Post Subject: Words for the Lundahl amorphousPosted by Paul S on: 5/1/2007
Romy, my experience with the Lundahl amorphous core transformenrs is limited to my new phono stage, and I have have been dealing other issues enough that I am not ready to write much about it yet.
Still, there are qualities worth noting that I am fairly certain accrue to the amorphous core transformer, based both on my own experience with transformers in general and your recent observations.
One thing I noticed right away was a certain "image density", not unlike the ML2. This is not purely "topological", but almost certainly transformer-related, and I will get into reasons why later. Another interesting quality is absolutely unflappable dynamics, with no hint of saturation, and no harmonic shifting, compression, smearing, or thinning with speed, SPL or complexity; in other words, pretty much what you said.
I think Kevin Carter at K&K Audio, in North Carolina, represents Lundahl in the US, and he MAY have enough pull with them to get you what you want (if you don't call him up and insult him ;>}).
The North American S&B guy is John Chapman, the "transformer guy" at Bent Audio (where all problems are solved with transformers...), but I don't know if they do amorphous cores.
I never thought much about the idea of amorphous cores, but using them has been interesting enough so far to warrant continuing in that direction, I think, if only to further isolate and develop the qualities it presently appears they contribute.
Best regards,
