Amplifier upgrade


I have an Aragon 8008 bb (mk.2), and was wondering if I wanted to upgrade from that what might be recommended. (Bryston, Halo, Pass).  I currently have an Audio Research preamp, Cary source, and Sonus Faber speakers.

Thank you in advance.

Thank you.  I think the 8008 bb is a still a very good amp as you said.  I would agree it's a bit warm and a bit slow, but has allot of drive.  A Pass 250.8 would be a big step up I would think.  It uses a Mosfet output stage, but I assume still would have serious drive and bottom end.  Have you heard the A21 in comparison to the 8008?


Yes, the 8008bb definitely has a lot of drive -- it’s a high current amp and has no problem driving a wide variety of speakers. I have not directly heard the Parasound, but I have heard many on this forum describe the characteristics. I have moved on to Emotiva monoblock amps myself, but that’s where I’m at. The stock Emotiva’s are very fast and nice, but just a tinch on the cold side -- upgrading the fuse to an Isoclean really helped and now it’s like a fast/engaging version of 8008. I would say the Emotiva amps (when fuse modified) are worth much more then what you spend on them, but there is definitely a perception that they are "cheaper" and not as good. I run 6 individual monoblocks in a home theater system, and it would be insane to buy Parasound/Pass monoblocks for this many channels, so Emotiva is what I ended up with. In reality, I suspect the Parasound Halo amps will sound sweeter than the Emotiva amps -- the Pass Labs "Class AB" amps are probably the superior amps all around. Please read the following thread on a huge amount of individual amp descriptions.

I recommended the Parasound A21 as a stereo amp upgrade from your 8008bb stereo (dual-mono), but JC1 monoblocks would be better (and much more expensive, lol). Based on the above thread, the Pass 250.5 would be better than JC1’s anyways.

Thank you for the detail.  I have not heard the Emotiva amps as of yet.  I think if I was going the Halo route I would go JC 1's for sure.  The Pass 250.8 seems to be a great amp from I have heard, and a step up from everything we are talking about.  Any experience with the D'Agostino Classic Stereo Amp for 12k?    

The Emotiva amps are an excellent choice if your budget is limited. It’s my opinion that you’d have to spend significantly more to get something better. I’m running XPR-1 amps for the main channels and it’s hard to bet something that has 1000W, 240,000uf power supply, 36 output transistors for that price. I’ve looked and the best I can come up with is a Bryston 28BSST, but at 4-6 times the price and the fact that I don’t really like the Bryston signature, it’s just not worth it to me. At this point, I have over $8k in amps.

I think you’re already in the range where you will get something better than Emotiva anyways. That D’Agostino is interesting. Definitely a beast:

If you’re already looking in this price range, Reno Hi Fi has a pair of used (demo) X-260.8 monoblocks for $10k. If I was looking in this price range, I might be leaning towards these Pass monoblocks. Monoblocks are -generally- fully balanced/differential whereas stereo amps are -generally- single ended.. The monoblocks will have completely separate power supplies which will probably help drastically with imaging (D’Agostino has separate power supplies, but with a shared transformer). Also, having two monoblocks there in your room can look more impressive than a single stereo amp (though the Classic Stereo is definitely huge -- but there is some empty space inside the amp case). This is completely an asthetic reason, though. All that with the penchant that Pass has incredible bass slam and overall excellent sound quality would tend to make me choose the Pass monoblocks. Please note that I’m making an educated guess based on what I’m reading on these amps and it could very well be that the D’Agostino is the superior sounding amplifier.

both the Pass X250.5 and X250.8 would be a big step up from the the A21 or the 8008.  The 250.8 is also worth the cost over the 250.5
