What's wrong with my system?


My admittedly budget, mid-fi system severely lacks base. And I don't know why.

It consists of:

Speakers: Tannoy Eyris DC1 bookshelf speakers on stands (they're the old version of the Tannoy Revolution Signature DC6 bookshelves with the dual concentric drivers)

Amp: Arcam A18 Amplifier
DAC: PS Audio Digital Link III DAC
Cables: Blue Jeans interconnects
Source: 256 bit rate AAC up to ALAC going to an Airport Express connected by optical to the DAC

The high end is great, voices sound amazing with the dual concentric drivers. But there's no base to speak of. And I know it's not the speakers because I once auditioned a modded Music Hall DAC which gave them a ton of low end (but eliminated the high end, which is why I didn't buy it).

Would the Arcam be the problem? I can't imagine it's the airport express or optical source to DAC because it's all digital until the DAC. And everybody loves the PS Audio DL III, so I can't see that being the problem, either.

Any ideas???

Can you try headphones or another set of speakers? How about connecting a sub-woofer to see if that produces bass? Or can you get some test tones and a db meter and see how the system measures?
The Arcam has a headphone jack. That is what I was suggesting. It goes through different amps and trying it would help understand if the 40 watt/channel was the issue. If there is plenty of bass through the headphones, then there is an issue with the output amps for the speakers. If they are equally muted in the bass, then it would be some other issue. Not definitive, but might help fill in part of the puzzle.

Given that the DRCT mode helped, what happens when you turn it off and adjust the bass and treble separately?
