If you are patient look for Audio Alchemy DPA-1 + PS 5 outboard power
supply (I have these). It is also has a very fine DAC and a headphone
jack, or, after this, Peter designed a dac pre streamer for Elac, but it doesn't have a outboard PS. Enjoy The
Music gave it very high marks
Preamp SS to match class D amp
I have been reading quite a lot and unfortunately I cannot find a post who can guide me into a match between SS pre amp and amp class D. Going through forums people ask advices only on tube pre amp to combine class D amp probably for the fact of the colorations of tube and some sterile class d amp they own. I recently bought some Belcanto ref600m as I got rid of my Mcintosh 8900 who sounded too 80s hifi and I wonder if someone can suggest a good pre amp to link. I would like to have something well build, dual mono if there are still, with balanced input and output. Considering that I listen mainly vinyl, analogic circuit I am thinking. Question as well, is there any preamp with streamer and Dac or these are only digital? As I would like to have a Dac as well to attach and I am wondering if make sense to have another extra gear
thanks
thanks

Thank you Atmasphere for the accurate explaination who add value to this post and as well to Mapman to report his experience with Belcanto. I tried Belcanto preamp with old version of chip that was Icepower and I didn’t like, sounds was compressed but changed with external preamp. For what I understood class d preamp (so I assume most of the one who have streamer functions or Dac) are not evolved as the latest class d amp so is better to look for a traditional SS. I guess that Nad pre amp are class d circuit base however is true that AVM are transistor based the latest ones. Here i know the national distributor and there is a lot of second hand available for good price, Germans usually go to bigger brand like Burmester if they pay cash and brand new. For AVM I know the previous serie and was ok nothing to make say is a miracle, however if a ss state preamp 10 years old had same technology I don’t go for a new product. SS preamp didn’t had significant jump in technologies in the past decades and no so many brands are still investing in these as people trend is class d or all in one system. So can you suggest me an old good as pre amp, if with phono even better, but a proper pre amp that I might find on second hand |
Bryston makes a nice SS Pre for consideration. https://www.stereophile.com/content/bryston-bp-173-line-preamplifier |
beppep OP We found your your Belcanto Ref 600M mono’s (that use Hypex NC500 modules and buffer) had a good sound "for Class-D" when they drove a two way speaker that had a Rahl ribbon with very benign 6ohm load and the mid/bass was also a benign load. Your lucky in that your Harbeth 40.1 are similar, in that they have an impedance load line nearly always above 6ohm, and a -phase angle that is very low, the only time -phase is high is at 55hz but then the impedance is nice and high at that frequency also, so it nulls it out. These speakers are kind to Class-D, if you change speakers look for similar loading. https://www.stereophile.com/images/archivesart/1008harH40fig1.jpg As to your preamp question I don't use one, I have a pair of the Hypex NC500's here also but driven direct from the dac to their balanced input stages with no buffer before it, and they also have a huge Linear power supply instead of SMP like the 600m have, they do sound good in my second system that uses speakers again with very benign loading.
