Can someone figure out the gain of this amp?

The new Mcintosh MA352 has a tube pre section and solid state section, by looking at the specs below, can someone figure out what the gain is? Most amp specs I see, if listed, are usually around 28db or so. Just curious for this new integrated amp. Thanks ahead of time

Ahhh. So since I have to use a passive pre ( between pre and amp) to lower the gain (super high tube hiss) with my system now( Zu Omen def speakers), I’m looking at super high hiss with the Mac but without a way to lower the gain. That changes things a lot since I love my Zus.

Abery, I am not sure why you do not just try a " better quality " passive pre ( my Luminous is totally invisible, and fabulous ). I am not stating additional gain ( preamp ) is bad, but speakers such as yours, and the high gain of the STA200 ( not to mention, 1 less pair of ic's ), would be killer....I use my Luminous with a dozen or so rotating amplifiers ( not just the Nuforce ) and I get plenty of gain on every one of them. You seem to be all over the map, looking into every new product coming out. Contact Tim Stinson at Luminous ( tell him I sent you to him, as I was a beta tester for him, and I get nothing from this ), and he will discuss with you, with complete straight forwardness and honesty, the truth...( my unit is single ended, has 3 pr. of inputs, 2 pr. of outputs, has remote, and is silent ). ( Maybe, he can give you a 30 - 60 day trial, IDK ). The Luminous requires, ime, a few hundred hours of break in, as I believe, ime, everything does ) It is " night and day " superior to your Schiit SYS. Stop the insanity. Enjoy ! MrD.

I was actually looking at the Hattors at one time

Over the last few months, I have moved my listening room to another area and have added room treatments, etc. My sitting position is a little further back than previous room (listening triangle). Anyway, today I decided to remove the SYS passive pre from between my tube preamp and high gain amp. To my surprise, the hiss is only noticeable when I am closer to speakers or if I am actually listening for it. I have always expected tube hiss of some sort. Removing the SYS has also seemed to "open" the system up a little. Thanks for all the info above

Glad to hear it. The SYS, along with the additional set of cables, would obviously be detrimental to the sound, other than for the purpose you initially intended. You should have, an almost new system, with it opening up. Enjoy ! MrD.
