DeHavilland UltraVerve or Shindo Aurieges?

It works with just about every tube amp I've ever come across. Most tube amps have a 100K ohm input impedance- no problem. Its just not a concern. The alternative to lower the output impedance of a tube pre is add more tubes or add an output transformer. More tubes is not an option sonically. Ouytput transformers are a great option but they cost.

The speakers (VMPS RM30M) are 4 ohms, the preamp (Shindo Aurieges) is 5K and the amp (NuForce 9SE V.2) is 45K. I'm afraid I am not good with impedance matching - does anyone know of any good books or sites that explain it well?

I've done a bit of reading already and I am now confused as to what gauge wire I should use for the interconnects (30 gauge not large enough?).

Does the above system match well enough impedance-wise?

I believe the guideline is that the impedance of the amp should be at least 10X the pre, so at 45k its on the borderline.... I believe that my Bedini amp is about 45K Ohms, and it does work with my Aurieges but YMMV. Maybe one of the experts can chime in....

However, if you match with a tube amp, like what Jonathan said impedance matching is less of a concern.

I use a DeHavilland Mercury II with my NuForce 9 SE V2 amps, and the combination is stunning. There's one for sale right now for $1995 on Audiogon.

Old thread, but I'd love to hear some new responses.

I just sold an Aurieges-L (dumbly) and now have an amp that would be compatible with its 5k ohm output impedance. (Decware Torii 3)

How would the dehavilland fair?
