4425 has offered a good suggestion in the used D'Agostino S200, but ricred1 also has brought up the Rowland 625 s2 which should be close to your budget and is a superlative amplifier. Can't go wrong with Pass either but I think the D'Agostino and Rowland are in another league.
Amplifier Upgrade Decision
Hello,
I need some help/feedback with regards to upgrading my power amplifier for 2 channel music. My current set up includes following components
1. Source (Digital)- Oppo BDP-95
2. Source (Analog)- Clearaudio Concept Turntable
3. Pre-Amplifier- Parasound Halo JC-2
4. Pre-Amplifier- Parasound Halo P-7 (using the phono interface for playing the turntable)
5. Power Amplifier- Parasound Halo A-21
6. Front Speakers- Aerial Model-7T
7. Power Cable- Nordost Heimdall 2 and Red Dawn 2
8. Interconnect Cable- Nordost Frey 2, Heimdall 2 and Red Dawn 2
9. Speaker Cable- Nordost Red Dawn 2
10. Wall Receptacle- Furutech GTX-D NCF(R)
11. 2 Dedicated 20 Amp (10 AWG) circuits feeding the entire system
12. GIK Room Acoustics Bass traps/Diffusors
13. Room size- 16’ X 12’
This set up sounds good but I wanted to take it to the next level and wanted to upgrade my amplifier to a better 2 Channel amplifier or a set of mono-blocks. I love Class A/AB sound and would like to stick to this technology. My choices, not in any particular order, are
1. Upgrade to a Plinius SA 103 (125 W pure Class A per channel) and use it as a 2 channel amplifier
2. Upgrade to a set of Class-A mono-blocks. My choices, not in any particular order, are
a. Parasound Halo JC-1
b. Pass Labs XA-60.8
My budget is around 10-12K.
I know everything is system dependent but I would love to hear your opinion on these amplifiers before starting on product evaluation.
I am also not sure if my mono-block amplifier choices would provide significant value add from a sound perspective over the Plinius or any other good quality 2 channel amplifier at this price point. So I would love to hear your feedback on this point as well.

The JC1s seem the default option. The advantages of monoblocks are (1) forced separation of the two channels - not a biggie - and in any event you do get 'dual mono' power amps; (2) The separate chassis are very useful for heatsinking. It can mean a particular design can be biased higher. (3) Speaker wiring can be shorter. This is beneficial, and said to more important than the corresponding interconnect cables. I'm not too sure about this latter point but very long unshielded interconnects can be an issue. I was in a similar situation to you recently. I ended up getting a Pass X150.8. Fab sound quality but it runs hot, and takes a long time to warm up (I know that sounds like a contradiction. Others on my short-list were David Belles http://www.powermodules.com/about.html and Pureaudio who have a US presence. http://www.pureaudio.co.nz/ Plinius is great but Pureaudio can only be better. I guess that is how I would have gone but the Pass came up at an auction so I had to make a quick decision. |
The Pass XA-60.8 would be too weak for your speakers. The Plinius is a good choice. The other better choices that I would look into are: 1. A pair of Benchmark AHB2 in mono configuration. Save money for something else while getting a sound you may never want to change. 2. Gryphon Diablo 300 - performance and sound near the very top high end 3. Hegel H30 - Sound, full control and power - upgrade to monos later My personal discipline concerning speaker/amp matching, besides having all the obvious sound qualities, is to get amps that are much higher in power than recommended by speakers (one must discern between ClassA and AB of course). I believe that audiophiles dont take this enough into account when choosing amps. Many many amps out there have a real good sound, but control of the speakers is paramount if you want to have real dynamics and continued separation of instruments on complicated pieces at fair volume levels. |
@hddg- I completely agree with the power criteria and it's importance that you have brought up... Initially I thought 60W would be too less for driving the Aerials but Pass Labs product team confirmed that I would be fine with it in my relatively small room 16' X 12' room, specially with Class A power. I am trying to find out how much Class A power I need in my room to drive the Aerials w/o loosing dynamics and bass. Is there a way to find that out before buying the amplifier? Thanks |
