Good, with my Lyras i get a very balanced sound with a forceful and dynamic bass.
Treble is not lacking in any way in my setup.
I am using the MiiB tuning though.
This week i will build another one.
Salas, what are your RIAA values, i would like to copy that ?
I have asked before but it is easy here to loose the overview.

Miib tuning has a bit more treble and bass. +0.4db HF +0.2dB LF in my build by measurement. Add 1nF to the treble caps C2a, C2b and parallel 820k-1Meg to R9a R9b. Matter of tolerances. You are looking for 67.8k net. That way it goes near neutral so you can have an alternative listening session. Its a matter of taste and system integration mainly.
Could you please explain? Sound-wise or just hum-wise?
Ha, ha. Very close to my impression too. But there is no denial the red boards with green leds are becoming iconic
Any ideas how to get a bit more resolution out of it?
You can try a Z-Foil resistor as cartridge loading. It has a somewhat brighter sound then the Dales but not sharp. You can of cause tune the RIAA for more linear.
I think Ricardo has another option then Salas. I think he arrived at his values mathematically.
It also depends on the cartridge. Which one do you have ?

Proper system grounding mainly. They tend to rise in noises when referring both regs to a common power ground. At least in my hook up. They were conceived and tested as double mono from the start I think.
Lower the servo impact resistors to around 8K, using a cheap resistor from the noname drawer. Seems to have done the trick, although I still can't afford to leave the paradise in the open. It needs a housing to prevent excessive output drift due to the airflow around it.
At some stage I will need to change the servo impact resistor to something better though.
- does this resistor have a significant impact on sound? It's sort of parallel to the signal path, isn't it.
- is there a particular reason why the designers have opted to parallel 2 150K? Instead of 1 75K?

Listening the first time... far too early for a verdict but so far very nice. Detailed and exact but not at all overly analytic or harsh. I have to resist the temptation to make it louder. And then louder.
Servo voltage came down to 4/6 Volts after implementing the "real" RIAA network. Output offset still wanders a bit within 100mV but I decided to not worry about it (and switch on the power amps last).
I had to move the PS aways from the ampifier and now its surprisingly quiet even with no ground from the TT connected.
There could be a bit more gain - right now I'm using the nCores but I suspect when I use my belowed F4s I will not have enough gain. I'll worry about that later...
beautiful! Let us know how the sound changes with more hours of playtime....
Ricardos and MiiBs values are both given in the assembly guide. I would like to start a collection of RIAA values and the associated listening impressions
Fat Bob meets Helmut Brinkmann ?
(Auwaja, die gelber 443 sehen geil aus, sehr sehr niedlich, die Platinen mit Dr Phili)

Could justify another thread on paradise riaa only
Jacco - yes, Fat Bob. Kind of a long story that includes the necessity for returning the "first choice" TT and limited alternatives with this particular vendor. I was very unhappy with the stability of the drive so I built a motor controller (the shiny thingy). With a controller and two belts under some tension the drive became acceptable. The black box is the DAC, no Brinkman for me, at least as long as I pay off the mortgage.
Yellow Philis are a tip of Chris who posted his built earlier in this thread.
Joachim - apologies, I just realized I called you Gerhard earlier in this thread. Not sure why, I wasn't even drunk?

Like the idea of a Nak on C.... Did not think of it initially, but the low noise comes to that indeed.
Anyway it sounds cleaner than anything on Dolby C IMO.
The Z-foil for careet loading is a very good option... that is waht I have now and really is even better than the rgular shinkohs.
Hi Salas... Would you post all the riaa values you decided in the end... both caps and resistors please
H berndt cool idea
Brinkmann likes to put a stone under all of his products.
With the slate plate, and the LP clamp where it is on the picture, looks a bit like Helmut's top turner.
Only lacks a small pipe between motor and clamp, and a few buttons.
(prettiest HB design for me still is the Audiolabor Konstant)
Pound for Pound (£/lb, or in this case DM pro kg), the FB is Jochen's best product, imo.
Requires a solid stone platform and an RPM controller, but plenty to save there for a diy. Konstant Ref M1 isn't that impressive inside.
Each of your projects is pretty, Gelbschnabel.
(jr has a couple of personal friends in low places, 1 is from my home town)
