Amp & Pre or Integrated for Dynaudio Heritage Special

One of the big Musical Fidelity integrated amps will do the trick. Maybe a M6si. But I have to say that would not be the way I would go. You can only get so much out of a little bookshelf loudspeaker. You really want the power and weight of a good floor stander as your next upgrade. Maybe a loudspeaker that matches your PrimaLuna a little better.

I’ve had giant floor standers in my room before and love the scale but they couldn’t properly disappear. Probably has a lot to do with room size, etc. The HS really give me more sound than I need and the soundstage is incredible. Haven’t heard the MF gear, but have been tempted to try one of the Nuvista amps.

How close do you think you are with your current setup? The tube front end like your hybrid has is a good idea. Have you tried rolling the tubes at all? It should have enough power unless you’re going for broadcast levels or have a dead room.

With separates you might be able to get closer to the proverbial iron fist in a velvet glove. It just depends on where you think you are and where you want to go. Do you need more iron or more velvet? A different tube type in a separate pre might give you more options. Maybe PrimaLuna isn’t as good with SS power as they are with tubes. Do you want to get a sub and run your speakers hi-passed? There are options. When you listen try to narrow down what exactly you are missing.

I listened to both the AR I/50 and the Luxman Discontinued Class A (forgot the model) both sounded great with the Hertiage Specials   Very nice speaker

The EVO 300 I have is a full tube integrated.  Definitely could you more power but it's close with the right power tubes.  Maybe an interconnect can give the sound a little more meat on the bones, which is something lacking.  Also, I'm currently streaming and although it's a good setup, not sure it does the speakers justice.  Would physical media like CD sound better than a good quality streamer?  Not sure I want to venture into analog, but would be ok with trying a cd transport.  

Streaming or CD would probably come down to the DAC implementation. There are a lot of choices that cover the gamut. Maybe something R2R would give you the extra heft you’re missing with your current DAC.

Not sure why I assumed you had the hybrid. As inefficient as the Dynaudios are I can see the fully tubed 300 falling just that last little bit short. The more powerful tube types don’t seem to have the same sweet midrange magic as the EL34 though. Maybe the 400 would be just enough power, but doubling the watts only gets you 3dB more headroom. I still think a tubed pre with SS power might do the trick. Know anyone with an extra 100W+ amp of suitable quality that you can borrow to try it out? Maybe a Modwright or a Pass?
