Smoke on the martini....

Never heard them play it like this but if you want to hear the current Deep Purple playing a lounge version of Smoke, follow this video and move about 5 mins in to hear the live performance, great stuff.

When albums ruled the world video

Fascinating video on the rise and fall of the LP as a medium for recorded sound, by the BBC. Worth watching all the way through.

Cartridge alignment joys

I've been trying out a couple of cartridge alignment gauges recently to celebrate the installation of an SME V on my table. The experience convinces me that those who find vinyl too fussy to deal with have good cause.

First off, in need of a new alignment protractor for the arm, I found that these are not  always readily available, and rather than buy one from the UK, I ended up dealing with the fine folks at Flat Earth Audio who were out of stock but told me they could get some from SME probably faster than I could. Deal done. At $18 shipped, this is never going to break the bank but given that you are only getting a piece of card with the devilishly clever SME design that allows alignment with single point adjustment, you cannot complain. However, from my perspective, there are still a couple of problems with this alignment tool.

On my SME 20, the centre hole on the gauge is larger than the spindle on my player, which was not a problem on my old 309 gauge. With the roomier hole, the placement of the gauge is never certain and either SME makes difference center hole sizes for different tables, or my older SME has an older sized spindle. The solution for this was careful placement of tape over both sides of the hole which I split carefully with an Exacto knife on two-diameter lines to allow me to center the gauge tightly on the spindle. Plenty of room for the anal-obsessive to worry that the diameter lines were not perfect but it worked well enough for me. Seems odd though that I am reduced to this.

Problem two is the degree of precision one can get using a single point that is determined by eyeballing the arm's alignment from above for placement within two lines representing the outline of the tapered tonearm. It is possible to move the arm slightly fore and aft while still getting the appearance of a good fit, which means that the stylus point also moves slightly without ever being certain that you have got it perfectly set. SME's literature suggests not to sweat it -- and that is probably the most appropriate advice here but surely they know who they are speaking to? Audiophiles live to sweat it! For the sane few, this is fine, but how many sane purchasers of multi-thousand dollar analog rigs are out there? So, ease of use is wonderful but the sense of precision one demands, especially with a table/arm combo as otherwise perfectly engineered as my SME 20/SME V, is lacking.

In search of alternatives (or could it be reassurance?) I have purchased the alignment gauge designed by AVID for SME arms from Analog Seduction in the UK whose price and service were very good. This arrived promptly and safely but you should be warned, the only instructions are etched onto the gauge. In form, it's a hard, mirror-like plastic, quarter-circle-ish in shape, which (incidentally) fits the spindle of my SME 20.2 perfectly. Good for several models of SME tonearm, it's almost impossible to photo clearly but this image from Avid will give you a good idea. Here are the instructions:

1. Point alignment guideline at tonearm pivot
2. Immobilise alignment tool
3. Align cartridge using one of the grid patterns
4. Without moving guide check correct alignment with other grid.

As one intrepid owner on an audio forum put it, it's easy from step 2 on, the problem is step 1. While the tool does allow you to sight down a guideline (unlabeled) toward the pivot point of your tonearm, if you can see it, the line does not go all the way, and in my experience, it can tolerate slight sighting errors which, if you can imagine the tool, means you would move it slightly left or right to get your fix. Of course, in so doing, move the position of the two etched alignment grids on the gauge. Small errors, perhaps, but variance in use that you'd obviously wish to avoid. In fairness, I've not heard to many complaints from other users, but then I've wondered how confident all of them are in their sighting?

I'd add another couple of potential problems here. When you go to step 3, do you lower the stylus onto the gauge or just above it? No instructions there but I lowered to the surface and noticed that if you really want to hit the target, minor movements become very important, all the more reason to get the tonearm pivot point sighting perfect, not just close. My solution was to run a taut thread along the line and across the top of the SME to try to ensure I hit the pivot point. It might get easier with practice but since the thread must rise above the tool to hit the upper pivot point on the SME, there is room for error here too. All this makes me think those expensive tools which contain an adjustable pivot to spindle element such as the Feickert, are not overkill; precision costs. Alternatively, stick with the SME paper gauge and 'don't sweat it'. More as I go.

Latest HIFI'Zine published

The March 2013 issue of HiFi'Zine is out this morning. It includes my review of the Legacy Studio HD monitors, plus interviews with the brains behind Vapor Audio and a new electrostatic panel for the DIY community, as well as a survey of mid-priced DACs by Oliver Masciarotte. As always, comments welcomed on all articles.

The Legacy's are packed up and ready to ship out (non-trivial when I have to haul the box to UPS myself) but I have some Absolute Fidelity cords in the rig, which are causing reactions in listeners, and a test of the PS Audio PowerBase is up next. Both, hopefully, in the June issue but for now, enjoy the March edition -- this is a labor of love, remember, the 'Zine is a truly volunteer effort.

Axpona -- the new RMAF?

I've not been to Axpona but I wish I could be there. Chicago is just a great location but I suppose once you get there for an audio show, location is not really a concern. Looks a little quieter than RMAF, which has got to be a plus for all but the dealers.  This video from Cor Dekker gives you some sense of the occasion:
