Never heard the metal base, but Lukasz says its much better than the ceramic. At 3x the price, it should be!

Yup, 100wpc and he is verrry proud of it, as can be seen by his quote...over the moon, actually!

It seems like the return of the differential summator circuit, for those Lampi Dac veterans from circa 2010.

Jazzhead, where are you located, if you dont mind me asking? If you dont want to answer publicly, PM me the response.

Wisnon ... Mumbai , India . Someways away from you . If ever thru these parts look me up . Cheers

Namaste bhai ! Look Forward !!! Do get in touch , will be great to catch up on all things audio and other Garam Masala

A good solution is to start SE, get the tube rolling fun out of your system, and if you decide you prefer the 101ds and have the amps, Lampi or whichever, that need a balanced dac, check with Lukasz if you can do a swap for some cost.

What's his system?

Cant recall, but he is also hunting speakers. He is a pal of Adam too. I can give him your contact details...or better yet have him register here and contact you guys directly.

Yes, give him my email as well

Will do.

Based on this review, it sounds like the Big 7 without pcm dac would be most cost effective and instead using computer to up sample everything to dsd.

That's what Elberoth and Audiocrack are doing. However I wouldn't go with the review based on the fact that his PCM wasn't burned in, and he did not use 101Ds.

Yes, DSD sounds better, and upsampling works as well, but all you will save (not sure but from memory it's 750 quid?) By adding PCM you retain the flexibility of playing native PCM, and doing some streaming when you are not doing serious listening. If you are not doing serious listening you might as well stream of Tidal, or use native from JPlayer (better user interface) for PCM

Yes, there is a significant cost savings (save 750 Euros) to buy the Big 7 without the PCM circuitry according to the Big 7 Price List.

So I stand corrected. 750 Eur, not GBP. I wouldn't give up PCM for that, for anyone buying a Big 7 and a quality transport, that is not much as a percentage

I'd agree. The PCM circuitry on the Big 7 is certainly worth having.

Audiophile Bill · Apr 23, 2015

Are there any performance advantages of just having the one engine? I.e. No switch, shared power supply, noise etc?

wisnon · Apr 23, 2015

The 2 modules are relatively independent and the PSU is way over specified. To my ears B7 PCM is outstanding.

Not sure how much improvement such a minimalist setup will bring, but I would not give up the PCM engine for that.

BTW, Audiocrack's GG has both DSD and PCM.

Yes , having both PCM and DSD boards nesscitates having an extra cap in the signal path , which seamlessly allows switching between PCM and DSD . This cap can be done away with for that touch of added purity , if you are willing to turn down the gain / mute the signal while switching between formats . Or else there emanates a boom , the technical reason of which escapes me .

Hey Jazzhead,

Did you get my PM?

Audiophile Bill · Apr 25, 2015

Sorry for basic question. I wondered whether there is software that enables one to convert PCM to dsd not on the fly as jriver/hqplayer but permanently as a new file with the dsd sample rate you specify. Why? Well would thus take the pressure of my pic from doing this on the fly? Also, I could play off USB stick or USB drive to my oppo.

Thanks
