Audio's Most Enduring Products.

Illuminati D60 digital cable.Famous and most favorite digital cable.Need say more.

The Sota Sapphire. I just sold a Series II with an Alphason arm to a new friend. It's at least 19 years old, has required no tweaking or repairs, and still sounds great. If I was going to get back into vinyl I'd buy another Sota in a New York minute.

I second the vote for the GFA-555II. As much progress as has been made in SS amps, you still need to spend a whole lot more that what a 555II sells for used to hear an appreciable improvement, IMHO.

But I'd also like to throw out the Thiel CS3.6. They are one of Thiel's longest running speakers, and the lack of a 3.7 on the market (yet!) indicates that they are having a difficult time improving on it (though I am sure that they will). It also falls into the camp of having to spend vastly more money on an equivalent product to hear any significant improvement. I have heard my 3.6's up against two sets of speakers in the $10-12k range, and the 3.6's held their own or bested them. Lastly, the 3.6's are a product that lets you hear, with intimate detail, the characteristics of your other gear. So, you can drive them with amps costing twice what the 3.6's sold for, and still hear all the nuances of those amps (or whatever other high dollar gear you might be auditioning).

Shure V15 Phono pickup. Decades after its introduction it is still near SOTA (at least for MM) and reasonably priced.

Cast my vote for the old-school Infinity IRS lineage: the Deltas, Gammas, Betas, and legondary Series V. In addition, the original (orignial...) Kapppa series just below them are worth mentioning here.

It was fun watching Infinity develop and hone thier products throughout the 1980s and into the 90s, before they were bought-out by Harmon International. Their marketing tag-line from that time has always stuck with me as I enjoy this hobby - "We get you back to what it's all about: Music."
