  1. The thing is, the input *is* electrical not electronic and yes I have worked with electronics as well. As far as "hearing what no one else can" is an absurd statement as both my son and I could hear the subtle difference. Interestingly, my son heard a difference and I had not told him what I had done at that stage. There were no measurements made other than with our own ears as the decision to hard wire was not done due to thoughts of better sound, just removing a possible issue. However, I have no more interest, can't be bothered and life is way too short in trying to convince your strongly held religious belief that it could not have made a difference.
  2. I work in the electrical industry for close to 40 years and have the qualifications to assess electrical gear and have done many such alterations. I know what I am doing. The fact remains, we have heard the difference, slight but audible and not just one person but two people who heard the before and after. So, having both heard a difference, you can go on all you like about how it *should* be to your expert qualifications, but it did work.
  3. So, no matter how bad the IEC connection is, there is no improvement whatsoever? I mean, why bother having a good connection in the first place? Sorry, this just doesn't hold water. You can think what you like.
  4. No, both my son and I could hear the difference. A less than perfect connection will have an adverse effect on the power delivery.
  5. And I mostly agree. My IEC plug was a little loose, see my response above.
  6. If it is out of warranty, then there should be no issue to get the input connector changed or hard wired. Get it done by a qualified tech and it will be ok. However, it is not rocket science to fit a captive lead. I did it and it is easy - having said that, I am qualified to do the work. Trash resale value? Hmm, that's a little over the top, especially if the work is carried out by a qualified tech. IEC cables are only provided so as the component can be sold the world over and a generic power cord with an IEC input can be used. Cheaper to use a generic IEC input to the component than to have hard wired cords to the component and provide different plug tops for particular regions. There is just no way for an component manufacturer to ascertain how many of each type of cord to apply to the component for every region, a production number nightmare! Better to have all components made the same and then provide a cheap cord to suit the region and thus remove the guesswork about how many to build with the appropriate power cord. So, a hard wired cord can only be of benefit to any second hand purchaser as it removes a possible sonic degradation source. As for sonic benefit, I think there is. My Plinius 9200 amp was sounding a little "thin" and I wondered why and when I started to look for possible causes I found my original IEC connection was a little loose and even buying a decent new cable did little to improve the tightness of the connection. I purchased the ISOTEX EV03 Initium Power Cable as it was the cheapest of the decent looking power cables on the market, had decent CSA and I thought would have a tighter fit, which it was, but did not really fix the looseness to my satisfaction. I then decided to hard wire the cable to the input of the amp and that was when I really noticed the difference. Better dynamics, tighter and more extended bass end and cleaner mids. Subtle, but it was there. Whatever the case, I have a much better input that removes a possible sonic degradation due to a probable loose fit cause.
  7. The best thing for me was to hard wire the mains lead to my Plinius 9200 amp rather than use an IEC input connector. That made quite a difference.
  8. I used to sell Ralph the enameled copper wire for his crossovers in the late 1980's and early to mid 1990's. I still sell the wire but very few make their own speakers here or crossovers for that matter. In fact, there is very little manufacturing of anything here!
  9. No, I didn't notice. I guess that's the worst thing about checking "new posts" without checking the forum type. However, I am of the generation that calls all recordings, "records".

  11. I too have a Plinius 9200 amp mated with a Marantz SA14 S1 SE SACD player and a pair of Orpheus Aurora 3.3 speakers (that I have used external crossovers) and like you, I have found it is not very forgiving of poorly recorded music. The system is very revealing or poorly recorded music but put some great recordings on, and wow, it really shines! So many recent recordings and most of the remasters seem to be dreadful, IMO.
  12. Relatively new to SN Forums. However, Photography is another passion of mine. Very nice, @gat474! Recent photo at the Medievil weekend at Penrith. Peregrine Falcon.
  13. I ended up hard wiring the Isotek EV03 cable to the amp and now there is no worries about any loose connections with the IEC plug at the amp end. I removed the IEC socket from the amp and replaced it with a piece of 3mm aluminium to cover the hole and used the screws that held the socket in place. I drilled an 18mm hole for a metal cable gland to hold the Isotek 03 cable in place and then connected the wires to the power switch on the amp. I also shortened the lead by about a foot. It is all as solid as a rock, looks like it came from the factory that way, except there is a green lead! Does it sound better? I think it does, but it could be just mind over matter. Whatever the case, it is one less connection to worry about.
  14. I don't think a multimeter will give an accurate reason as to what is going on, I just don't think there is enough of a resistance going on to be readable as we obviously have contact and the amp was still delivering. Also, as I said, we are talking about 240V, not low volts. I think we would be talking of differences in the micro ohms as the cable resistance would need to be taken into consideration from any reading. I ended up using the Isotek EV03 Intium power cables, which is the cheapest in their range. The only reason I purchased them was to get a tighter IEC fit at the amp end and that 2mm squared cable was twice the area of the original cable of 1mm squared. I had no delusions of exotic insulations and the way it is wound etc that would make a difference to the sound or noise. The new cable was purchased purely for a better contact at the IEC input and more csa is better (within reason) approach. There didn't seem to be any oxidisation when I looked at the input terminals of the amp itself, they looked clean. The terminals of the original cord looked fine as well. I also inserted and pulled out the old cable a few times to "clean the contacts" as well just in case. I then also ended up using a new IEC cable from another reasonably recently purchased product and it made no difference to the sound nor the tightness. I think internal connection of the cable are generally spot welded? That would have to be checked. However, internal connections inside the cable would need to be open to air to cause oxidisation and they are in a sealed plastic jacket so I doubt that would be an issue. Not only that, but I did use a new IEC cable that I didn't use on a recently purchased product and thus would not be old enough to have oxidisation occurring.
  15. So, if the new cable isn't giving tighter mains connection but I have superior sound - extra dynamics, bass, clarity sound stage etc - then it can only be the extra CSA of the cable, rather than the connection, that is giving me the better sound. However, I am not saying that it is not the better connection, nor am I saying it is not the larger CSA of the cable. I think there are a number of factors at play here, just do not dismiss them all or any out of hand. Also, I don't think you're giving me enough credit. I am not new to this and have been involved in the game for a long time and know my subject.
