Synthesis Amplifiers: One of High End's Best Kept Secrets?


Just stopping by to share my enthusiasm for my new Synthesis A100 Titan integrated amplifier. For the past few years, I have been on the hunt for the best integrated amp I could find in my price range. I've had a Line Magnetic 508ia, a Devialet, a Lyngdorf TDAI-3400, a Boulder 866, a Vitus RI-101 mk2, and a Vitus SIA-025 mk2 in the past four or five years. I enjoyed aspects of each of these amps, some related to sonics, some to functionality, and some to build quality. 

And yet, in each case, after several months, I found that I wasn't quite getting the sound I wanted--rich, three-dimensional. engaging, and dynamic without being fatiguing. Too often, I found myself picking the sonic picture apart, assessing this or that at the expense of pure musical enjoyment.

I finally decided to give up on my hunt for the "perfect" solid state solution and go back to tubes, which led me to audition the Synthesis A100 Titan, an amp that features an octet of KT66 tubes, a pair of 12AX7, a pair of 12BH7, and even an onboard DAC. I was intrigued by this amp, but found very, very little written about it in the audio forums (here and elsewhere), except the praise of a couple of folks.

I've had it about a month now, so while I cannot give a guarantee that it is my "lifetime amp" in light of my history of amp promiscuity, I can say with absolute assurance that I find this amp far more satisfying and exciting than any of the amps I've had through here over the past few years.

In short, I am just astonished by it. I had assumed that at the very least, the onboard DAC would be inferior to my Lampizator Baltic 3, which is just wonderful in every respect, but as I spend more time comparing, I am not even sure of that anymore. The onboard DAC is so good that I am now planning to try some different USB cables to see how much performance can be squeezed out of it. Very possibly, my excellent Lampi may soon be up for sale.

Just to be clear, this is no ad, and I have no affiliation whatsoever with any dealer or distributor. I just can't believe how good this amp is, and how relatively unheralded it is. So I am heralding. The Titan is a pure pleasure to listen through every night, and a magical match with my Fyne speakers. The presentation is utterly immersive, and spellbinding. I am no longer picking the sound apart. There's no need.

If you are in the market, I highly recommend an audition.

It is highly unlikely I will do this myself. Then again, the tech for Deja Vu told me that the KT66 tubes in the Synthesis last an average of six years. I'm not exactly fretting over it. I have a tech twenty minutes up the road who could do it, or I might send it to Virginia to have them do it when the time comes for tube replacement.

For context, I just sold an amp that retails for more than twice as much as the A100. If I also end up selling the DAC, interconnects, and digital cable as seems very likely given the quality of the onboard DAC in the unit, I will be pulling about $10K out of the system and still have sound I much (much!) prefer. For me at least, that's worth the nuisance of having someone else setting the bias on the output tubes when the time comes for that. Your mileage, as they say, may vary.

 

Agreed.  I would also own the same amp. No issue for me. I am sharing something folks living around the fruited plan should think about.  Also hoping the company or dealers read this so future product has probe locations on top of the amp. 

I get it for sure, Bill. This "quirky" design flaw could well be a non-starter for many, and I certainly wish they'd make exactly the adjustment to their amps you have suggested.

I will send this advice along directly to Synthesis, for whatever good that might do. All I can say to anyone out there is don't audition it unless you're willing to live with it :)

 

 

Awesome looking tube Integrated amp and the changes grannyring mentioned would be a worthy upgrade. I have owned manually biased tube amps and they all drift after 30-45 days of use as the tube ages requiring regular biasing to maximize tube longevity.
