Ultrasone HFI-780 Amp > Alo Rx

matrix m stage is 250.   i also like burson and meijer

i like the size of the alo  but wonder how it compare to my predator

I'm using a Little Dot MK V with my pair of 780's although I must admit it wasn't a perfect match right away.

Due to my source and their low impedance I had to use an impedance adaptor of 120 Ohms, then I upgraded the OPAMPs to two pairs of OPA637BP.

The combination delivers a very powerful sound which still can be gentle and always remains very detailled.

I currently have an Alo Rx but that's more for my portable setup I'm looking for a nice desktop amp I listen only to trance music. I consider myself a bass head hence the HFI 780's.

 

This will be my first desktop amp and hopefully last. I don't know much about the specifications all I know is that my phones are low impedence and a SS amp would be best or a hybrid with transformers?

 

I'd like something less than $400

Forgot to mention my source is the musiland monitor 02

HFI-780s don't need much to bring out their best.  I drive them with a KICAS (non-caliente) SS, but my favorite is the LDI+ hybrid.  I have also driven them out of various amps (portable and desktop).  You don't have to go $400.00.  Get the I+ hybrid.  It shines with low impedance cans.

Disclaimer- I have two pairs of HFI-780s- Blue Dragon & Black Dragon re-cabled respectively.

I also own 2 LDI+- 1x- MC33078P (stock op-amp) (Mullard EF92)

                           1x- LT1364 (opamp)(Tung Sol 408A)
 

@yianni: Only the impedance adaptor may be necessary even though there were other users with low impedance phones that didn't need it. Maybe I was a little picky, who knows. The new OPAMPs were just the icing on the cake, not necessary but very nice to have ;)

Rudistors match Ultrasones very well. A used one could be an alternative.

Could not tell you, I have never listened to the rx, but the I+ is a solid choice with flexibility....Sorry about the late reply....did not catch it.

same situation here , i have an ignored thread sinking down the forum( lol , i never get replies) but the  ld1+hybrid  sounds ideal for me as well as i also have the hfi780s ,enjoying them very very much with a caffine ultra amp(lets face it,its the arrow without the bells and whistles) but i think i can squeeze a little more out of these wonderfull headphones

The 780s sound very good with my Dynalo. I'd assume the Sheer Audio HA-006 would sound good as its based off the same design. In comparison to my old RX, the sound is much more vivid with the Dyanlo and the bass is more authoritative.I found the RX to be smooth sounding, but maybe a bit too soft. The Dynalo adds greater imaging and detail without sounding harsh.
