People,
Was looking to add a couple of Rode mics (NT-1 or 1A) to my project studio; & then began to think about also moving up in preamp quality, as well.
In looking over two choices, the Focusrite ISA220 & the PreSonus MP20, the Noise Floor specs are a bit tough to compare, for me.
The MP20 has 3 specs:
Noise Floor @ Bus = -90.2dBu
Noise Floor @ Main Output = -96.4dBu
Noise Floor @ Channel Output = -88.2dBu @ +24dB gain
The ISA220's specs are:
123dB EIN w/ 50 ohm input resistance at 60dB of gain
THD: 0.0008%
(& I noticed no reference to EIN or THD w/ the PreSonus.)
A review in EM from 1999 (which compared the MP20 to a "well regarded British preamp"), gave very high marks to the PreSonus; & comparatively; stated that:
Does anyone have any comparative experience with these two manufacturers/products (& I understand the Focusrite has other capabilities)...(or would someone have another recommendation)?
&...What should I be looking for in terms of quality...how do the above specs compare...are Xformer based units better than Xsistor based units, etc., etc.?
Thanks very much,

So, my questions are:"the MP20 sounded nearly identical, with an ever-so-slightly brighter top end and not quite as much warmth in the low mids. Impressively, the MP20 was also quieter than the other famous preamp"
