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.

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?
Ekimg,
I believe that the Shindo Aurieges has fairly high gain. You "may" run into the issue of using the VC in only the lower setting (9 of clock range) or it could become too loud. Matt would likely know if that’s a potential concern. In most cases a good active preamplifier is an asset and will improve the sound quality IMO. Overall system gain is something that requires consideration.

Charles is right about the high gain. You can run the Shindo through the line input if that is the case and use the (I think) passive volume control on the Line Magnetic as a trim pot, like the trim pots on Shindo amplifiers.

You should also try the direct input. See which one you like best and which sounds best to you.
