It is considerably more detailed than the 6N-P4030 with better “look-through” and high frequency extension. Both transient and ambience definition is improved. In the lower frequencies, it appears to be less weighty than the 6N-P4030. Closer comparisons actually reveal that the 7N-P4020III has deeper and tighter bass. However, the 6N-P4030 has a fuller mid-bass. Overall, t

Singapore Audiophiles do not really have much choice in installing audio grade UK wall outlets. Most make do by buying special US outlet faceplates that fit on our existing UK back boxes. This is of course in violation of local electrical codes. Furutech is one of the few manufacturers to offer a solution - at a price. They make a single or dual outlet UK receptacle, with a choice of gold or rhodium plating. The base metal of the contact points is pure copper and treated with Furutech's proprietary alpha process, which involves both cryogenic and demagnetization treatment. Featured here is the gold plated duplex model, FP-1363-D(G) Plain cardboard box (with a bit of sticker shock, according to Mrs. Audiophile) The plate is rigid and far less resonant than the stock outlet commonly used A close up of the terminals. No problem with the beefiest of cables A few pointers when installing these outlets. The faceplate is slightly longer than a standard socket. Measure carefully if install

DIY your own balanced interconnects with Mogami Neglex 2534 ! Neutrik XLR plugs, Mogami 2534 cable, paper cutter, Kester 44 solder and Teflon plumbers tape The Mogami Neglex 2534 is a flexible shielded star quad cable, i.e. separate shield and four individually insulated conductors. I have used this cable in both single ended and balanced applications, and this cable really shines in balanced form. Singapore readers can get this cable from Team 108 in Macpherson. You can have a look at their website for contact details and opening hours,   http://www.team108.com/ Once you have cut your cable to length, slide the rear plug housings on to the cable. I have lost count of the number of times I have soldered cables happily only to realise that I forgot the backshell ! Strip the cable and conductors, and twist the same coloured conductors together, i.e. form two conductors by twisting the clear cables together, and repeat with the blue cables. Bundle the shield wires together too. I would su

Here is a quick comparison of new 12AX7 tubes tried recently. All new tubes had at least 20 hours of burn in time on them. From left, RCA 5751, Sovtek LPS, Tungsol re-issue, Psvane, GE Triple Mica Black Plate 5751. My morning cup of coffee just happened to be there.  Tungsol re-issue (steel pin) Following from my review of Tungsol's 6SN7, a quick audition of its 12AX7 brother suggests that New Sensor is going for a particular house sound with Tungsol re-issues. Predictably, the 12AX7 sounds smoother, richer, with more bass emphasis compared to its EH cousins. The Tungsol has a creamy smooth midrange with a weighty and slightly rounded bass. The trade-off is comparatively less open highs. Brass instruments and the shimmer from ride cymbals have noticeably less rasp and decay. This also affects the retrieval of fine acoustic space. The lower register weight helps Piano notes though which have impact and good timbre.Resolution and dynamics are mediocre. BTW, like the Sovtek LPS, don&#
