Thinking about upgrading, but wondering about diminishing returns


Hi folks,

I have mostly Conrad Johnson Gear-- LP260M SE mono blocks, with 8 kt120 tubes each.  These are SET amps that put out 270 wpc.  I have the Conrad Johnson  ET5 preamp, with a Telefunken 6922 tube, and a pair of EgglestonWorks Viginti speakers (their new take on the Andra's).  Phono stage is the Pass Labs XP-15.  For source material I have a Rega  RP10 with the Apheta2 cartridge, and the Oppo BDP105 (Modwright upgrades) CD player.  I have Audioquest Colorado interconnects (go easy here :) ) and Audioquest Oaks for speaker cable.  My listening room is 13 x 19, carpeted floor, drywall walls and ceiling (well insulated).  I set up with the equipment on the long wall, with me listening from the 13' side (with speakers in about 2 feet and about 8.5 feet apart).

I listen to a mix of vinyl and cd's; vinyl when I have several hours to listen quietly (and clean the records on the Clear Audio Matrix Pro Record Cleaning Machine).  I listen to CD's when I have less than an hour, and for when I work out.

I am thinking about upgrading a single component, probably my preamplifier, to a Conrad Johnson GAT2 or a Pass Labs XS preamp (solid state). My thought was that this will likely make the most improvement in soundstage, imaging and overall musicality.  A used GAT2 will be at least $14K and the Pass XS used is about $19K.   I am interested in hearing from those who have had experience with upgrades like this.  I am also wondering (as a middle class guy)  how close does this come to the law of diminishing returns?  Finally, is this the component you would upgrade, and if so, if you had a wide range of musical tastes-- mostly classical/full orchestra in vinyl and rock on CD's, which preamp would you select?

Please feel free to take a swipe at these questions, and also feel free to point out if you feel I should be asking different questions that will help increase my knowledge and advance the cause for others.

I am likely to go to an audio show sometime, but please don't suggest that I go and listen to the gear, as that's at least 200 - 400 miles, and I don't feel right about going to a brick and mortar store knowing that I will almost surely buy used.

Thanks in advance for whatever assistance you can provide.

@lous I'm sorry to hear that your Sota/Souther/Benz analog front end caused LPs to sound less than good overall.  My VPI TNTVI/SME IV modified/Benz Ruby3 on a Townsend Sink sounds fantastic.  Most LPs are quiet to as quiet as a CD.  Used LPs sound great despite the imperfections.  Record noise is in the background while the music is dynamic (I resell poor sounding/inferior performance recordings-to date 18,000 records have visited and left my music room).  I have great cabling and equipment which minimize extraneous noise relative to the music.  78s often sound very dynamic with great performances.  The Sugarcube digital pop and crackle remover works on any recording that has such and is easy and very effective as heard on many internet demos.  

I found that a dozen well placed PP Omega E-Mats to be a fantastic enhancer of music enjoyment; however, the new Gate appears to kill the need for a dozen's cost by providing 100X the effectiveness at $5K.  I was hoping that the E-Mats placement at equipment locations are substantial enhancements on their own and would add more than their cost to the Gate.  PPs manufacturer could better address this issue.

Nice system indeed. Conrad Johnson is a sonic match for Eggleston loudspeakers. Excellent suggestions as above. Consider cabling upgrades. How old is your Oppo player?  Hope you can make those changes this new year.

Happy Listening!
I’m in a similar gear setup as yours and one thing I’ve done that has vastly improved my enjoyment is getting a Tidal subscription and listening to the MQA titles there: wow. 

I wasn’t a big believer in MQA but hearing it has changed my mind. One great thing about Tidal is they have the standard CD-quality version as well, giving you the ability to A-B all the titles.

Anyway, just a thought; sometimes it’s nice to have your focus shift back to the music, instead of that “new gear” trap we all fall into.

Good luck!
Ill second GIK room treatments. I’m in the middle of treating my room. I just added GIK absorbers at first and second reflection points. WOW.  Sounds as if I upgraded my system instantly. My next move is corner bass traps then ceiling absorbers. Cable differences are much more apparent with my treatments. I just purchased new ZU Event power cables for my amp and pre. Background seems a little darker ( just a tad). Im not certain if I would notice without the treatments. 
Thanks everybody for the very helpful suggestions.

I have a call in to GIK and will see what they recommend and we can work out.

This process has been enlightening, fun and helpful.  

Thanks for all the insight and expertise.
