My Final Amplifier Purchase - What Would You Buy?


I'm a lifelong audiophile/music lover and earlier this week, I had a life changing event. As a result, I am now in the position of purchasing what is almost certainly my last power amplifier.

To quickly explain, I was just notified that my entire department will be outsourced, effective September, following the completion of a transition. The buyout is not great, but they do extend my service time for an additional period, allowing me to begin receiving my full pension in September. So essentially I'll be okay financially, but certainly not enough to buy this level of audio gear down the road.

So, what this leads up to is that I was in the market to buy a quality used power amplifier (up to $4000.00 budget)to upgrade my system. I can still manage to do that, but clearly need to do it soon while the paychecks are still coming in. In the future, I simply won't have the financial means for a purchase like this.

Thankfully, the rest of my system is solid, and this should essentially complete things for the future. I'm very happy with the preamp, but I suppose that could "possibly" change one day, maybe to tubes,in a break even trade, but beyond that,if it even happens, the system should remain what it is.

Current system:

Meridian G02 Preamp
Meridian G08 cd player
Olive D4 Music Server
Silveline 17.5 speakers
Marantz SA8004 SACD player
Bryston BDA-1 DAC

and the power amplifier that I will be replacing:

Atma-Sphere S30 MK III.1

I truly love the S30, but a friend recently upset my satisfied audio world when he brought over his new Plinius SA-103 amp and that changed everything. Even more than the sound of that amplifier, which was superb, it became readily apparent that the Silverline 17.5's really only open up and fly when given that kind of power (100 wpc or more.) I also tested it further with a second amplifier and verified that the power is key to really getting the most out of the speakers.

I have long been an avowed tube lover, but there simply are not many options with the kind of power I am in need of, that fall within my budget. I've included a few as options below that put out 75wpc, because in my experience, thats roughly the equivalent of 100 wpc in solid state.

In a perfect world, I would just move up to the Atma-Sphere MA Series, but my budget is far insufficient. Also, a key factor is that I have a small room, even the M60's which (might) have enough power, would create a literally sweltering environment. Trust me on this, I've even talked to Ralph Karsten about it previously, and he agreed.

Based on that, some earlier suggestions here in the forum, and a massive amount of research, I have narrowed things down to a number of choices, which are, from my perspective, likely the best options. What I am truly in need of are any thoughts, expertise and experience you might have had, especially with multiple amplifiers on the list. I have not actually heard any of these. Also, if there are better options that I've missed, please mention them.

Lastly, remember that I would be buying used to maximize my options and value. Thanks in advance for any assistance in helping me choose my best path here. The help is greatly appreciated.

What I have identified as good possible options:

Parasound JC-1's

Pass X250.5

Pass XA 30.5

Jeff Rowland Model 6 Mono's -(I fear these only appear extremely rarely though, and given their age, may need servicing and new caps,etc. possibly putting them out of reach)

BAT VK-75

Modwright KWA 100SE

Primaluna Dialogue 7 Monoblocks

An old Threshold S series thats been refurbished? - These have always fascinated me, but would it last another 20 years?

Please consider the cayin 100, great sound, great value. Also, you are no audiophile if you will surrender to such a notion as a 'last' anything.
I will play along your pessimistic line. None of us may last for another twenty years. Get what you really want today.
You liked Plinius so it can be a very simple decision. Some older Rowlands have a cult following and for good reasons. With luck they will last for another fifty years.
Definetely MC2 audio (MC-1250 or MC-750) both much better than Parasound JC-1's & extremely cheap!
But if budget is no object than undoubtly Reyaudio or FM acoustics.

No matter which of the three brands you will take, your search will be over
Hi,
I just retired and bought my amps for life. I invested in CODA amps and preamp. CODA was formed by Doug Dale and a group of engineers who worked for Threshold along with Nelson Pass when it went under. Pass formed Pass Labs the rest formed CODA. Both companies use similar high quality circuits and design. I had both the Coda CP Preamp and the Pass XP 20 to evaluate. I would give a slight nod to the Pass I build quality but nothing sonically. Price Pass $9000, Coda $3500.
The CODA CSX amp has 25 watts class A and will not heat up your room at all. It runs cool to the touch even when pushed to the max. The Coda electronics have been found to be superior to the following amps and my system.
JC1 and the JC2
Krell Ksa 250
Krell mda 500
Levinson's 436
Pass xp 20
Levinson's 32 and 380s
Arc ref 3
Give it a listen. I don't think you'll be dissapointed.
Available at Coda direct sales or through Legacy Audio in Springfield.
The Pass XA30.5 is my choice, but the Modwright will operate a lot cooler and also sound nice. The Parasound monos are huge and get warm plus do you need that much power? The Pass X250.5 is good up to the 15 watt Class A rating, but then transitions to AB so that's why I like the XA30 better. Also only about 1/2 the people know the Pass XA30.5 will not clip above 30 watts, rather it transitions to AB over 30 watts, up to 120 watts, and then clips.

Good luck on your choice. Also, please keep us posted as there are a lot of members looking for good amps in your price range and your listening experience and research can help a lot.
