Modding options

We offer this section for educational purposes only and we do not recommend any modifications to your audio. You can easily turn your new components into expensive paper weights and you will definitely void your warranty.

There is not much room within the chassis for extensive additions to the circuitry however, some components can be modified and upgraded. These amplifiers do not have many internal modification options for the end user but there is one we can see.

Connectors - You may want to upgrade the stock units to some higher end connectors. For those, that use speaker wire you might want to add 3 way binding posts. These types of connectors would allow much more connection options for various speaker cable types.

Final thoughts and Verdict

The combination of the Mass and the Big Joe IVs make an excellent desktop audio amplifier system with 100 watts of audio muscle! The Class D design topology produces excellent, crystal clear sound quality even at high volumes. The volume control is exceedingly clean and offers a very wide range that is quite precise. This system provided dead silent operation, no hiss or hum, just great sound pumping out.

If we did have a complaint it would be the price may be too high for some. Class D can be very cheap at lower power rating but when you start adding high wattage output then can get quite expensive. We would have preferred to see 3-way binding posts on the amplifiers instead of just the Banana jack outputs.

We would say that if you are looking for an excellent sounding desktop amplifier system to go with your new speakers, go and give the Mass, Big Joe IV, bundle a look and long listen. If you heard anything like what we heard you should be very impressed indeed.

If firestone keeps turning out components like this, they will have no troubles building a large following in the North American markets.

Until next time, this is Robscix in the Lab signing off and still rocking the Guru3D Audio Lab with the Mass and Big Joe IVs.

We have been working with many different S/Pdif based products in the Guru3D Audio Lab for quite awhile now so we are excited to have a look at the Bravo and use it for some testing. FSA also just released the second version of their popular Spitfire Digital to Analog Converter, known as the MKII version. So without any further delay, lets have a look at the Bravo Digital Processor and the Spitfire MKII Digital to Analog converter.
