Can't help but think that the way it sounds with Ron's kit, that the PB-2 would be a good mate with the HE-4's also; taming that treble and giving that boosted bass some softening and texture.  Time to make a purchase.

 Has anyone tried the  PB-2 with the Beyer T1?



I haven't tried the T1, but I have a set of DT-880 Dragon V1's (600 ohm) with  Black Dragon cables, balanced.  It sounds outstanding with the PB2/DB2 combo.  I can only imagine that the T1 would sound even better!

I am listening now with T1 and PB2-DB2 CLAS combo (single ended) and I don't feel the synergy is great compared to ther phones I have here. Modest they may be but I find the HD600's (balanced) sound absolutely fantastic with this combo. The HE-500's probably beat them slightly in terms of SQ but the SS on the HD600's is lovely. I suspect OpAmps will have a part to play in this so for information the DB-2 has stock LP Filters. The PB-2 has LT1678's L/R and HA5002 buffers.

Thanks for the info.  I find that single-ended is really missing the dynamics and sound-stage, plus it's definitely not enough juice for that 600ohm load.  Was considering T1 or LCD-3 to compliment my HE-6.  Turns out the HE-6 has a different sound on it's own with the PB2/DB2 (Ron's Kit ofcourse), different from the NFB-10SE that I also like.  May just keep the HE-6's or buy another pair.

Interesting.  Received a new PB-2 while the 1st is being sent out for repair.  This one is very quiet, and no hiss where-as the 1st had a lot of volume-knob noise and hiss around 2-3pm on the dial - high gain and low gain.  Better production than initial batch?

So what exactly is the difference between the 1612 and the 1642, and which one is preferred with the DB2?


I personally prefer the OPA1612 as it has lower THD, higher slew rate, lower noise and, IMO, is better balanced throughout the audio frequency band.

There are others who prefer the sound of the OPA1642, so YMMV!

Hiflight's topkit turned my DB2 into a mini-Beta22.  Highly recommended!

I received my DB2 today. Pairing it with PB2. I used to own the DB1 and I have omly used usb from my pc. Switching from DB1 to DB2 I thought I should also buy a MF V-link (usb>spdif) and try that as a small upgrade. How many of you guys use only usb and not spdif into DB2? Does anyone have experience with coax versus optical on the DB2? Which one should I go for?
Thanks.

I don't personally have experience comparing the two but from what I've read from many people's posts, it seems to be the general consensus that coax > optical. Make sure you have a good 75ohm cable for it though :)

Oh that is really nice. Where can one find short cables like that? I'd hate buying 1 meter coax when i only need 10 cm. Are all these short cables diy'd from knowledgeable users or are there online stores that sell these?
