if you had my system and $2,000 budgeted for an upgrade, where would you spend it?

This post may go a bit beyond analog, as it could encompass other parts of the system, but I am not interested in adding to the digital side of things, so here it is.

As far as I can tell, it seems like the places to spend that $2K would be on a better tonearm or perhaps a preamplifier upgrade.  I may be able to sell my Audio Research LS-25 and upgrade to ARC Ref 3.  As for the tonearm, I could sell the RB202 and get a Michell Tecnoarm, or step it up to an arm for about $1600 (are the Clearaudio arms nice?) and still have a little left over.

Can a tonearm upgrade make a significant sonic improvement?

I am not dying to spend money on an upgrade, and if the benefit of that $2K will be minuscule, I am happy to stay as I am for a while, my system sounds excellent.  But I am curious to know what the experienced people on this site would do the the $2K if they were in my shoes.

Where is the most improvement possible?
Thanks!
Mark

Looks like a great system!

While I have no specific suggestions regarding a $2K upgrade, I would recommend that you contact Wisdom Audio and ask them what the apparently unspecified input impedance of the SCS sub is.  Powered subs commonly have relatively low input impedances, and like many ARC preamps your LS-25 (which I assume is what you are driving the sub with) has a recommended minimum load impedance of 20K.

Also, as can be seen in the schematic for the LS-25 at arcdb.ws, its two XLR outputs are wired directly together, and its two RCA outputs are wired directly together and also to pin 2 of the XLR connectors.  Therefore if the input impedance of the sub is particularly low it could be having adverse sonic effects on the signals received by the main speakers as well as by the sub.

Room treatments, in my opinion should be considered at the top of every ones list. Unfortunately they are often neglected.

I would pocket the money until you have a desire to change the speakers or amps - very nice system and great art on the walls. May i ask who makes the cabinet?

I'd pick Technoarm and the rest would spend for music.
Technoarm has great wiring and definitely a big step up from RB202.

Thank you everyone, for the thoughtful responses so far!

Alpha, I agree, be happy with what I've got!  Beer and vinyl sounds like a good move!

Almarg, excellent insight. I called Wisdom and the impedance is 25k.  Do I have any reason for concern there?

Totem, I have been contemplating some DIY room treatments. Where would you begin?

thanks all,
Mark
