Re: Lejonklou Gaio
Hi all, just curious as i learn more about audio hardware - is the Gaio a high negative feedback design? low? none? Hi FalseMetal666! All my designs use a lot of negative feedback. The best way to make a great sounding circuit is to design one that is as linear and well behaved as possible and with...

Woofer Pumping
I run a Denon DL-103 on a Technics arm and have been observing some woofer pumping in quiet passages. Leads me to believe the compliance mismatch between the cartridge and arm are a bit more serious than I’d thought. Leads me to my question: does the Lejonklou Gaio have a rumble filter and if not, c...
Re: Gaio 2
I don't suppose it would be possible to upgrade a Gaio 1 to 2.4 spec? Apologies for my late reply, Falsemetal! In theory, it's possible. In practice, it's complicated and time consuming. Therefore I decided when Gaio 2 was released that an upgrade from Gaio 1 wouldn't be offered. It would be too ex...

Re: Lejonklou Gaio
Thanks for the warning. The turntable is currently grounded to the transformer which, in turn, is grounded to the Gaio.

Re: Lejonklou Gaio
Makes sense to me. Mostly just curious because I have a new step-up transformer coming in from Auditorium 23 and they don't publish their step-up ratio. I've seen numbers that suggest it may be as low as 1:8, so the Gaio could see as little as ~3.5mV. But it seems that is more than enough to be comp...

Re: Lejonklou Gaio
That does make sense. I guess, then, the better question is: would an input voltage of ~3mV be enough to properly drive the Gaio?
The input sensitivity of my amplifier is 200mV, so if I'm doing the math right, the Gaio would only need to see an input voltage above 1.96mV?

Re: Lejonklou Gaio
Just out of curiosity, what is the Gaio v1 input sensitivity?

Re: Testing MC step up transformers
Fascinating. Looking like I'll be placing a parts order momentarily.
Planning on getting matched pairs of tantalum resistors...any suggestions to the contrary?

Re: Testing MC step up transformers
Yep, I'm running a Denon AU-103 transformer with 1:10 windings, so I believe the Gaio is seeing a 470 Ohm load. I recently replaced the Bellari transformer I was running, which was wound at 1:12. I've been considering messing around with some parallel resistance jacks in the transformer outputs, lik...

Re: Testing MC step up transformers
Since I own a Gaio, and cannot imagine modifying the 47K input stage, would building some resistive loading jacks for the step-up input work? See pic below. http://daveyw.edsstuff.org/vinyl/loading/Files/b.JPG I am a bit unclear if a single resistor in such a jack would be in series or parallel with...

Re: Testing MC step up transformers
My set up is modest, and I've only ever had budget equipment until now, but I am surely very happy with my Gaio v1, fed by a humble Bellari STU and Denon DL103.
Beats the pants off of my previous Clearaudio Nano v2 (as it should).

Re: Lejonklou Gaio
The turntable is indeed grounded to the Gaio, but I'll have to make a custom ground lead to connect to the transformer as well. As far as the sound: it's lovely. The Gaio/MT502 is a replacement for a Clearaudio Nano v2. Though very nice, the Nano was a bit noisy in high-gain mode. The passive gain s...

Re: Lejonklou Gaio
Hello all, First time poster here. I recently bought a very clean Gaio v1 on the second hand market. I am running a Denon DL-103 cartridge that has fairly high gain - it tested at 0.41mv. The Denon feeds a Bellari MT502 step-up transformer which in turn feeds the Gaio. The MT502 is set to 20db of ga...
