Harbeth M30.1+Luxman LX-380 & Audio Note AN-E/SPe Oto SE Sig

The M30.1 probably sounds heavenly because it is driven by a tube amp (Luxman LX-380). I have only listened to the M30.1 at the end of a solid-state amp and although the speakers still sound great, it appears to me that they only sound good with specific music genres. In my mind the M30.1 is not as versatile as the Super HL5 Plus which is more of a balanced all-rounder to me. The M30.1 is particularly great for vocals, acoustic music and small ensemble jazz but falls short with larger ensemble music and pop/rock.

If the M30.1 sounds great with the Luxman, do stick with that combination. Tubes can sometimes give a little glow and illumination to the sound. The setup that I listened to sounded a little dull, though the same cannot be said with the Super HL5 Plus which sounded more open and vibrant than the M30.1 with the same (solid-state) amp.

The SHL5+ is a bigger speaker with more output at lower frequencies and greater dynamic headroom. Therefore it is the better of the two for symphonic repertoire etc. However, a very similar effect can be achieved by adding subwoofers to the M30.1

" Irish,
Nice system! I have the DAC-3 Signature which came before the 3.1x so I know your digital sounds great, and I use Lexus speaker cables too! The Oto is supposed to be a sweet little amp and AN TT's are very musical looks like a well thought out well sorted system. May I ask what speakers the J's are replacing?
Cheers,
Jon "

Jon,

They are replacing JM Reynaud Bliss Silvers which I run with Quicksilver Mid Monos

irish cool I've heard great things about JM Reynaud but never heard a pair. Sounds like you're in for a nice upgrade both amp and speakerwise!
Cheers,
Jon

Irish,
You have IMO a very nice and well thought out audio system.  I suspect you trust your ears which is the best path to follow.  No doubt that your system reproduces music beautifully.
