I took the plunge and cut down the pre-amp PCB to remove all the input switching and Alps volume pot - it will be a single input build with a better quality volume control and no remote control. I'm leaning towards using my Slagle autoformer attenuator.

Re: Pass Sony VFET Project
I hollowed out the back side of the panel to reduce the amount of material to be used in printing it, which reduces the cost.

Re: Pass Sony VFET Project
Just about finished the project today with the addition of a front panel (3D printed by JLC).

Borbely EB-1198/116 Preamp
I think I picked up the bargain of the year! I saw a pre-amp listed on DIY Audio - the guy said it was an Erno Borbely design but didn't know which one. I studied the photographs and had a hunch that it was the 1198/116 All-FET design so, as it was listed for a very good price, I took the plunge. It...

Re: OK…so I’m on wi’ summat
That's good then. Maybe just try the simplified filter board some time down the line...Cressy Snr wrote: ↑Sun Feb 18, 2024 10:04 am Now then! After squinting through the top plate mesh, with the use of a strong light and magnifying glass, I can confirm that the filter op-amps are indeed OPA1678s.

Re: OK…so I’m on wi’ summat
Good result Steve. I know I'm conflating two of your threads here but just to remind that, IIRC, the filter stage of your RTZ has NE5532 op-amps and it would be good to get you a listen to one equipped with the OPAs, which we've all found to be an improvement https://www.audio-talk.co.uk/phpBB3/view...

The 'trim' is a nice touch, Steve.

Re: RTZ SDM (DSD) DAC
I've removed the NE5532 and fitted the OPA1678's (Thanks Tony) Got to say guys just my opinion but I found the OPA's are noticeably better , its opened the sound up and sounds less compressed , better attack . Its obviously fiddly changing smd parts so caution if wanting to try it . Next thing to t...

I think that most evenings Ray Seems to be! 🙄 Love the look of that Beagelbone black , I need to look into that tbh I was expecting a huge PC was needed to run HQ player . You do need a powerful PC for HQ Player, mine is getting a bit old now but still benchmarks at something like 11000. The Beagle...
