Or take a big step up to the Lyr 2, and then some the excellent tube alternatives for squeezing excellence out of your 560's. Then there is the grill mod, Jerg Pads, Thurston's Far Out Grill Replacement, too put the cherry on top
!
or maybe try project ember. I was torn deciding between those two. I think if you want to tube roll like crazy, project ember is actually a much better choice as you don't need to worry about a pair of matched tubes (which easily more than doubles your price). project ember is the more budget-friendly option with similar performance and wider range of tube rolling options.
so my quick impressions of lyr 2 after a few hours is that they are a noticeable upgrade over the sub-$100 bravo v3 (both compared in stock configurations rather than with the same tube though). will try with the bravo with the lyr tube later to see what is tube and what is amp. The lyr 2 does indeed sound really amazing. I do have a bit of mixed feelings about lyr's current sound signature (which I assume is dependent on the tubes), and can understand why there were two members here that felt negatively towards the lyr 2 with the he-560. it does take your brain a bit of time to adjust to a new sound signature & i've only had a few hours of listening, so hard to critique sound.
overall, a vast improvement over the bravo v3!
bass presence and impact has improved by miles. easily to tell apart from the bravo v3. that was the whole reason that I decided to upgrade my amp in order to increase the bass quantity, so in that aspect I am very happy!!! The bass is now pretty perfect for my preferences.
Stock lyr 2 really does make the he-560 sing, but for $450, I feel like we can be a bit more critical of its performance. a minor quibble was that I did heard a bit of sibilance on a track I never noticed sibilance with, so I was bit disappointed there. of course that is totally more source/track issue, but weird how I never noticed an issue with the Bravo V3, so I have to investigate farther. I was wondering if anyone else here experienced something similar as me with the sibilance. I feel like my ear is not as critical as others, so if I notice it, it's probably pretty obvious.
It seems to me that if you get the lyr 2, you will probably be investing in a new matched set of tubes as well. The stock configuration of lyr 2 exceeded my expectations & I was immediately happy with it for the obvious boost in bass, but upon more critical listening, my enthusiasm has been tempered a bit. I feel like the most enthusiastic supporters of the lyr here all do not use stock tubes, so their comments can be quite misleading. So, I think you may need to be prepared to invest another $100+ on tubes if you get the lyr 2. I will probably not upgrade tubes as the pricing is too much for me to swallow right now after jumping up to the HE-560 & then the Lyr 2.
