Salas hotrodded blue DCB1 build

[VT67]

The Dale NS5's are also 20ppm, don't know about the Kiwame's. Not much information found about this particular spec.

I have a question about the relay. Is this Panasonic Low Signal Relays a good substitute for the Omron?

Regards

Kiwame are rebranded KOA SPR, you can find the datasheet easily.

BTW they're carbon film so you can expect a much higher one (350ppm).

I've tried Mills in that position and they sound good but they somewhat hide details.

I'm going to try Caddocks MP930 next week.

I'm looking for a bit fuller sound that's why i asked for opinion.

For fuller sound the hot rod resistors are not the most important components...

Very important are also the signal resistors and the 100uF caps.

Can somebody help me out with this please? Want to make sure that I order the correct part.

I use those. They work fine.

I am currently running at 400ma (i.e. with 5R resistors). DC output is around 1mv for both channels -- dead silence. Sounds really good too. Thanks Salas for making this possible and all the help from everyone.

Congrats Jay, it looks excellent, well done!

Mounted them some hours ago... wow!

In tha last months I've used a crossover MOX to recover from the closed and no much detail given by Mills, but those MOX had a bit of harsness that I couldn't manage to remove fiddling with other components...

The Caddocks are simply right: full and open, detailed, never harsh, gorgeous voices.

Soundstage wider and deeper too.

The best money I've spent on the DCB1!

Well, I was wrong... Caddocks give also a fuller sound...

What resistance did you use? They are pricy though.

Yes, they are (7.95$ each from PCX)... but not incredibly more than Mills (2.50$ each from PCX) that are widely used with the DCB1.

The sound difference is worth 3x price? IMHO absolutely yes...

At the end they're 10 bucks more... a couple of good quality beers, isn't it?
