One other note, even if you don 't use the optional class A buffer the output impedance at the balanced outputs is pretty low. Something like 150 Ohms. Many people will elect to go this route to drive power amplifiers as even a 10K load would work just fine, in fact the only effect of the load would be to very slightly attenuate the signal and of course change the corner of the high pass.

Russ, out of curiosity, what do you use for your 'reference' balanced power amp? A Sympatico or some other custom design?

That would be nice. Even with 20 watts it can drive many full range, high efficiency speakers.

Yes it absolutely could be scaled up. I am not sure what sort of THD I could achieve, but it is in the realm of possibility. I may try it.

Default Legato at twistedpearaudio.com

Russ or Brain,

please check the description of Legato at twistedpearaudio.com.

The text seems to be a copy of IVY.

Cheers

Hi Russ,

Which SE conversion option would you recommend, the onboard Ballsie or transformers?

How much improvement does the Legato+transformers combination offer over "pure transformers" (directly wired to DAC's outputs)?

Thank you in advance,
Alex

Nice to see legato listed on the site! Did I miss a first round of sales, or is it not in stock yet?

Cheers, James

I quite fancy a version with a FET/bipolar CFP - is this part of the kit, or specifiable?

This was a temporary error. I am using the IVY page as a template for the Legato page and was not done editing it.

For those who have ordered an IVY but are thinking they want a Legato instead, I will be adding an option to the Legato page for "Swap my IVY for a Legato". If you select this option, I will ship you a Legato instead of IVY and refund the price difference.

At this point, the only think holding up Legato sales is measuring the total kit weight for automated shipping cost calculations.

I hope to have it all ready to order tonight.

Default Transformer coupling

If one were to transformer couple the output of the Legato (balanced to balanced) one could likely omit the output caps, and maybe even the filter circuit caps (considering output transformer bandwidth ~150 kHz), is my thinking correct here?
Looking forward to using the Legato, thanks!
