After building my JE LABS Stereo SE2A3dx amp (see http://members.myactv.net/~je2a3/se300b.htm)
I am toying with the idea of building a preamp in order to improve the sound (if it is possible, I’m very happy with). I have seen a lot of schematics (too many) and I need advice to know which will match better with my amp. My source is an ARCAM CD73 CD player.
Possible preamps:
Salas’ 6V6 preamp
Hendram’s E182CC preamp (seems easy)
SY’s ECC88 Heretical preamp
TNT Preamble N 7586 preamp
Triode Dick Cleo 6 6N30P preamp
Libero’s 6H30 preamp
Pete Millet Low-mu preamp
Moebius 6AQ5 preamp
Andy Evans 10Y preamp
Poindexter 6T4 preamp
12b4A preamp (there are a lot)
Gavin
ArnoldC
Eliduttman
JDev
Guldbrandsen
Please, your advice

Hola lquintas,
From my experience driving amps with 6SN7 inputs, you should look at a DHT-based preamp - i.e. 26, 10Y, etc.
If you want to avoid the hassle of dealing with hum and microphonics, the go straight to the 27 tube. Here's a simple one:
27 IDHT Parafeed Preamplifier

I've personally used an Emotive Audio Erato with a 6SN7/45 Jeff Korneff amp and found the combination stunning.
Saludos y buena fortuna en el 2009,

An externally hosted image should be here but it was not working when we last tested it.

Senor,
The JE Labs schematic you linked shows a 3 stage integrated stereoblock amp. I suggest that you look at something other than a preamp to improve overall system performance.
What sort of volume attenuators are you using?
ARCAM CDPs have solid reputations, but you may be able to improve things in the analog buffer amp area. The DECWARE DIY ZKIT4 has the sort of small footprint needed for inside OEM enclosure CDP modifications.
