![]() ![]() audiopro was rather self-effacing, and gave his general impressions of the system. The Turntable is Pro-ject X-tension 9.Īround the same time audiopro published his review in hifivision. Pic shows CDT-2 Transport used with DAC 2.1x. I actually once owned the AN-K loudspeaker that Vivek wished he had heard, but I will deal with that in the Overview - it'd not be entirely as he expected. There are even more similar tubes, like the PCL86/14GW8 (higher filament, used in the current Elekit TU-8100). The Japanese also love to make an elegant SE amp out of it (as in the older Elekit TU-870R and San Ei). ECL82 is also popularly used as a power regulator tube (as in my Shindo Monbrison). There were many lower-end vintage amps that used this (as well as the similar ECL86/6GW8, like in the iconic Rogers Cadet series). Space saving, as four of these can make an amp, with the 4 Triode sections used as splitter/driver (even simple phono) and the 4 Beams used as 2 push-pull pairs. On the ECL82/6BM8 Tube This tall Noval Tube combines a Beam power tube section with a short Triode section. ![]() The related nuvistor 6112 is used in many high-end Musical Fidelity Products (which are decent sounding). Others use them too, like Tim Paravicini in the Quad QC-24 Preamp. They are very durable that after all these years the units are still in function and failures are rare. ANUK used them widely in the original Zero and One series. On the 6111 These sub-minature double-triodes of military origin have to be directly soldered onto the circuit board but they are cheap, space-saving and sonically OK (no tube rolling!). The amp is similar in design but the DAC of the current Zero is a NOS design that uses the iconic TDA-1543 whereas the older one was a delta-sigma design. The current Zero's obviously are pivoted to a different crowd, the "entry high-end" aspirants rather than the more experienced "bargain hunters and adventurers". The originals were housed in plainer aluminum project boxes and significantly cheaper. It is the current Zero System, which differ in many ways from the original Zero components that I'd go over in the Overview (the AX2 appears to have been d/c'ed by ANUK). Some of our magazines will never say things like that! I must say, very honest review and Kudos to the webzine (which seems to have ceased operation)! Vivek had reservations about the CD Player and called over some of his friends for referencing. This is still top entry if you google ANUK Zero. In 2018, Vivek reviewed the ANUK Level Zero System for India's HiFi Today. This article starts with their Reviews and is followed by my Overview of ANUK - about time. Full system reviews are rarer and valuable. Given the hurdles Indian audiophiles face (like the difficulty of sourcing less popular brands, and the prohibitive import duties levied at individuals) it continues to amaze me how the community "gets so much done", a showcase of determination and stamina.Ĭoincidentally, in the not so distant past, Vivek and audiopro had both reviewed full ANUK systems. Perhaps the brute approach works better with less efficient speakers so let your ears decide.Review: Two Audio Note Systems (Levels Zero and Two)Īs I got to know them better, I learned that our Indian Trinity Vivek, Prem and audiopro are all prominent members of the Indian audio community. Nowadays I only listen to efficient speakers that only need 8 watts or less to produce concert hall SPLs and at the same time give delicacy and refinement. However high transconductance tubes were introduced at the dawn of the solid state era for radio frequency applications and using these tubes in an ultra low impedance input/driver stage in an SE amp sounds like a high end amp to my ears - been there, done that.so I am sticking with my Art Deco era tubes which were developed mainly for audio frequency applications. Technically speaking having a great amount of AC swing and low impedance driver looks ideal on paper. I tried a WE417/5842 2-stage design, cap and DC coupled, 3-stage with either a 76/37 or 6J5 or 1/2 6SN7 on the first stage and the second stage with a higher gm tube - 5687, 6BX7, 6BL7 and etc. I had a bread board amp at that time wherein I can change power transformers and experiment with various tubes and operating points as well as circuits. The greater efficiency and quality of the 755s showed that the classic JEL 300B circuit could be improved. Eventually I acquired a pair of Altec 755Cs, a little later the Altec 755As and mounted them on open baffles. During the initial development of the classic JEL 300B, I was still using Spendor LS3/5A speakers and its lack of efficiency was a limiting factor in my R&D. ![]()
