I share your concern about portability of the Bolder/RWA upgrades, that is one major reason I chose to do the digital only upgrade to the SB3 (cheap at $150), use my own separate DAC (an MF Tri-vista 21), and spend the SB upgrade money on the Bolder PS, which should be portable to the new SB4, if and when one comes out (it is portable to the SB2 and 3).
As far as the tube buffer goes, see my post above about the Tri-Vista. Great, great DAC with the tubes in the output stage and with a killer regulated interal PS, without the hassle/expense/loss of signal and expense that may occur by having to add an extra set of RCA's. -- davehg ------------------------------------------------------------------------ davehg's Profile: http://forums.slimdevices.com/member.php?userid=2269 View this thread: http://forums.slimdevices.com/showthread.php?t=23741 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
