I have sent a few emails to Amptastic but no response from them to the above question
On the website it says the amp cannot be used as mono blocks but can be used in a Bi amp
I want one amp for the mids and one amp for the treble I have a separate amp for the bass already
I am thinking of either Mini DSP 4 x 10 HD or 2 x 4 but not sure which one to go Probably be the 2 x 4 as I imagine the dac Not as good as the Caiman on the 4 x 10 HD
The other option I am thinking off is the Hypex UcD180HG and build a amp Read good reviews on the forum but its a big punt in the darkI want to get as close to Tony's amp as I can

IIRC Tony (Weeteecee on AoS) is using his Mini Ones in just this way John, may be worth PM'ing him  |

What Amptastic are saying is its the chip that cannot be bridged so in this case sounds like it will work as both using the same chip

Oh okay, thought he had the 'Ones' Bri, silly me... |

Think so but over the years I learned not to rush

I am now narrowed down my thinking to two different ways to go active I am seriously considering this way www.hifizine.com/2011/09/digital-direct-minidsp-stack/ but will depend if I can configure my active bass system into it This is pretty drastic route to take. But has better potential The other would be the amptastic route using mini DSP which at least if it does not work would be easy to resolve |

The direct way looks interesting John, but it could be fiddly to implement. I hope you'll keep your current amps to use while you're messing with it!

Yes what I like about the direct digital way is that it keeps it all digital so less conversion resulting in less jitter and as we know jitter is a killer in the digital domain
If I use the ampastic it would mean if using a MINI dsp 2 x 4 This would give 3 separate conversions Using the Mini HD only one conversion. Using Direct digital means everything stays in the digital domain until the output cables from what i read so in theory the best results of course until you hear no way of knowing
Must admit I like the Mini HD with two Mini 1 It gives a few more options and maybe sometime in the future go fully digital

I use two original mini ts as mono blocks.I use gotham y splitters on the phonos and y configured speaker cable. Both battery powered-bit of cheating really but it sounds pretty good and manages to cope better driving difficult speakers.

What are you going to do with the Salivation (sic) if you take this route, John? Will you try an A:D converter?

Would need a separate amp if I chose to go down that route

If you are thinking 3/4 way DSP, consider Diyaudio WAF Najda. Excellent ADC / DACs etc and all the control you'll need. Very good sounding. I use 5 amps, like active bi-amping but with three more amps  |

Thanks Steve I have a look at the site
What amps are you using
Be hgood to be able to do both ADC/DAC

Haha - we are overlapping with the thread that Mikemusic started on my speakers:)
I use 3 Icon Audio 5W SET amps for the upper channels and two Topping TP-60's for the 2 bass channels. They do a remarkable job actually.
I tried PP amps on bass but the chip amps control the cones better, cost less and use a fraction of the juice - what's not to like.
T-amps can get you a long way on efficient drivers. I used 3 for the upper channels in the beginning. The SET amps do sound more sweet / valvey if you are into that kind of thing though.

I am a bit more into speed slam and transparency I do not like a cold harsh sound but find when Digital is done right it can give me a lot of what I enjoy for not crazy money
Awaiting for Mini DSP to get back to me about how to integrate my bass amp if going done the DIY route with their amps
I found using active DSP on the bass took my bass forward I know a lot of people poo poo because its using pro gear but no bass overhang, punch and depth that would cost a fortune on conventional speakers

They are not DSP though and 4th order on all channels would not be my choice for a horn system but when I took my Laptop to test serving music instead of his LP's and used Jriver to make one correction of -3dB at 110Hz the system sounded pretty good indeed! I have another 5 way pal! who uses Jriver and a quality sound card to feed his amps - I've not heard it but he has heard my system a few times. I looked at miniDSP but all the plug-ins kinda put me off. Najda seemed like a fun thing to get into at the end of the beginning - I was too late to shape the spec much - like it's only 4 way... but I work around that nicely. I did get mine up and running among the first and found a few bugs - I also use it in a slightly different way to most who are 2/3 way. It will do FIR but I have not got into that - seems very complicated to me. I tried 8th order slopes on the bass - very precise and on off but prefer the slightly cuddlier 4th order overall. |

With my speakers my bass is coming in around 57 and using Butterworth 12db slopes. I added a bit of gain to the bass that gives me that punch i enjoy feeling but not with the sacrifice of any overhang of bass notes. Getting the balance how I liked it took time. I not measured the room but reckon the bass must go down to about 26

That's very good and will give great sub bass effect which I enjoy on various music - Yello, Bach, AC/DC or Lorde being a few examples out of so many:) Good fast deep bass is the underpinning of some music of course. If it's there we should have systems that can convey it.
