Lamm + Wadia. A Good match?

You will have to jumper the Wadia down big time, the Lamm's have high sensitivity so 1 volt or less gets full volume. The Wadia has way high volt output 4+volts. The Wadia's volume is done in the digital domain so you will be bit shaving by reducing the volume So that is why you have to jumper the output down. I am not sure if you can get the player down to 1 volt. This was how Wadia's up to the 861's worked, I can't speak for the 581 and newer models.

I had a lot of problems finding a preamp to drive my Lamm M1.1 because of this. Be-careful with your first connection.

Although Wadia's output settings on the 5 and 7 series are not stated in the manual, the 9 series is adjustable from 0.5 to 4 volts. I believe the 8 series was adjustable down to 0.25 volts. This should be sufficient to optimize the listening volume to over 80.

I have a Wadia 27ix connected to the Lamm L2 preamp and ML2 amps. I strongly concur with Jtinn's response. I originally used the direct connection, but on a recommendation I trialed the L2 and was surprised to find the L2 imparts a significant improvement over direct connection. I ended up purchasing the L2 and would not go back to direct connection.

I have had no issues with level matching as the 27ix has a broad range of output voltages available via internal dip switches.

IMO the Wadia and Lamm components mate very well together.

Rtn: thanks for the detailed spec so it definitely can match up based on that.
Bgn007: Using a premamp you don't have to worry about the jumpering as much because preamps are usually designed to take from 2volt to sometimes 10volts depending on the design. Plus you can jumper the wadia so that you get to use the sweetspot of the volume control of the preamp for adjustments range.

My recommendation is to go direct. The digital volume control is the best invention in audio. You have to set it up properly though. Pre-amps add color if you want it abut at the cost of resolution, timing and separation of instruments. That should be a dynamite set up run through the balanced outs. Good luck
