Perrew,

I do not know if you use sarcasm in there but Lamm LP2 is not my bellowed phonostage. In fact I am one of the very few people whop do not like it at all. How much in what I do not like in Lamm LP2’s MM section come from the WE417 tubes? It is hard to say. I am not inclined to blame the tube just because a unit with it turned out did not perform up to my level of demands. The type of problem I hear from Lamm LP2 might come from anything. So, I do not necessary associate my bad LP2 experience with WE417. I feel that LCR is the key element in Alnic phonostage. Also, Alnic has one extra stage around E282F, so electronically it might be whatever you can imagine. Alnic also looks like parallels the output stages with WE417. Lamm with a single WE417 has 3.5K output impedance – remarkably high. Alnic shall have twice lover. Alnic said that it has 430R but it is most likely BS and I would trust to Lamm specification – he always very accurate with specification. Alnic might use output stage as some kind of follower but I doubt and the need some gain after the LCR. I am not a big fun to parallel tubes but it is what they do.

I looked at the H-3000 phonostage specification. It might be fun to run it with ET magnetics. The H-3000 according to Alnic has two stages of amplification – it is how it shell be. However, it has just 66dB gain not enough for most cases. Alnic used my 7721 for both stages, most likely first as pentode and second as triode. I did the same with 7788 in the first stage. It was if I am not mistaken and still remember 55DB from the first stage and 33db from the second stage, the 20dB was eaten by RIAA and I end up with 68dB of total gain…

Anyhow, the LCR correctors with good quality of LCR filters are fun. That DaVinci LCR phonostage from Switzerland shall be interesting as well, at list the early versions 10 year back, when they made it one by one to order. I afraid that nowadays, when they have publicity, market share and distribution chains DaVinci might do the mass-market crap as anybody else…
