  1. Good thing you stayed away from this Yamaha amp. You just dodged a bullet. There is something not quite right about this. This is a product that is touted to be "....started from the ground up to develop a musical design..", and yet, found to be it less than enthralling musically by the usual manufacturer-centric Stereophile reviewer. Its predecessor, the A-S3000 had gotten roughly similar adverse review by Absolute Sound magazine, so this is not merely a one-off put-down by a reviewer with esoteric sonic tastes, but underline a common departure from market sensibilities with its lineage. Meanwhile, measurement shows that it's amplifier design doesn't double its maximum power when the load impedance halves, which prompted John Atkinson to say that it shouldn't be used with loudspeakers with impedances that drop much below 4 ohms. And is the product designer even aware that the onboard MC phono stage invert absolute polarity??? Or was it done so intentionally? It certainly isn't the first time such absolute polarity inversion had occurred on Yamaha's premium products. The CD-S3000, CD-S2100, CD-S2000 were all found by Australian AVHUB magazine to invert absolute polarity as well.
  2. Looking for a PEQ app that can be applied to stored music (HDD) played through the phone. Anybody uses one that you can recommend? I'm hoping to use it to help pin point any offending frequency anomalies in the audio spectrum. Thanks
  3. I have both the Mercury boxset and the 5 45rpm mofi reissues. I'll say it again and again, the mofi are every bit inferior even though they are 45rpm. Their source lineage is dodgy. At best, they're only taken from us masters, you can hear it the way mark knofler's voice is reproduced, they are not in the same league as the UK original masters.
  4. Yamaha NS1000/NS5000 and Pass Labs (plus EMM Labs) make thoroughly wonderful combination
  5. The issue is that for both brands of machines mentioned, the silk thread that serves to elevate the vaccum nozzle above the vinyl surface and keep them from physically touching each other. all the sciences will tell you that fabrics material rubbing over rubber will induce the creation of static. in this case, the form of static created when the silk thread brushes over the vinyl surface can change the sound of the record in some ways: - dulling of the top octave frequencies - attenuation of overall dynamics - limiting bass extension and impact. The effect is temporary. you can immediately remove the adverse effects by splashing water over the vinyl surfaces and then removing the moisture by non-contact means - either by high speed air blowing on the vinyl surface, or high speed spinning of the vinyl record. tap water works better than distilled water in restoring vibrancy, dynamics, freq extension at either ends, and natural timbre to the sound of the record. i realise it will be difficult to imagine the sonic damages unless one has listened to and compared to the same record cleaned, and then dried with non-contact drying systems vs physical contact drying methods.
  6. go double run of cables to your speakers, but connect only from 1 pair of terminals at the cambridge amp. either A or B, but never A+B
  7. I had the PRC3. SOLD it. 3 issues I had with it 1. Water gets splashed all over the plinth. Always had to have a few tissue paper on hand to clean up while washing/drying was in progress. 2. Always had to watch it till the end and not let the nozzle stay too long over the centre label. 3. The action of the silk thread brushing over vinyl surfaces is a source of sound degradation. Induces a form of static that dulls the sound of the record. These days I use a fast spinner. Expel moisture efficiently, without supervision, and without degrading sound. You can experiment with different water to achieve static balance, and the sound you like (contact therapy)
  8. For some unknown reason the Yamaha NS-10M sounds muddy, slow, and lethargic when paired with their centennial series CX10000 and MX10000.
  9. Yes, it is true that the characteristics of tap water varies from country to country. And tissue paper materials are all over the map. But the conventional practice is using fabrics to wipe the optical disc dry, and that is where/when/how the problem of skewed imaging might had occurred in the first place. Many discs collectors who have the habit of buying pre-owned discs often find that sound imaging projected by their playback system are often skewed left. Sellers often would try to clean up their discs before putting them up for sale. Fabrics are mostly always used for this purpose. When fabrics materials are wiped over the surface of polycarbonate materials, some form of static are created. This has been observed to cause havoc with the data being read on optical disc readers, leading to a curious problem of imaging being skewed. Tissue paper in general, otoh, exhibit no such issue when used for this purpose. In my experience they even neutralise those residual static left behind by the action of wiping the disc with fabrics. Of course, different tissue paper exhibit different prowess of neutralisation. Tap water (running from the taps in Singapore and Hong Kong) have been found to be better than distilled water in aiding the static neutralisation process.
  10. Doesn't sound like you tried. There is a real purpose in using only tap water and tissue paper.
  11. Take a cd rinse it under running tap water for a minute. Wipe dry with tissue paper. Play this treated cd through your system
  12. Why don't you remove the dust cover while you're at it...?
  13. Do you wipe down all the carton boxes and hifi gears with alcohol when/if you receive them? Wash your hands too...
  14. Time-aligned speaker designs do have that sort of close-to-real life quality that draws the listener more intimately into the music. A more simplified, self contained system allows the user to less chance to introduce unlinearities into the system chain
  15. Its a box with a motor in the centre. The record is placed over the motor and spun at high speed to expel moisture from its surfaces. 3-4 minutes for record to dry completely. What I usually do is spray water on the record surfaces as it is being spun at high speed. Cleaning effectiveness is nearly as good as cavitation cleaning in my experience. I do not hear any improvement in cleanliness with ultrasonic cleaning. The ELP is ultra fussy as you know. The advantage is that with this spinner box I can use different type of water (or combination) to tailor the resultant sound to my preference. Buyers can order with acyclic cover to prevent moisture spilling.
