reiterate that my comments were related to the RIAA LCR of 600 ohms, and regarding this, I stressed the importance of pilots with plenty of signal. For a mortgage would not differeza, but for the musical performance, the difference is definitely there!

Similarly, considerations of the transformer NP206, did not enter the merits of the chosen topology, but were designed to emphasize that the cost of considerable RIAA LCR does not automatically make a higher yield to listen.

The NP-206 is better than many others in the management of large swing (30 Vrms) with substantial power (1.5 Wrms) and these are excellent to introduce the 600-ohm LCR RIAA. Although this unit is particularly well done, making it suitable for various uses is not optimized for weak signals. This makes no difference to a mortgage, instead of listening, especially when it comes to phono preamps, the difference is remarkable.
If we want the RIAA LCR squeeze the best we need to optimize the strategy so that each piece is favored in its strengths and weaknesses in aspects protected.

As evidence that there are no contradictions ... that I keep the group praised: "E810F triode conn. / NP206 / EQ600P RIAA," but change the strategy:



I fielded the same players with ... different roles.
Now each component is able to make better, according to the strengths described above.
When the signal swing, the transformer NP206 shoot tens of volts into the RIAA LCR, this, referring to 600 ohms at both upstream and downstream, is tetragonal at all, making the most of his chances.
The preamplifier output is 600 ohms to all intents and purposes, therefore no problem in driving transformer volume (which are not easy to drive for many phono).

The NP206 is now affected by important signals, both voltage and current, which makes irrelevant the less sensitivity than some irons in the Permalloy, allowing them to make better (however Permalloy transformers would not allow such high polarization and could not handle the same signal values \u200b\u200bdell'NP206).

not within the substance of what the current scheme has become the first stage, because it has no direct relation to the exploitation of LCR RIAA argument (although obviously the NC20 in that position seem exaggerated, but it works better dell'NP206 as more sensitive and, even more obviously, it would not hurt to use a triode transconductance gain enormously higher in a dell'EC8010).

speech apart is the validity in terms of musical performance, the same reasoning, however, gave himself that is talked about a device that already exists, should not be excessive difficulty of the move some links and see if it sounds better in the manner proposed or not.
