Grannyring most people want increased resolution while still keeping a degree of musicality.
The fact that you are comparing the La Voice to the MDT is kind of silly these are two very different dacs.
The build quality of the MDT is comunsurate with its much lower price point. The Aqua S2 to S3 upgrade is hardly over priced as many of the boards are changed and you are essentially rebuilding the product to move from S2 to S3.
The very fact that you can take an older dac the S2 and convert it to the lastest from the company means that a prospective buyer can get off the dac merry go round which is necessasitated by companies making non upgradable platforms.
So yes the Aqua dac is not a cheapier Chinese made non upgradable dac and you are paying for the dac’s superior construction and modularity, there is a strong likelyhood that the Aqua Dac owner has kept the same dac for many years or will keep the dac fro many years, as the dac can always be made current, the MDT will be relegated to the dust bin of history as a newer dac of the month from China will continue to gain users looking for a good sounding product at a much lower price point.
As per swapping a $100 to $400 dollar cap nobody is using a $400 cost cap in a $4k dac, you won’t find that cost cap in a $7k dac either, the reason is simple economics a $4kish dac must cost close to $1,000.00 to manufacturer, with any supply chain each leg of the chain adds cost and increases the final price to the consumer.
Most companies today believe in having a dealer base to enable prospective customers to be able to demo and receive proper service, this is much harder for a non USA based company hence the tried and trued dealer to consumer model works well and costs of manufactuer have to be balanced, the other thing is just because you put in a really expensive cap doesn’t necessarily mean you will get the benefit of a radically much more expensive part in that circuit.
We would agree with you that changing that one cap may make a huge difference we are just saying that it isn’t guaranteed.
Christian Angnelli of Aqua is a very talented engineer if you look at their parts specified they are using some very trick parts allready.
Just food for thought.
