Masterclass IA-4 Integrated Amplifier

The IA-4 is Sugden's flagship and most popular integrated amplifier.  Weighing a substantial 20 kilos the IA-4 has a purposeful look and impressive build quality. Plenty of input and output facilities are on offer including a high quality phono stage. The class A power output circuit has been upgraded from the A21 series with a larger power supply and improved soothing and output capacitors. Gold plated circuit boards, full relay switching and a precision input selector switch offer further detailing. The pre-amplifier section of the IA-4 is a bespoke design, with surprising clarity and detail.  The most noticeable feature is the ability to create a large performance with depth and height on any type of music.

Testimonials

Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.

The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.

It’s now two weeks since I bought home my new system and I wanted to say thanks again for all your help, advice and guidance, not to mention cups of tea. I now have a system that meets all my requirements and sounds fantastic. Special thanks to Jon, who I hope is on the road to recovery from his operation and to Roger, who helped me finalise my choice. The Rega Saturn, Hegel H190V and Dali Rubicon 2 is undoubtedly the best system I have ever owned.
