    Think as said earlier theres many different ways of getting there. Not every way suits everyone or there would only be one manufacturer. Sure Jez would insist it be him

    “Nothing discloses real character like the use of power. It is easy for the weak to be gentle. Most people can bear adversity. But if you wish to know what a man really is, give him power. This is the supreme test. It is the glory of Lincoln that, having almost absolute power, he never abused it, except on the side of mercy".

    “You see these dictators on their pedestals, surrounded by the bayonets of their soldiers and the truncheons of their police ... yet in their hearts there is unspoken fear. They are afraid of words and thoughts: words spoken abroad, thoughts stirring at home -- all the more powerful because forbidden -- terrify them. A little mouse of thought appears in the room, and even the mightiest potentates are thrown into panic.”

    If it's a quantum device, the mere act of listening to it will change the sound.

    That's my point.... Give it 10 years and it will be here.... Gain when a sensor merely looks at it...

    It's ok Marco, science (alchemy) was once hailed as witchcraft and look where we are now - the polar opposite view.

    As an update I've been listening all afternoon, Cohen Some like it Darker (holy crap what a voice), FSOL, Yello Toy, Touch, One Second.

    Two things, liquidity is back! This may be for two reasons, the new Cardas golden presence interconnect between Vida and Truth has burned in some, or the Truth has burned in some.

    That later option seems a little strange as with no components in the signal path surely nothing can change? But the maker and users say that it does improve with use though he doesn't understand why. I guess it might be to do with power supply. scratch.

    And the second thing... I've been using the Yello albums as a reference for electronica and have used them often this last week with the truth and heard many new things compared to the Slagles.

    Well, tonight there's even more! Newly defined leading edges, subtle infections in vocal backing tracks, extra texture.

    I remember a review (Salvatore) saying it had the power to surprise. Yes, it does.

    My journey is at an end (for linestage at any rate!)

    This week the Hashimito SUT arrives... What will that bring to the mix....

How can anyone? You might have a chance of knowing what a symphony orchestra sounds like, or a string quartet. But you probably don't know what the original acoustic sounded like in which it was recorded, or what microphones the sound engineer used etc. The idea of there being a true and only "original sound" is even more meaningless in the case of electronically produced music, since there is a strong argument for saying that it doesn't even have a sound until it has been processed through some kind of music playback equipment - and they all sound different, as we know! So statements to the effect that all forms of signal attenuation change the sound, except for the one that you are using, are always going to be highly contentious. How do you know, for example, that those harmonic overtones that were heard when you used pre-amp X were not meant to be there, rather than the empty space that you might experience when listening with "The Truth", or that that warmth and richness was not in fact how the choir actually sounded on that day, rather than the "tonally neutral" presentation you are getting with "The Truth". The answer is, you don't. You cannot really say that one piece of equipment is more faithful to the original signal than another (*). All you can say is that you prefer it with (or without) the harmonic overtones, or that you like (or don't like) the sound of the choir when it is rich and golden. To claim more is to make a whole raft of assumptions that in many cases could never be checked-out and verified. This is a point I have made in other threads in the past. No music reproduction system is going to sound like the "real thing". They simply produce a facsimile of a musical performance, and if you can find and put together a set-up that appeals to your ears as a music lover, then you are winning! Go for it, but don't kid yourself that it is "real".

    (*) Well, you can in a purely technical sense, if you subject both pieces of equipment to bench tests with oscilloscopes and what-have-you. But that is not what we are talking about here, and good measurements might not translate into enhanced listening pleasure anyway.

    I'm still trying to work out what the clever concept is. It looks like buffer-attenuator-buffer, which is very ordinary. Ok, the attenuator uses an LDR, but that isn't new. Ok, the buffers are video buffers, but that doesn't qualify as a clever concept for me.

    The Truth is active. And all active linestages will give less than unity gain if you turn the volume control down a bit.

    There's loads of stuff in the signal path - a buffer, an attenuator and another buffer. Each of those buffers will contain so many active devices that you would look at a circuit diagram of its internals like this


    It's a very big world and there are so many people making audio equipment that it's extremely difficult to stand out from the crowd and get any sales at all, so I understand if someone tries to create some mystique about their unique circuit. Just take it with a pinch of salt, particularly any ideas about having nothing in the signal path.

    With any luck this thread will have piqued somebody's interest enough to take a punt and in a month or so will be able to give their 'subjective' opinion. Then I won't feel so alone in my findings. I emailed the maker tonight and told him straight that after putting in another 7 hours listening today there was no f*cking way this was ever going back to him. I'm very very very happy right now and don't care what technology it uses, a rubber band and pixie dust, I don't care - it's just given me 7 hours of the most pleasurable listening I can remember.

    It's easy ... no more confusion / obfuscation please.

    Photocells have
    2 legs, because the light source an LED making up the other two legs is not integral with the photocell.
    There is no attempt at encapsulation removing interference ( other than the casework ) from outside light sources
    Little overview of their audio characteristics very much related to the led/ photocell distance having to be manually set
    Fail to have low resistance capability, hence require buffer circuits to function in an audio circuit.
    Typically find use in street lamps and checkout counters, but extraordinarily are used here in an apparent good sounding
    audio device.

    LDR's (also known as Audiohm - for the very reason you present ) have
    4 legs
    LDR's are encapsulated meaning they are impervious to outside light interference and human touch or chemical degredation over time
    LDR's also precisely define the light source LED distance to the resistive element
    LDR's have a audio frequency and audio characteristic optimised photocell
    LDR's have well tabulated audio performance characteristics including distortion measured
    with the best circuit the manufacturer could provide about 10 years ago, ( subsequently IMO, I have realised far better )
    resistance being from 40 ohms NSL32SR2( S)
    -60 ohms NSL32SR3 and in the other direction NSL32SR2 5 mega ohms, to 20 mega ohms NSL32SR3
    the NSL32SR2(S) similar to NSL32SR2

    Ed, what is the current you are running to the photocell anode ? and what is the LED forward voltage - colour
    As a peace offering, my own circuits use 7.5ma

    Cheers / Chris
