Hi Andrew,

Thanks for the advice. It is both annoying and scary to hear such loud pop at loiud listening level. Hope to get rid of it soon.

Hi Salas,

It is quite amazing not to hear hissing at such volume setting. I had a Rubycon ZL across 33r resistor for the additional 5dB gain. With stock components (and a 4.7uF Elna Starget NP output cap), I am hearing excellent width and depth. Voice is clear and low on sibilance. Violin is natural sounding. Would have loved a more full bodied midrange that I think can be improved with proper RIAA caps, inter stage cap and output cap.

Compared with my Shigaclone/Monica 3 DAC powered by a v2, they are almost equal in terms of noise level with the vinyl set up generally sounding more organic (in voice, etc) with better bass extension and slam.

@Tham

Very nice so far. Even impressive. You did not tell me if you can modify the T amp's gain and what is the SPL sensitivity of your speakers. ...And any photo?

P.S. As you know from others in this thread, this is a very component quality responsive circuit, you will have lot of tuning fun when you will start playing with them.

Hi Salas,

Using a Charlize T amp. Not sure if I can increase the gain at all. Speaker is a Coral 8A40 fullranger in an angular spiral horn enclosure coupled to a pair of diy subwoofers and recently added vintage Coral supertweeter for a truely fullrange speaker system. Sensitivity shall be around 96dB.

Can take some photos later but will have to learn how to load it here.
