Or is he FOS?

If not someone is.

The article states that there were over 100 variations. What is to say that those chosen by Sentec are the correct ones? What happens if I change tubes? To further extend the comment by doak I think more than one person is FOS. Another very small niche product for the gullible.Modest appearance and wall-wart power supply for $2500? What a total POS.

So, you've listened to it? Or does its "modest appearance" preclude that and reveal what you actually care about?

Looks like a Heathkit.

would it be a conflict of interest for you to enter a comment on this article?

I care about music. But I also believe we should receive good design for a very niche component that costs 2500 with a wallwart( I've built better regulated power supplies for only $60 -and that's in Canadian currency!). Would you consider a BMW M5 worth the money if it still performed as well but had an exterior that was designed by a poor designer with little imagination and was built like a box? Really, there are many priorities for the audiophile, and music lover. Is it a sin to ask for quality in the packaging as well as what's inside.Especially at the price point of the Entec?

Funny thing about the appearance/ styling of this product (since that seems to be the drift of the comments)-- when I saw the photo here I thought, immediately, wow, what a brilliant match for the gray Garrard 301 schedule one that I use!

Silvery hammerite enamel, tubes & bakelite knobs, even the plain-font lab-style black enamel faceplate badges are an exacting equivalent for the styling-- call it Coldwar Chic-- of the the Garrard 301.

{It may be surprising to think this, but penetrating blue leds + Cnc lasercut anodized AL slabs--- don't look too simpatico, next to a Garrard, an EMT, a Neumann deck.}

As to the power supply, generally the wallwart thing at this price level is a placeholder sort of thing, and the manufacturer offers another, more substantial & higher capacity outboard SE external supply as an option. In an enclosure matching the signalpath unit. So that may happen. Or not, who knows. All in all, I'd rather have a fat *external* wallwart, than a troublesome *internal* psu that is wedged-in to keep the product small.

I have nothing to do with this product, but it's worth stating some alternative viewpoints. And I would like to see a more elaborate followup to this.
