- The input selector buttons on the partnering PRE preamplifier can be tricky to use
- The down-firing status light colors may not match the manual's description
- Bass flabbiness was noted around 68-77Hz due to room node exacerbation
Comparisons (according to reviewers)
- Compared to monoblocks, the MTRS may not deliver as wide a soundstage or as breathtaking dynamic contrasts
- The partnering PRE preamplifier is as close to the proverbial 'straight wire with gain' as has been seen, heard and measured in HFN for many years
