My current (ageing) system is Bluesound Vault2, Chord Hugo1 DAC, Roksan Caspian M2, Spender D7.1. Would a new amplifier be a meaningful upgrade?
If it's anolog inputs that don't work anymore, I can't imagine it would be a very complex repair. Soundwise, don't expect huge (if any) improvements from newer amplifiers. A good amp from 15 years ago is still a good amp. A good amp from 35 years ago is still a good amp. The only major change in the last decades is the introduction of switched power supplies and Class D power amps. But they used a lot of time to catch up with Class A/B amps with linear power supplies. They are now almost as good.Could be upgrade-itis! Some of the inputs aren't working any more on the Roksan and I'm feeding the Hugo into the aux input rather than CD. My thinking was a new amp rather than costly repairs, but I do feel the speakers would benefit from a better amp. Budget £1500 -£1800. Thanks for the reply.
