Tubed amps for WP7s

For my WP 6.0's, I'm using a single BAT VK75SE. Love it...

The ML 2.1's are the most musical amp I have ever owned. They are in a league of their own. At 93Db efficiency on the WP 7, the ML 2.1 will drive them easily. Bear in mind however that they are an SET amp and only 18 wpc. As a result if you are used to the bass slam from a big SS amp you won't find that with the Lamm. Instead however will be a very well defined bass. I doubt if I will ever buy another amp.

Another option to consider is Vladimir's hybrid M1.2 reference. Also fantastic

I will vote for the VTL 750s. And I use all the power, but it truly depends on your room size, music and prefered listening volume. The 750s aren't the last word in detail but they are the last word in musicality at loud volumes.

I have a wp7 and also own the hybrid ss/tube lamm 2.2 mono amplifiers.

I previously ran the wp7 with rowland 302 solid state stereo amplifier.

The Lamm's easily best the rowland when it comes to capturing the emotion and feeling of music. The lamm can also have as much bass slam as the rowland if you get cables that match amp/speaker combination well. I had my lamms with nordost valhalla and then switched to purist dominus interconnect between amp and speaker. The nordost did not provide enough down low bass with the lamm. The purist definitely does.

I have not tried the 1.2 lamm mono amps but have generally heard great things. My undestanding that you get a little more presence in vocals than on the 2.2. However, I have also heard that if you truly want to rock out to modern music that some have found it lacks all the punch you might want. The 1.2 and 2.2 are probably 2/3 the same amplifier. The 2.2 is 220 watts but 41 watts in class A. While the 1.2 is 110 watts but all class A.

So I would say try to listen to both but if you listen to a lot of rock than probably the 2.2. It never hurts to have extra power and the 2.2 is so damn good with vocals already.
