Thanks for the response John. I do have a slight suspicion on the performance of MAP-1, but I'm going to give it benefit of doubt due to the lack of evidence. However I am looking at two channel tube preamps in case I need to replace McCormack. The preamps I'm considering are BAT, VTL, and Conrad Johnson. Do you have experience with any of them? Particularly I'm interested in VTL TL-5.5, C-J Premier 17LS2, C-J CT6, and BAT VK-31SE. I understand that there are two different ways HT bypass is done. I need a preamp capable of providing unity gain of selected source on the shared output, not the ones that provide separate set of HT bypass outputs. Comments appreciated.
Lean sound. What's the cause?
When I add McCormack MAP-1 to the chain the bass is noticeably weaker and leaner than without.
control:
Linn Unidisk SC -> Tara Labs RSC Air 2 Series 2 -> Levinson 335
with MAP-1:
Linn Unidisk SC -> Tara Labs RSC Ref Gen2 -> McCormack MAP-1 -> Tara Labs RSC Air 2 Series 2 -> Levinson 335
The power cord I'm using for MAP-1 is VH Audio Flavor 1.
What is he cause of the lean sound?
1. impedance mismatch between source and pre
2. impedance mismatch between pre and amp
3. Tara Labs Ref Gen2 sounds lean
4. power cord
5. ???
