Integrated Amps

Class D look for the gato dia 400s and a very good dac.

I went from Marantz to Musical Fidelity m6si and have been happy.   Gave me more power and a familiar but better sound.  I took my speakers to a few whops and listened to several to make sure they matched up.  If new speakers are on the horizon, agree with others to match them.  

Also, I use my old Marantz, repaired, to drive outdoor speakers.  Might work for headphones too depending on your situation. 

I resurrected my system five years ago by purchasing a Yamaha A-S3000 integrated amp. It was a huge sonic improvement over the Yamaha A-1000 integrated I bought in 1985. It was easy to discern because I had the same speakers, Infinity RS-4b’s.

The sonic improvement was the start of a very deep rabbit hole for me. I upgraded speakers next with Magico A3’s. Then I listened to a Prima Luna integrated amp a buddy let me use. That led to buying a Dynaco PAS-3X tube preamplifier. I paired that with the A-S3000. The sonics were an improvement over the A-S3000 alone!

I’ve since upgraded the preamplifier, the power amplifiers twice with two pairs of mono blocks, added a separate phono preamplifier, upgraded the turntable, cartridge, cables, power cords and added room treatments, Soon the power conditioner will be next.

I’ve enjoyed the journey but I was naive as to what I was getting into when I upgraded to the A3’s in regards to what it would take to bring the sonic level of my rig up to what I heard in the demo. My advice is to proceed cautiously.

Obtaining synergy between components most likely will become very expensive. I also have another rig which uses the old RS-4b’s with a Scott A 436 integrated amp and McIntosh MR-55A tuner. I enjoy that system almost as much as the main rig when I listen to it!

I would be wary of purchasing any integrated amplifier with a built in DAC. As enticing as that may sound, in most cases the built in DAC is inferior to even an inexpensive stand alone one.  More importantly, the resale value of the amp will plummet as soon as the manufacturer introduces a similar model with a new and improved digital section.  And we know how much that hurts when you inevitably decide to upgrade again.  We’re audiophiles!  I think the next big thing in DACs will be a near universal adoption of USB C inputs.  A couple manufacturers offer an internal DAC as an option on a plugin circuit board that, in theory, can be replaced with a more up to date board, which seems like an excellent way to stave off obsolescence in the fast moving world of digital.  I know that NAD, McIntosh and Accuphase do this, and hopefully other manufacturers do, too. Best wishes!

I just want to say the new NAD class d amps are very clean but there is no warmth at all. A friend just tried out the preamp / amp stack of the master’s series. Very clean but NO WARMTH. I liked it on Maggies, my friend did not. For what it’s worth.
