  1. In praise of the ESP P06 DIY phono stage. G'day all, in another of my soldering induced wiring faults, I repaired bad wiring on my ESP P06 in here 'very' early this morning (but that is another story), and listening to it later for a while whilst doing other things, I was again reminded of what a fantastic sounding phono stage it is! I have a lot of phono stages, and a few of them are extraordinarily good but my humble DIY Elliott Sound Products DIY P06 is 'still' at the top of the pile! I have had a lot of fun building my various P06's over the years and even learned a fair bit along the way. In the end when I listen to a record with my P06, and I think 'that is the way a phono stage should sound'. Yep. Regards, Felix.
  2. How should a truly 'accurate' phono stage really 'sound'? G'day all, I have probably asked this general question before but it is worth asking again, because the realities of the RIAA playback curve will inevitably mean that 'in the real world' anyway, some deviation from the ideal, and I have personally confirmed that even 'slight' RIAA variations are indeed quite audible. So that begs the question of whether some deviation is 'preferable' in the sonic/musical sense? I think very possibly! I have often commented how my Bruce Heran single op amp phono stages, 'sound so good', well I strongly suspect that subtle RIAA variations are most likely the reason so the differential question is then, is true accuracy sonically preferable, if nothing else? My recently constructed 'hifisonix' design is very well designed and has a very accurate and linear RIAA playback response curve, so how does it sound? In a word 'neutral', but definitely not euphonic. Is it my best sounding? To be honest, I'm not sure, and 'therein lies the rub', as they say in the classics. Regards, Felix.
  3. G'day all, smoke alarms do worry me actually. Years ago Wormalds used to install ones in Government premises and the like using rather high activity Radium 226 and were very radioactive, and in my opinion not safe. These days smoke alarms for sale tend to use an Americium isotope which is safer but is still a potent alpha particle/ gamma ray ionisation radioactive source. The 'optical' smoke detectors are now more recommended by authorities like ARPANSA. Regards, Felix.
  4. G'day all, such things were very popular in many household items in past years. At least the zerostat uses a non radioactive piezoelectric approach to static removal and mine works fine. This is a interesting website. https://www.orau.org/ptp/collection/consumer products/consumer.htm Regards, Felix.
  5. 'The Sweet' G'day all, I must be getting old! I've just spent a bit of time this morning playing my old worn copy of the Sweet Singles Album and although quite worn, it still sounds fantastic to me. They were a great band and their music was fantastic and just begged to be played 'loud'. Sadly they lived the rock lifestyle to the full, and sadly payed the ultimate price, but music like that makes me glad that I lived my adolescence through much of the 70's. It was a wild, but fantastic time with hard rocking groups like The Sweet. My heartfelt thanks to you all! Regards, Felix.
  6. G'day andyr, I only started using them because Rod Elliott starting putting provision for them on some of his project boards, and I was initially attracted by their convenience. However I now know better! Regards, Felix.
  7. G'day mate, no these things. You can buy them in two way and three versions. I am starting to hate them! Regards, Felix.
  8. Bloody 'connectors'. G'day all, a bit of a vent! More and more in electronics generally we see 'connectors' of various types used and that's fine however connectors are fine if they are left undisturbed after being installed, however if they tend to be plugged and unplugged as I often do with my own DIY gear, they rapidly become a royal PITA! I've just replaced the power three way connectors and hard wired (soldered) the wires into the circuit board and thrown away those damned connectors which were always going intermittent and giving trouble! 'Connectors' are a bit like fuses....they are useful, but they can be real PITA's as I've found personally. Regards, Felix.
  9. G'day all, yep my sentiments exactly dwbasement Regards, Felix.
  10. G'day all. I was just thinking of years ago when those 'soft/antistatic record cleaning cloths', were a part of every record collector and player. These days carbon fibre brushes seem to have replaced them, but I can see them as useful and probably 'better' than the ubiquitous carbon fibre brushes in some respects! Any comments? Regards, Felix.
  11. My favourite 'commercially' made phono stages. G'day all, I have already nominated two of my DIY and op amp based phono stages are my favourites, however as many of my phono stages are commercially made perhaps it would be worthwhile nominating favourites from those! Actually that choice is rather easy and perhaps this does say something about op amps vs discrete (transistor) circuitry because my favourites in this category just happen to be units based on discrete transistor circuitry utilising 'passive' RIAA equalisation. My two favourites are at number one, my Rothwell Audio 'Simplex' and very close behind my ANT Kora 3T SE all FET unit. Trying to differentiate op amp sound from transistor sound is 'difficult' and may be due to several factors however it is my feeling that op amps do contribute something that may not be desirable overall. Both of these fine discrete transistor designs have a certain 'free' and unstressed quality that somehow sounds 'right' to me. I realise that the approach used with passive EQ between two block stages can be problematic for various circuit reasons but both the 'Simplex' and the ANT perform perfectly in practice. Enough said! Regards, Felix.
  12. When ones 'ears' don't agree with 'praising' reviews. G'day all, this is an interesting one. Of the many phono stages that I own, the Schiit 'Mani' is one of them and it is very highly regarded especially for the low price, and it is indeed a good phono stage. Quite a few of the online reviews are unbelievingly praising of this phono stage, so last night I plugged mine in and had a good hard listen, and to be honest compared to many of my others, it rates about a '5' on a scale of 10. It just doesn't push all of the right buttons with me. To elaborate, to my ears, it sounds audibly 'hissy' at any gain setting, and even a little 'compressed' in its sonic delivery! Maybe I'm just used to the sound of my other fine phono stages, but having said that the 'Mani' has a sound all of its own, yet the praise one often reads about the 'Mani' indicates that quite a few think that it is without peer. As I said before I think that it is a good phono stage, but that is about all. Sorry. Regards, Felix.
  13. G'day mate, yes it is, but it is a bit of an 'accident' actually. Regards, Felix.
  14. Bad solder joints that happen over time. G'day all, an interesting day one might say! My DIY P06 in here developed a fault (a lost left channel) which was 'eventually' traced to a hairline crack on a circuit board track which was successfully repaired, and whilst I was working on it I noted many solder joints that looked cold, frosty and 'globular'....all faults waiting to happen, so I went over and resoldered as many of these joints as I could, and when all was reassembled and tested I was pleasantly surprised at how much better the phono stage sounded! Was my initial soldering that bad, or do these degraded solder joints invariably happen with time? I wonder? Any comments. Regards, Felix.
  15. G'day all, thanks for all comments. My turntable in here is a pretty basic Marantz TT1200CT and I suspect that it is running a few percent fast, and enough to be quite audible. Regards, Felix.
