Need advise on audio research


I just traded my Anthem pre2L for a Audio Research Ls7. Not having owned a arc I would like to know what others have used with either this pre of other arc gear?(tubes,amp,cables, etc) I still have the Anthem amp 1 with Meadowlark kestrals spkrs. I listen mainly to JAZZ. Thanks in advance.

They make great stuff, I used to have their solid state D130 amp. Most ARC pieces I've heard have a sweet midrange and sound very smooth. I'd look for cables elsewhere though.
I have the LS7 matched with the Aragon 8008 power amp and Thiel 3.6 speakers. This is a wonderful combination.
