Sennheiser 590, HD-25 II, PC-100 and some ancient Koss (can't remember the model). Sennheiser 600's will be ordered for this and my 590's and Szekeres will be retired.

Can do all those cans no problemo. The one that uses it in line preamp duty only (at 4xGain driving the power amp for his Eminent Technology inefficient large magnetostatic panel speakers) listened to it first time over headphones (HD-600s) yesterday and he commented very positively, will also add a phones socket to his build he says. He had built a boatload of different DIY preamps both SS & tube in his hobbyist career, so keeping it for so long in his rack is a good sign. Few days ago a former neighbor came around visiting and saw it so he came back the next day with his AKG K701s saying he wanted to know if he will ever manage to really like them. He has a Benchmark DAC1 as headphones amp. He had left liking them LOL :D

Count me in if a GB goes ahead.

I will be starting a GB thread shortly for it and the DCSTB board.

I will add a link to my signature and add these into another GB since I am mostly out of the other boards as well. Some people may want to try this with a BIB board. I on the other hand want to try a DCB1 with a the DCSTB to see how it sounds :) Keep on exploring.

We have an unorthodox guy here. :D

You would need to jumper four out of ten DCSTB Leds bringing it down near the +/-10V DCB1 spec by the way. Maybe in-between ones to look nice. :)

Can't wait for the GB.
Hope that there is kits available as well.

DCG3 Latest Built

My DCG3 built now with 2 nos +/-17.6V BIBs for true double mono. More refine, smoother, better separation and a wider/deeper soundstage is the initial impression.

What was the original regulator type you tried

Tham 26th September 2016 09:28 AM

It was a single +/-17.6V V1.2R reg configured in 2 wire mode.

It will be a transistor kit option (with appropriate matching) and a full kit option.
