Aussieamps Posted July 1, 2017 Author Share Posted July 1, 2017 (edited) OK so we have the following possible features for the Zero-Five-Zero SE. Might have to rethink the Model number to One-Zero Zero SE, open to suggestions? 100W 8 0hms - 200W 4 Ohms - ~400W 2 Ohms, The 2 Ohm Power rating might be quite an ask; to sustain 2 ohms both channels would require lots of output devices lots of filter caps and a very large power transformer. Around 1.5kva core would do it. 3 RCA inputs, 1 Line Out HQ volume control AL machined Front and back panels Initial case size 300mm x 200mm x 150mm With the possibility of making it deeper?

Administrator Marc Posted July 1, 2017 Administrator Share Posted July 1, 2017 HT Bypass seems a popular feature these day (I know it's a must have for me). Power is more than enough for most people. I only use XLR in my system, but appreciate I'm not the in the majority I suspect. Link to comment Share on other sites More sharing options...

Power is more than enough for most people. I only use XLR in my system, but appreciate I'm not the in the majority I suspect. HT Bypass can be added. One XLR input could be an option, the 050 amp has a balanced input by nature but adding a mixture of the two input types can be a bit messy. balanced volume controls adds a lot more complex wiring, so it would be simpler to have unbalanced volume control for the RCA inputs and have an active balanced input which is then converted to unbalanced internally to the volume control.

rantan Posted July 1, 2017 Share Posted July 1, 2017 I do understand this will be a special edition,but it may be worth considering that we shouldn't over egg the pudding . Case in point. Do we really need an amplifier that makes 400Winto 2 ohms? Seriously ? I think 100W into 8 and 180 into 4 is absolutely sufficient, with 2 ohm capability for short durations as is the case right now with the 050. We are not building another Krell here. I also think this should be as minimalist as possible while still being useful for most people and also for keeping the price affordable for most people( around $2K ) and I don't think we need a Swiss Army Knife amplifier. As Anthony has stated..............2 or 3 RCA inputs, HQ volume control,line out and remote would be ideal Just my 02 3 Link to comment Share on other sites More sharing options...

Not necessary to over complicate things. One balanced input and 2/3 RCA inputs just to keep both sides happy. Maybe Holton One Zero Zero SNE (Stereo Net Edition)? EDIT: Oooh, also maybe an orange LED on the volume knob to go with the SNA logo! Edited July 1, 2017 by Cardiiiii 1 Link to comment Share on other sites More sharing options...

Large power supplies are very expensive. So keeping the power output to around 200 watt per channel into 4 ohms with the ability of short sustained bursts into 2 ohms would be a better way of going. 2 Link to comment Share on other sites More sharing options...
twwen2 Posted July 1, 2017 Share Posted July 1, 2017 If it's going to be minimalist (and it should be), then ditch the XLRs and forget about a phono stage. 2 Link to comment Share on other sites More sharing options...

Phono stages and balanced topography add a lot more complexity,but I certainly don't claim technical expertise here merely a lot of experience with a wide variety of amplifiers over many years ( just like many other SNA people ) Link to comment Share on other sites More sharing options...

rantan Posted July 1, 2017 Share Posted July 1, 2017 One little ( but most important thing ) please don't make it with a blue LED for the power light indicator. Pale yellow, green or maybe red are fine Link to comment Share on other sites More sharing options...

Seriously, you want to fundamentally change the design now?Some of you guys need to take a breath and think a bit more rationally about this. We're talking about a special edition of an existing design, not "here's my shopping list for the perfect amplifier" that would require a ground-up redesign. 3 Link to comment Share on other sites More sharing options...
Administrator Marc Posted July 1, 2017 Administrator Share Posted July 1, 2017 I think that's a fair point. Let's leave this one with its feature-set as it is essentially. Perhaps we could work with Anthony on another thread for a "cost no object" or "amp of desire" for another build idea? 3 Link to comment Share on other sites More sharing options...

Agreed, I think we should take the basic 100W version of the ZFZ and turn that into the SNE. Not much fun if we add 'ideal' features, like Marc said, we can keep that for another thread. Besides, we need to keep the cost at around the $2k mark or we might be pricing most people out of this amp. 1 Link to comment Share on other sites More sharing options...
Upfront Posted July 1, 2017 Share Posted July 1, 2017 Ive been lucky enough to hear a few of Anthonys amps, including a few of these now and I'm not sure much needs to be changed. For a "basic" amp it puts others I've seen/heard in the same price range to shame. Link to comment Share on other sites More sharing options...

It it is important to remember that the existing 050 power amplifier is a very high performance amp at a budget price. most certainly you can always make improvements and make it drive 1 Ohm loads continuously if you really want to, but all of this comes at a price. The original brief for the SE is to take the original design and make it into an integrated amplifier and keep it minimalist in its approach; again to keep cost down. i am certainly open also to a "no cost object design" on another thread if others are interested 6 Link to comment Share on other sites More sharing options...
