Eliminated my preamp with amazing results

much appreciate antirunge2. I will stop saying thanks (just think it) to not clog up the conversation.

As i said with the huge difference in price, design quality, needs etc there is no rule applicable to all case...

Removing a preamplifier or adding one CANNOT be a rule for all cases...

For me, i just receive new tubes for my low cost Douk preamplifier i coupled to my active speakers ( heavily modified) the difference before with low cost tube was evident for the better, it is now staggeringly better with these tubes...I will never return to self amplified speakers with no tube preamplification...As i will never use low cost active speakers with rear porthole without redesigning it for the best and the tweeter waveguide too .. 😁

In my case it was necessary to add a tube preamplifier ...

By the way my sound quality for the invested price amaze me so much it cannot be believed even by me listening to it ...😁

Acoustics, and electrical and mechanical workings controls embedded  devices are the key...

i pity anyone who pay more for not much better...

buy high-end gear yes if you can , but learn how to embed it seriously...If you miss optimizing your gear you will upgrade unnecessarily... Trust me on this...

😊

Am i deaf if i am wrong feeling no need to upgrade to a high end system ?

The truth is between a well optimized system at any price and a costlier one not optimized the difference if it exist is thinner than most people think ...Not worth the money in many case.... Then if you had just bought high end learn how to embed it ...

Could put in a transformer for volume control and diy.

I don't know if it matches your intentions, but if you need a switch with volume control, you could use a passive preamp (volume attenuator with input selector). Some high end brands are Goldpoint, Hattor, and Khozmo.

The RME ADI-FS DAC has a volume control. It is a top-notch digital implementation; I believe the claim that the sound quality is the same no matter how low the volume setting.

1. I turned my preamp volume to near maximum, then raised the DAC volume control to my desired listening level.
2. Noted the dB level with a simple sound meter app in an Android device.
3. Removed the pre-amp and raised the DAC volume to match the dB level.

In my case, I preferred the sound with the Van Alstine Transcendence RB 10 pre-amp.

Thanks for sharing this. I just picked up an RME ADI-2 DAC FS. A friend has a bunch of big $$$ gear and was raving about it... talked about it replacing his expensive preamps. I first put it in with my Ayre KX-5 Twenty preamp and thought "Holy Cow... that thing IS pretty good". He said I hadn’t really heard it until I put it direct to my Ayre VX-5 Twenty amp. Well, I am now... and... well... I’m not sure it’s as good. It’s certainly not a "revelation" such that it makes the Ayre KX-5 Twenty obviously obsolete / redundant. (Which is a clue to me). I am going to go back and forth, but I have a hunch the "stuff" / dynamics... whatever, that the Ayre KX-5 Twenty does, is maybe just worth having / keeping...and in the end maybe I prefer it. Notwithstanding that, the RME ADI-2 DAC FS is really friggin’ cool. It’s a special piece and I won’t be selling it, unless they come up with a better widget to replace it with. I have the AKM4493 version.

It’s also occurred to be to be very cautious about selling a good preamp. You never know what new toy is going to come down the pike that "I wish I’d kept that preamp" to use. I suspect I am always going to want to own a great preamp. If I'm not mistaken, I believe Ariel Brown at Ayre has referred to the preamp as being THE most important piece in the chain... 

I can attest to the use a really good preamp or don’t use one at all approach. I moved up to a Ayre Acoustics KX-5 Twenty preamp and it’s revealing everything I’d been missing before. And here’s the deal, as I’m just getting back into this hobby I haven’t even added a DAC yet, using a old Yamaha CDC-845 CD player feeding to the Ayre preamp then the preamp feeding to Phillips FA950 integrated amplifier with the volume left at the pegged position for it to temporarily act as an amplifer. One component at a time, rebuilt the Kappa 9’s and picked up a good preamp, next up some good amps, then a good DAC. I think the preamp is the most important component, it can easily be the most expensive component if you want a really good one. Controlling the volume is a huge challenge and only the best preamps can do it without losing anything in the signal. It’s why we always compensate by turning the volume up, it ’sounds’ better, but with a good preamp it’s very dynamic across the spectrum at the lower volume settings and that’s where it can be magical, you don’t need to blast it for it to sound good.
