Preamp for a Line Magnetic i518?

I am interested in adding a preamp to my system. Currently using a Line Magnetic 518 integrated 845 SET. I listen mostly to vinyl with a Chinook phono amp and VPI Prime turntable with Lyra Delos. Speakers are PSB Imagine T3. Any thoughts on adding a preamp and suggestions? Partial to tubes but let me know if there is any ss that would possibly be a better match? Budget approx $3500. I appreciate any/all advice....thanks.

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

Sorry- I haven't a clue, though I do find that 2 chassis version to be very interesting. Matt at Pitch Perfect will sometimes have a used one for sale as well. I ran my Monbrison in to an LM 211 IA without issue, but the 211 does not have a PRE IN like your 518. So in my case, I believe it may have been a compromise. I would reach out to users of Shindo pre and LM with PRE IN.... I would ask their opinion to see if the LM PRE IN allowed the Shindo to open up VC enough, and have small enough steps. I don't know the technical terms well enough to explain my last point, but hopefully you understand.

facten....yes I have rolled some tubes. Philips 5R4GYS rectifier, SED Winged C EL34s, and Psvane TII 12ax7. Haven't  changed out the 845s yet but would like to soon.  Not sure which ones so haven't done that yet.

I don't really feel (or know) anything is missing per se. I've had it set up like this for about a year and am very happy with my system as is overall. But can't help but wonder if I added a preamp could I be "happier."  Just thinking it could be even better. Most people I have talked with seem to think a compatible preamp would add some more dimension and be a positive addition.  What speakers are you using?

fjn04,

yes I keep in touch with Matt. I bought my LM 518ia from him as well as my LM 515 CD player. Great guy!

I have absolutely no lack of VC now. I listen pretty loud sometimes and never go past 11 o'clock. Do you think adding a preamp might affect the volume?
