Hello,
I do own a Bryston 1.5 phono. I have owned (recently) Audio Research Ph-1 (average, sold) Audio Research PH-2 (nice, balanced in out, sitting here) Audio Research Sp-10 (over hyped, tube dependent, sold) Audio Research Sp-15 (pretty good tubed phon section, currently temporarily my second phono stage)
The Bryston 1.5 is exceptionally clear, warm sound with my Benz Glider on a Rega P5. Would I buy it again? yes. If you have the power supply already, it is a decent value. If you have to buy the supply too... go for some others..
I DO have to say I bought one 1.5, then ordered a second. The second one's serial number was consecutive after the first one. BUT the second one had a better sound. I do not know why. I actually decided I would be constantly disappointed listening to the first one, and so I returned it and kept just one, when I WAS going to keep two. I am now using the AR SP-15 temporarily for a second phono stage.
Also, the first 1.5 had a front face with squared off ends, and the second had the bevelled ends like later stuff. I have no idea why the two 1.5's were different.
More of the story. I bought the first one, Then when I returned another item I did not like, I used the money to order a second Bryston 1.5 I asked the dealer to tell the factory I wanted the MC input to be 100 ohms. Anyway, I get the second 1.5 and after using them a bit, realize the second one just sounds 'better'. If I did not have BOTH, I could never have said anything was not great about the first one. Just the second one had a warmer, nicer sound. I had the dealer send back the first one to ask to adjust the Mc impedance. Bryston's US service center sent it BACK saying it is not changable. I decided, as I could hear the difference in the two phono stages, to return the first one. I just knew I would always be unhappy that one was better sounding to me! I actually had it for awhile, so I offered the dealer a 'restocking fee' to take it back. He did. I was happy, he was happy.
I tell the whole story to note that the same chunk of parts can be different. They should have sounded exactly the same. I tried every different combo, swapping cables, cords, carts..(also checking the internal jumpers) the second one just had an edge over the first in a way I cannot explain. I was just better sounding TO ME.
The Bryston Phono is worth the money if you have the power supply already. It has little adjustability, and only one set of inputs, with a MC MM switch. (I use it in MC mode) but does have capacitance switches on back, and is always in standby if not on. I like it.
I am a clarity, and good high frequency freak, With PRAT. So if you want these things, the Bryston is great.
Sorry I am NOT so good at doing a review.
