Integrated Amps

@rauliruegas Yes, I have upgraded my entire rig except for the CD player, which I really don’t use anymore but keep it in the rack for nostalgia purposes.

The rest of my rig: NAT Audio Symmetrical Balanced Line Stage, NAT Audio Magma M mono blocks, Herron VTPH-2A phono stage, Verastarr power cords on the mono blocks, Triangle Art Maestro TT with Horus 12" tonearm, Verastarr speaker cables, Cardas Clear cable from the phono pre to preamp. Audioquest Cobalt Dragonfly DAC and cable, Audioquest Dragon power cord from preamp to Transparent Powerbank 6 power conditioner.

My buddy has a 6k SS phono stage that he wants me to try. I love my Herron but now I’m open to trying it just to see how it sounds.

Look for an Ayre 

I took a demo Billie MK II home from my local dealer to try with some Harbeth P3ESR after reading some fantastic reviews. After 2hrs of listening at home I called them and ordered a new one in gold finish no less, lol. I swapped out the JJ ECC99s for some NOS Sylvania 12BH7s and the amp is now as great as anything I've owned at 2x the price. Interesting side note, the guys I got it from are the US distributor for Heaven11 and have #3 in their loft showroom. They are maybe a tad overly enthusiastic about the amp but I gotta say, the proof was in the demo with a set of LS50s. It was amazing in their showroom and even better at home with better speakers. The Billie could be $2500 and still be a great value. Just my experience

I owned the latest Heaven 11 Billie MK2, just sent it off to TMR for consignment. Lots of reviews online, but some important points.

a) It’s buried on their website, but Heaven 11 says DON’T use the amp with high-sensitivity speakers (10+ ohms). I tried the amp with some Zu Audio speakers and found it fatiguing and not a good match. This was before the warning was added. A tube integrated was a much better match for those speakers

b) Volume control bug. This KILLS me. Even with the latest firmware, if you lower the volume, it momentarily gets louder before the volume decreases. With the older firmware and the latest, I would occasionally flinch when lowering the volume because it gets louder and it’s not what you’re expecting. This "little" issue alone kinda killed the amp and as a standalone preamp.

Lots of features, it’s beautiful. The owner (Itai) is very nice in emails. I had some issues with the headphone, so I don’t recommend it if you plan to use headphones. You can change the sound a bit with different tubes, but their Gold Tubes are quite good. It wasn’t bad with Buchardt S400, but it wasn’t my favorite amp/speaker combo I auditioned.
