resistor relay volume control preamp

[Brab]

I'm interested in the Topping L70 preamp. Are there other similar preamps with resistor relay based volume control (with remote) to consider preferably cheaper? thanks.

AFAIK, the L70 is the least expensive remote controlled Preamp with stepped volume control, that's currently available.

Gustard H16 is a bit cheaper but I would choose Topping L70 because it has better SINAD and better functionality.

Sabaj A10h can be used as a preamp.

Looks perfect, but can't find any availability.

A resistor relay volume control preamp adjusts audio volume by switching resistors with relays for precise control and minimal signal distortion

I have an A10H which I use as a preamp and it works well.

precision and channel balance and easy remote control yes.
Distortion is not really determined by this.

I thought most of the Schiit preamps used relay switched volume? No mentions?

At the end of the day, an ALPs motorized blue velvet (conductive plastics RK-27) is arguably a better choice.

I don't think I've ever had a failed one on my bench.

 

[solderdude]

me neither. have seen relays and relay drivers fail ...

arguably, calibrated attenuation, channel balance, accuracy goes to the relay thingies at the cost of PCB space and power consumptions as well as mechanical noises.

I totally agree. Just don't ever use switch cleaner on one. Ask me how I know...

You have to use the right kind that does not affect the plastic film.

A few years ago I've build this with great satisfaction:
