Beethoven Violin Sonatas---favorites and recs


I am looking for some recommendations. My current set of the sonatas (Argerich/Kremer) is really very good from a performance point of view but suffers from the typical mediocre DG sound. I love the recordings in my car, but in the house they are pretty week and thin. It requires an effort. I’ve also ordered the Mutter set, but again, its DG. My favorite violinists are James Ehnes and Hillary Hahn, but they have not recorded these works, so I need some help here.
I’d like your favorite recordings of the works (individual sonatas or complete sets) regardless of vintage and also some recommendations of recent recordings featuring good performances with excellent sound. Thanks.

Goofyfoot, No, I have not. Is that a recommendation or a request for information?
I have that set and it's as fine as any I know but it's also a DG recording.
Also, the no longer active Andante label released a box set of wonderfully remastered historical performances of strictly the 'Spring' and 'Keutzer' sonatas. This set includes Kreisler, Milstein, Szigeti, Goldberg, Kulenkampf and Busch. Its a shame that the Andante label is now finito but their out of print collections can be found on ArkivMusic.com for a significant discount.
I like the Szyering/Rubinstein recordings--not sure if they did the whole cycle, but I love the ones I have.
The complete 3 disc CD set on Decca with Kremer/ Argerich
are wonderful with a spontaneous feel to them.
