Recordings, Concerts and Audiophile Reviews
  1. Elekit’s TU8600 may not be the year’s most anticipated amp for every audio enthusiast, but if you know a few things about Elekit, DIY, and 300B SET amps, it might be yours. And mine. Well, the ‘bad’ news is that our review sample hasn’t arrived yet. The good news is that it will be here very soon – likely in the next week or two. Better still, the amp we receive will be a “rev.2″ or in other words, the same as the production version that should be available to the public by early autumn. Some minor adjustments were needed to bring the amp to Elekit’s standard of audible hum (none). As well, the trafo rack is being redesigned so that the optional Lundahl output transformers (which are heavy!) can be accommodated. The even better news is that we will also be receiving the Lundahl LL2770’s – so we”ll be reviewing this amp with both the stock Elekit trafos, as well as with the custom Lundahls. Similar to how Steve reviewed the TU8340. Remember, both of these trafos have a third winding for the headphone output. I’m not a headphone expert, but for me, no op-amp based headphone setup ever came [...]
  2. Dear WoS readers, I’m getting ready to launch another audio website. This one will be different; it’ll be based on user reviews and it’ll be focused on turntables, tonearms and cartridges. This will be a communal effort, and I’m currently looking for a few volunteers to help me build up the initial content before the site goes broadly public. If you have expertise with analog audiophile gear new or old (Garrard, Linn, Thorens, Oracle, Rega, VPI, Graham, SME, Technics, Ortofon, Koetsu, etc.), or if you just enjoy posting about audio and have some free time, please contact me. There’s lots to do. If you have a collection of photos or brochures I would also love to hear from you. Thanks in advance!   Noam Bronstein [email protected]    
  3. A Quick-shot, 3 Tube, 12AT7 Shootout by Steve Graham   A German tube, a Russian tube and an English tube walk in to a bar……     The 12AT7 is not the most commonly used preamp tube in audio.  That distinction probably falls to the 12AX7, especially when you add guitar amps to the mix.  So why do a 12AT7 (aka ECC81, CV4024) shootout?  Because the opportunity arose when I had the Elekit TU-8340VK push-pull power amp in my stereo den a while back.  (links 1, 2) The Elekit uses 12AT7’s for both voltage gain and phase splitting, two for each channel.  And I already had three quads -two NOS and one new production – of my own.  I wouldn’t have to beg, borrow and test the patience of the kind people who have loaned tubes unstintingly on previous occasions.  As these are tubes from my personal ‘inventory’, there’s no time pressure to return them or write the review. Why three quads you ask?  Spares for my DIY phono stage.  It’s not ready for prime time yet, so the Ellie amp would suffer yet more tube-change related trauma after the power tube shootout that I subjected her to.  Decent NOS 12at7’s are [...]
  4. Fluxion E&M is the work of Mr. Young Ahn, a Korean-born electrical engineer, who lives and works nearby me, in the rural farmlands outside Brantford, Ontario (Canada). Out here, ginseng has gradually replaced tobacco as the main crop, but it seems transistors have yet to replace vacuum tubes. Hallelujah. Mr. Ahn has been building and selling his amps for a while now, but I believe this is the first ‘industry review’. A more interesting gentleman you will rarely meet in this hobby. And I should clarify: not only does Mr. Ahn hand-build each amplifier, he also designs all his circuits, and even winds all his own transformers. Yes, all the power and output transformers are all wound in house on a winding machine, and Mr. Ahn says this allows him to pass on a savings to the buyer. The number of companies doing this nowadays can probably be counted on one hand. Fluxion amps are given their model designations in homage to notable contributors in the field of electronics. The AV-7 is named after Alessandro Volta, who invented the electric battery. This is a 12-watts-per-channel, single-ended design, using the Russian 6C33C-B power tube. This is the infamous triode tube that was unknown [...]
  5. Victor Kung of VKMusic.ca has given us the green light to share a very exciting announcement. The long-awaited replacement for Elekit’s 300B SET amp (which we loved to death) has arrived. Well, it’s almost here. The amp will make its’ North American debut at the LA Show next weekend (June 2-4). After that I will be receiving the prototype for a full review!! Availability on these shores is scheduled for late September. The following is the press release and some tasty photos. Enjoy.   VK Music announcement YOU asked for it. YOU got it!! We listened to your requests, and the highly-regarded ELEKIT designer, Mr. Fujita, has taken these requests into consideration. We are happy to present to you the release of the newly designed 300B amp (late September 2017). The new 300B amp has a lot of improvements over its predecessor (the TU-8300R). Here are a few of its new features/specs: Tube Set : 12Au7 X 2 + 12 AX7 X 1 + 300B X 2 Now compatible with low to high impedance headphones Frequency response (-3dB) : 10Hz – 80kHz Max. output (THD 10%) : 8.3W + 8.3W (input voltage : 250mV r.m.s) Residual noise : 42uV rms (IHF-A) Power consumption [...]
