Preamp for a Line Magnetic i518?

I read up on both preamps mentioned. It seems as if the Micro ZOTL is primarily a headphone amp and only puts out 1W. Is this really enough output to serve as a preamp. I'm not really knowledgeable on in depth electrical issues. Also it actually has speaker inputs. I assume if I were to set up as a preamp I would continue to run my speakers from my LM.  The Shindo is of course beautiful as well but the price of the Micro ZOTL is attractive!

Any other preamp contenders?

The Micro ZOTL can be used solely as a preamp if desired.  I'd email gon member teajay  via the audiogon site. He did a full professional review ànd now owns one.

I’m also thinking a Shindo Preamp, in this range the Aurieges MM, with phono. You would be simplifying the system, but also some of the loading and gain options of your Chinook. If you want to explore this area, I would think Arizona Hi-Fi or Don Better to be good sources. Not sure if you have thought about an SUT, which may be another option to explore along with the Shindo. With the above suggestion, you would replace your Manley. If you prefer to keep it, there’s also the Aurieges L, line stage preamp.

Thanks all. I will email teajay. 

fjn04, there are two Aurieges listed now...one is an older version with 2 units (w/separate power unit) and the other a combined 1 unit. Do you, or anyone else, know if there are any sonic differences?  Not sure why Shindo went from original external power source to internal power later. 

ekimg,

Just curious, are you using the stock tubes in the 518ia or have you swapped them out; and if the latter what do you feel is missing that is casuing you to want to go with a separate preamp? I have the 518 and with the exception of the stock 845 swapped in NOS 5AR4, 6L6GCs and 5751s and find it pretty engaging as is. Thanks
