where I've bitten my tongue when presented with someone's precious and expensive cacophony of noise. I often take a small pleasure in telling them that it's either incredible or u...

Hi Romy,Wouldn't the Audax PRO170 be a suitable driver to try or do you think it has too many weaknesses? I realise Audax are no longer operating but there must be thousands of these drivers out there. I always quite liked what it could do even if it...

From the Macondo to the Celestion SL600 !I cannot think of two speakers that could be more different in terms of design philosophy and (I imagine) the presentation of music.If you can get any noise out of the SL600's I'll be interested to hear what y...

I have a preference for making the power supply a certain way and using certain types of components. If I do that and am consistent about it, I can get better results from some of those old tubes than I can from the more recent types. But hearing one...

I'm sure there are many bad implementations of the 845 and 211. Almost all of the commercially available ones are pretty mediocre. However I have heard good examples of both so I know it can be done. I've yet to hear an impressive 6C33 amp so it...

Romy,If making a Tractrix Horn to cover between 100Hz & 1000Hz do you have to choose an Fc or mouth size that equates to 50 Hz? I've often read, and don't know if its true, that tractrix horns actually need to have their Fc an octave lower t...

Romy, Did you ever listen to a Class A amp made by Andy Rapapport which later became the Octave Research OR1? I never opened one up to look but I remember someone telling me (possibly salesman BS, I can't remember) about how much attention was paid i...

I would agree with you that Lamm's system of naming his products wouldn't appear to be helpful to anyone. They are all too alike. When I was involved in that side of the business, I would always have preferred to use names rather than numbers, ...

If you are a manufacturer with a range of products you have to export and sell to distributors all over the world (many of whom don't speak english), it is far easier to give your products numbers rather than names. It is also far easier for those di...

I had to dismantle a friends chuffing PM6A drivers the other day (only to find that the foam spider had disintegrated after 5 years, nice work Lowther) What was interesting, possibly, was the coating that Lowther seem to be applying to the voice coil...

Hi Romy,That looks very promising. I can't wait to hear your impressions once it has been 'trained' to work in Macondo.rgds,Guy...

Hi Romy,Can't you offload some of these 'off air' recordings to CDR as .wav files, free up some hard disk space and then bring them back when you need them?(370GB is rather alot though!)rgdsGuy...

Hi,I was really just wondering whether effectively almost doubling the rotating mass made any audible difference to the presentation. From your experience, it would seem not which suggests that the kinetic energy stored by one SX8000 platter is ...

|
Hi Romy,Did you notice any difference in the performance of records played on the SX8000 platter once the 5000 platter was running with it? Did the additional flywheel effect manifest itself in any way?best rgds,Guy...

Hi Romy,Have you made any further progress with this project yet?best rgds,Guy...

I have heard Lamm ML2's in a couple of different people's home systems. Did they know how to use them properly? Well either they didn't (quite possible) or the amplifiers simply lacked the virtues I would prefer.Tommy Horning is the guy who makes tho...

Romy,I have several power amplifiers each of which sounds different. I might enjoy some aspects of what one of them does but feel that it could do other things better. Another of the amplifiers might have different strengths and weaknesses. None of t...
|
|
When I get around to making these I shall make them as close as possible to your detailed design. I want them to be representative of what you are listening to so I can better understand the elements of playback you feel are important. There doesn't ...

Hi Romy,I haven't measured anything I was just looking at the data sheet for the valve. I was hoping someone could explain to me how a device with that much distortion could be any good. I am quite interested to build a pair of these amplifiers to se...

Hi Romy,Am I misunderstanding something about the 6C33C?I had a look at the operating point you recommend for this valve in your 'full range' Melquiades amplifier. The way you are using it seems to give almost 20% THD.Does this sound good or is it ju...

There is a guy here in the UK who is a retailer but who also manufactures loudspeakers called Living Voice. He has several customers in far flung parts of the world where the mains supply is even worse than Boston. With the help of a supplier of...

You both misunderstand my intentions. I do read what is on this site. I enjoy and appreciate the expertise of its contributors. It is an oasis of good principles, correct motivation and an absence of commercialism. All of these things are precious an...
|

So Bill Fitzmaurice and Wayne Parham are perceived by some as experts. So what? How does that impact on what you do? There are many less than competent amplifier designer/manufacturers around aswell. It will always be that way.When Dr Atk...

Why do you care what Robert Harley, TAS or the people from Magico have to say?Why does it matter whether the reputation of horn loaded loudspeakers gets sullied in some way by these people? No manufacturer that I know of does it properly anyway. The ...

Hi Jim,Your comments about the operating point of the input stage and the resulting even order distortions may help explain why, whenever I have listened to the 834, it has sounded like a syrupy euphonic mess. I can get the same effect by singin...

Sorry, I have a better understanding of the purpose of this exercise now.Are you making 2 new platters or is one to be the existing Micro Platter?Given that your RX 8000 appears to have a platter made of phosphor bronze (gunmetal) what is your s...
