I last week I took delivery on a used 300DR built in 2017, in great shape. I’ve been looking for over a year for this amp @ the right price and condition and finally it showed up last month. Currently I have a 250DR, circa 2016. I love the 250DR and but always wondered what “more” can a 300DR offer? Now I know. Although I was told I should be fine with a 250DR, I wasn’t convinced I was taking full advantage of my Wilson’s. The 250DR is a great amp, I’ve had no issues with the performance other than at higher volumes it can run out of steam a little bit with my Wilsons (both Sabrina and SabrinaX). My SabrinaX’s are rated with a 87db sensitivity with a power recommendation of 50-200 amps.
I have medium sized room.

I listened to some of my usual favorites with my new 300DR and was very impressed. Then I switched back to the 250DR so I could listen to the differences more closely. Tunes included…
Daf Punk Random Access Memories Give Life Back to Music, Lose Yourself to Dance, Get Lucky
Aphex Twins Cheetaht2 (Lt Spectrum)
Ulrich Schnauss A Long Way to Fall A Forgotten Birthday
David Bowie The Man Who Sold The World The Width of a Circle
Elton John Tumbleweed Connection Ballad of a Well-Known Gun
REM Document Oddfellows Local 151
Dire Straits On Every Street Heavy Fuel
KebMo’ Blues America The Worse is Yet to Come
KebMo’ Just Like You That’s Not Love
What I noticed with the 300DR compared to the 250DR (no surprise really)…
Slightly more detail at lower volume @30. For example, I could hear the handclapping on Lose yourself to dance more clearly. The difference wasn’t huge w/my system, room & ears.
Once I got up to a medium/high volume @40 I noticed an overall smother, cleaner, there was no feeling of taxing my Sabrina. @45 it was still quite enjoyable to listen to. Fatigue free listening @45. On the other hand, with the 250DR it sounds strained @45.
I feel the 300DR has a smoother upper midrange overall compared to the 250DR, this is especially noticeable a higher volumes.
The 3000DR bass was tighter with greater extension and less distortion compared to the 250DR. Both were tight, but the 300DR was lock tight. With the 300DR at 40 or 45 I could physical feel the bass waves from my SabrinaX. Thrilling!
Overall the 300DR is a much better companion with my Wilsons. I don’t feel it twice as good as the 250DR, but with my speakers the 300DR a substantial improvement in sound quality. Most notably at mid-high volumes.
