Digital Amp?


Maximus89

Recommended Posts

I'm considering moving from tube amps and external tube dac for a more simple solution such as a Digital AMP that takes only digital spif input(no analog inputs). Peachtree Gan1 for example. In order to double as hifi/home theater, i would need a streamer with HDMI video connection to use my tv streaming. There are plenty of options including HiFi Rose.  Streamers have analog inputs as well as outputs.  I was curious if i wanted to keep some tube sound, would my transformer coupled tube preamp w/ tvc work outputting into one of the Streamers analog inputs while digitally outputting spdif out to the digital power amp? Or i would only be able to set the streamer to digital out and not be able to simultaneously use the input to get tube benefits?

I have no answer to your question but I’m curious about this preamp of which you speak. The only one I’m familiar with like that was one produced by Antique Sound Labs. Is there another?

Audio Tekne TP-8201 from Japan, i have the fully transformer coupled matching power amp up on ebay and audiomart if only b/c it's just too damn hot in Tx and quad matched power tubes aren't cheap for how often i double my system for both hifi and regular tv/movie watching.

You may want to check this one out...you can also set to line out ahead of your tube preamp, in order to take advantage of the DAC and HDMI inputs while retaining your tube sound, if desired:

Thanks i didn't think of that.  I have had the cheaper model Evolve-II-4k for years, but that model only has multichannel analog outputs. 

The model you listed would work with a digital power amp, but how exactly would i get it to work with my Tube preamp if it has no inputs?  I would need to output from my Tube pre to an input, no? I've never thought about that. Will a preamp work with no outputs connected and only an input-digital power amp to that input device?

 

Either way, i believe i would run into the same issue that Hifi Rose tech support says. I can NOT both digital out and use analog input simultaneously. I'd have to switch input to one or the other.

You should double check with Bob at Essence, but, I believe you can select the stereo (analog) mini jack input (L/R rca to mini jack out of your tube preamp into the Essence unit) and it will output through coax, toslink/optical or HDMI digital for connection to your digital ready amp.

Yet gonna be unhappy if moving from Tubes to Chip Amps. 🙄🙄

 

BS. There are just as many, if not more crappy tube amps than "chip" amps. Execution and skill of the designer/engineer are far more important.

 

My most recent "chip" amp is a NAD M23 and it is absolutely killer. I haven't felt compelled to use any of my tube amps since installing it last April. And, just for the record, I have a LOT more tube amps than "chip"/solid state.
