Passive Amplifier Question — Phono Passive to Linn Klout

[Lammie]

There are simple cheap converters to change the type of digital, if another small box isn't an issue.

I've seen some sorts of things like this:
Cheapo A-to-D

Surely these aren't great quality?

I've had a sniff around the ASR for AD converters, but most seem to be heavy duty types you would use for recording from microphones, etc—not for really for converting a line input from a phono stage or tape deck into a DAC.

I would be very wary of these ultra cheapo converters. Would they even be bit-perfect?

Your Kairn tales sound oh so very familiar. Especially with weird stuff after a power cut. Interesting note on the hiss with Linn, I always thought it was mains noise or interference or something. It was quite a pleasant surprise when the Topping went in and the hiss left.

Coincidentally I was actually on the Pro-Ject site a few moments ago and was eyeing off the AD Box (and also trying to make sense of the Pro-Ject site, good god what a mess). The AD Box is much cheaper than the Puffin (doesn't seem as fun though). The Puffin also has a Coax out, which happens to be the only vacant digital-in left on the D50s. It's 2.5 times the price of the Pro-Ject though. Hmm... maybe I can sell the Kairn *shifty eyes*.

Looking further into the AD Box, I think the volume control only affects the digital side, to avoid overload, so that might not be suitable. <https://www.henleyaudio.co.uk/products/AD-Box-S2-Phono?DepartmentIds=1&CategoryIds=72&BrandIds=2>

I'm not sure what you mean by 'bit-perfect' in the context of an ADC.

Sorry, I was referring to digital-to-digital (co-ax to optical, say), but put my reply in the wrong place.
