No one is being any sort of a guru Marco. I always offer honest advice but when other people who clearly haven't grasped some of the concepts then appoint themselves as judge and jury, I will...

Thanks Grant.

As you're aware, I don't have to offer any justification (my information is sound) so I won't rise to the bait. There's always those on these forums waiting to creep out of the...

May I ask where that came from Geoff? The values look about right and I do have the values for the tappings should anyone require them.

Alas, that doesn't make it right, neither is it right!;) Ahhh, the perils of t'ut interweb :doh:

The explanation for the autoformers given there isn't strictly correct either. They were there to...

The magnet/motor assembly was different. The horn length is different. The Force factor (BL) is different, and the Le was slightly different (measured). The horn notch values will be different...

Yes, as previously mentioned Tony, there's a lot of difference...the two are just not interchangeable. The 315 has different T&S parameters, a different motor, different chassis, different voice...

It would seem safe to assume that there were minimal differences between the 1012 X/O used in the Mk2 end-of-run Cheviots (themselves using the 3128) and the 1020 time compensated X/O used in later...

The horn design changed a little since the RHR.

I understand that the reasons for dropping the TC circuit (not shown in the above schematic) was partly because it didn't work well (partially as...

The 3128 used a time compensated crossover for the ABF type motor, typically, the time compensated 1020 crossover, as used in the Balmoral. It is not the same as the earlier AlNiCo HPD crossover...

I am not envious that 1% have he same wealth as 99% of the population. Envy, jealousy, anger even, are all reactions best left out in the cold where they belong. My family is my wealth, and no-one...

Audible Inter-modulation distortion, and harmonic distortion come to that, cannot be caused by speaker cable connections to binding posts. You can have poor connections and audible improvements may...

Errr...the distortion claim does sound strange, especially as there is no physical mechanism for any "harmonic" or "intermodulation" distortion to occur. That is plain, unadulterated, pure ...

With respect, that article is hardly ground breaking news to any audio engineer and simply deals with reactance effects, and effects on unstable amp output circuits, and uses some very subjective...

Good post Martin and for the large part, I agree. However it is not true to say that there has never been any serious research, because there has, plenty of it. Way back, in fact, after the first...

Crikey chaps, lets pull on the reins a bit shall we?!


Nr 1. None of us actually know for sure what the problem is. We're just guessing for now until it is confirmed;

Nr2. There is nothing...

Bias settings sound a bit high. This can cause the arm to drift on queuing.

Fair points Andrew, and no offence meant to the previous poster. With the Nag carts that I use (currently the MP-500 but I have had the 150 here too), increased capacitance does tend to make them...

This sounds like a capacitance load issue to me. Nagaoka work best with as small a load capacitance as possible, preferably close to nothing bar the cable capacitance, so 100pF.

At 300pF, all...

I have some empathy with your viewpoint Marco.

I have lost count of the number of times that certain companies have "designed" things using appropriate software...inappropriately. There is one...

Actually Marco, that's not the case at all.

If the right measurements are taken, and the size and design are right for the room, then an "accurate" 'speaker system should and will sound anything...

That's true Clive. Most power amps (at any rate) manage that today, but there's a lot that don't (especially valve amplifiers and many pre-amplifiers).

On the speaker front, you may be surprised...

In which case Clive, such speakers are NOT neutral but are simply "...bright and lacking in timbre".

"Neutral", "Accurate" are banded about by too many when they actually mean "bright". As...

Spot on Andrew, couldn't have put it better myself.

There is a lot of guff spouted about "studio monitor sound". Speakers are either well designed and have an accurate response, or they're not....

This is not quite correct Ken. Hooking up two loudspeakers to the same amplifier output puts both pairs in parallel, so the amplifier sees a load equivalent to the two sets of impedances in...

Exactly as Andrew has explained, this is why I would always specify the least reactive (but necessarily very well shielded cable) between SUT and phonostage, hence the Pluto (or Neptune) would both...
