Dougd1015,
I have owned LS25 MKII (uses 2-6H30s), the VT-100 MKII (uses 6922 input tubes and voltage regulators), CD3 MKII (no tubes) and now own all ARC REF gear (CD7, REF3, REF110) that use 5-6H30s in the REF CD7 and 4-6H30s in the REF 110 with Wilson Sophia IIs. I am very familiar with REF 210s (no 6H30 tubes used) and with the LS-26 (2-6H30s used). I've also heard the BAT VK-300x with the 6H30 option on Wilson Sophia IIs. Net is that system matching is the ultimate answer. Interconnect cables, speakers, and components together yield the final sound of the system but you probably knew that. Some say that the 6h30 components sound a little "whiter", more neutral sound whereas the 6922 components are warmer more "bloomy" in the midrange. Maybe. Depends on what speakers are used and what front-end. If it were me putting together an ARC system from used components (a great idea if you ask me!) I would go CD-3 MKII, LS 25 MKII, VT-100 MKII. A couple of other recomendations: Kimber Select ICs and speaker cable (copper KS-1111, KS-3033) all for about $10K. What speakers are you going to use?
