  1. I built my first px4 valve based amp in the 90s, a mate told me how much better the earlier versions of the valve sounded, I could not hear a differance in my system at the time. I then bought much better transformers over the years and built much better amps. (And speakers) The differences are now easily distinguished between them, but I think the biggest change is my listening skills. I have a few mates who have good listening skills, asking them to describe which aspects are not right with a system can be quite educational.
  2. my speakers sound very much the same regardless of the room they're played in. Note they are not bass reflex, but they do highlight whats feeding them very well. To me the amp is very much an important part of the replay chain, along with the dac to a lesser degree
  3. Both solid state and valve can be used as effects boxes, it depends on how they are designed My preference is for single ended amplifiers (both solid state and valve)
  4. I remember thinking like that when I first started building speakers back in the 90s.. building a speaker that works reasonably well in some areas is usually is a more realistic outcome
  5. But you don't clearly dont understand what linear is.. There are no transistors as linear as the original 1930s output triode valves.. I'm not talking about modern reproductions. You can run them without push pull or feedback that both reduce distortion at the cost of quality.
  6. Well actually shielded cables should be directional... for it to work it has to be grounded only at one end Correct grounding techniques are quite an art in my view
  7. The link below explaines how direction speaker work But it shows quite clearly that a couple of frequency in the inaudible range could make some 'noise' in the audible range.. https://www.explainthatstuff.com/directional-loudspeakers.html
  8. That is the issue in my view Slightly related I once had a couple of days with one of those light dependant resistor pre's. I had heard them on a couple of system and they did brighten the system slightly. Anyway I tried it in my system and what a shock. It was injecting a hash into the system, Nick Gorham had measured this particular pre and found it produced some distortion and my system resolved it very well. Scott lyngren was with me and we both laughed about it.. but it did make some systems sound 'better' I don't disagree that high frequency on your mains can affect a systems performance in the same way, me I would be looking as to why.. Its more lightly down to a good reason when you look into it A good fluke meter and a scope is of more value in my opinion and checks on all 3 wires.
  9. So it was a trick question I was being asked and replied to ?😮 Thanks for the advice about using your ears. The only thing I would add is that not all amps are the same inc sets, you seem to me to have only heard sets that do what you stated well.
  10. Dont forget the valves are just as important...😉
  11. A couple of tele valves in push pull is way off the type of valve amp I would consider building. so yes I can well believe they sound similar.
  12. I think I agree with that.. taking all forms of distortion into account.. Re demos ..especially the audio note low end kit..anything under new car money ?
  13. I agree.. for me I build amps and speakers and I want to understand what improves the performance of a hi fi system.. The design and the way the power supply reacts with an amplifier playing music is for me the key to a good amplifier.. I have loads of books on the subject but remember one paragraph measuring a 'normal' low distion solid state amplifier.. giving around 25% inter modulation distortion playing a set of complicated test tones through both channels at the same time.. I'll try and find it.. but I have a lot of books on the subject
  14. That's a shame you see it that way. Poor electronics Low transient response speakers sort of make music sound like hi fi and not close to a live music sound. The lack of cancellation in many set amps is the key. I was talking to Morgan Jones a few year ago about cancellation in push pull amps and he agreed it's a choice you make when going for a particular amplifier topology. Valve and solid-state.
