The funny thing is... that code "July22" was only supposed to be for $20, but it took off 20%. I see that they've relisted the item after saying it was sold out. Mine has already been shipped, so I'm really happy with the deal.... looking forward to checking these out.

Incredible deal! I had to pay 399 for the Aeon Open with the 20 off. First ever order from Drop and first ever planars for me. I really dislike that they absolutely chose the slowest UPS shipping rather than let us choose the shipping for ourselves. 9 days and counting so far from NJ to CA and cross fingers they get delivered tomorrow
Looking for amp, had the jds labs atom amp. Even with gain, couldn't tell if there was any low end being produced unless knob turned up. I'm guessing it's a current issue ? Looking at the asgard 3 with DAC. One thing I don't like is having two separate amp/dac multiple plugs ect. Desktop and portable are being considered.
How do you define "low end"?
However you choose to put it, the JDS is a reference level amplifier and switching to another just won't make any big difference unless it's flat out broken.

I also endorse the Atom. I use it to drive very low impedance and low sensitivity DCA headphones (i.e. current-hungry headphones) and it has power to spare. The Atom is not your problem.
The Topping DX3 Pro is a popular and affordable desktop dac/amp with good power, good features and great specs, since you mentioned possibly switching to a single box vs. separates. A very nice Sabaj A20d was reviewed here on ASR recently and sounded very good as well but with more features at a higher cost.
For dongles to use mobile with a PC or cell, look at the Hidizs S9 Pro or the E1DA 9038s G3, which both deliver good power from a USB source including current for low impedance headphones, especially if you use 2.5 mm balanced cables which will then provide more power than SE cables. (The Hidisz has both 2.5mm balanced and 3.5mm SE; the E!DA 9038s is balanced only.) If you're using a cell as a source and want to be able to EQ it from the cell, look at the Qudelix 5k, which also can be used with balanced cables. If you need portable battery power in a dac/amp (rather than using a PC USB connection or the cell phone's power), check out the ASR reviews section. Most of this is reviewed on ASR except the Hidizs S9 Pro that I use all the time, for which the current model has more power than the S9 version reviewed on ASR.

This is a review, detailed measurements and comparison of Schiit Magni 3+ and Heresy Headphone Amplifiers. It was kindly sent to me by the company. They both cost US $99 plus shipping from Schiit. The Magni 3+ is a discrete amplifier implementation whereas the Heresy uses integrated circuits...

When one (momentarily) wants to reach impressive levels (cranking it up very loud) and never want to run into limits one needs 14V (120dB SPL)
This is 15W peaks (so about 2W average) at those moments.
An amplifier that is rated into 8ohm would have to be 25W and a 4ohm rated amp would have to be 50W.
Those that like to always do the sensible thing can certainly get by with a 2W (13 ohm) rated amp.
Those that never go beyond any sensible levels can get by with a 0.2W/16ohm rated amp.
Of course when listening levels do not exceed this 0.2W there is absolutely no difference in sound then when connected to say a 200W/4ohm amp.

This is 15W peaks (so about 2W average) at those moments.
Below 100Hz where music is usually loudest, only 6.2W would be required to hit 120dB SPL Peak on the RT Closed.
At 425Hz where Amir calibrates his headphones and IEMs, the Amp would have to output 13.8W for 120dB.
