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.

I purchased the Synthesis A40 to power my Dali Epicon 2 monitors. When I got home I connected the A40 to my primary system consisting of Franco Serblin Ktemas. Needless to say, the amp never left the primary system and now powers my Ktemas. Plenty of power.

I mainly listen to vinyl through it, but when I compared the internal DAC to the Accuphase DC-37, well I prefer the Accuphase. With this said, if needed, I would be happy with the A40 DAC. I also purchased Audio Note speaker cables to go with it. Good combo. 

I listen to my Accuphase setup mostly, but for listening sessions with the right music I switch on the Synthesis. I am happy with the purchase. Glad to hear others are well. Sounds like we purchased from same dealer in NOVA

As stated above, I am now an owner of the A40 for about week or so. I am currently listening to the onboard DAC via USB cable from my streamer. Yes, it sounds great with a warm sound signature. In contrast, when I listen to the A40 with my Accuphase D-37 DAC the sound is great as well, but slightly more analytical. 

On another note, Vu stated they are having problems with the new remotes. I have yet to use mine. He states they may be recalled. Have you heard this as well?

To be honest, I do not know. I have yet to use the remote. He just mentioned it. 

I just cannot seem to go back to my Accuphase A-70 after the purchase of the A40. I just enjoy listening to it. Is it because it is the new toy, perhaps. It is just more listenable than the solid state amp. 

Well, before I jump off the A-70 bandwagon, I just upgraded to the Audio Note Lexus cable and it made a huge difference in the solid state amp from the previous AN cable. The AN-LA cable sounded fine with the synthesis, but did not sound good with the Accuphase. Now, I can say both amps are equal in its value to the overall system. 

 

My Synthesis A40 still is running without issue except for a humming upon warm up. Also, I can get some audible noise when changing volumes. Is this normal? Deja VU did not seem concerned with it.

Side note, purchased a Chord Mscaler. Really adds a benefit to the A40 when using its internal DAC.

Glad to know the warm up hum is normal. I’m still enjoying the amp everyday. In my next residence I’m going to add the amp to drive my Franco Serblins. I’m excited for this. I have no doubt the A40 can handle the task. Currently, I’ve been listening to my Dali Epicon 2 monitors, which sound great. With the FS it will be Italian driving Italian. Match in heaven.

Just swapped the A40 for the A100. Big difference with my Ktemas. Game changer and worth the extra $$$$

I honestly do not know which KT66 tubes they are. It’s the tubes that came with the amp. Vu stated only a handful has upgraded from the 40 to the 100, but I chose to since I’m driving the Ktemas. I hardly ever use the internal.DAC, but rather use the MDave. I really want to hear the new FCO300B. I wonder if the single ended low power would be enough to drive the power hungry Ktemas. It’s the low end that often is neglected with other amps.

Yes, this makes sense. The high efficient horns seem to match well with the clones. Or, people seem to think they need to go with the nostalgia W.E. with the horns. I know VU, dealer here in the Washington DC area promotes the combo. Although, I have no doubt the Titan will do just fine also with these type of speakers. I will say though, it’s worth the upgrade from the A40. I did not consider the A50 since many prefer the KT66s over the KT88s.

I can imagine. The times I’ve listened to vintage Western Electric with matching vintage horns the sound is truly impressive. It’s big and expansive with a wide soundstage all while emphasizing mid range. It’s truly a visceral experience. With this said, I’ve always asked myself if I would be happy with this as a daily. If I did, I would go all in and completely customize in a forever home. Maybe.

For now, I will stick with my systems. Each one caters to my likes. Synthesis for tube, Accuphase for Class A and my headphone system. This scratches all my itches.

I wanted to add for those headphone listeners, A100 with a Zynsonix box makes a great headphone amplifier. Love it with my ZMF Calderas. Another utility for this great amp
