Do I really need a preamp with dac with volume control help

I was putting together a system in a second room and placed order fo Audio Hungary integrated but found out they had no repair center in U.S. and canceled order.

So I ended up buying a Don Sachs with the intention of buying the matching preamp. Im running the RME adi-2 v2 with Teddy Pardo power supply directly into amp. I’m not using phono or CD in this room.

It really sounds very good. Big full detailed with no lack of gain. Not at all like I’m missing anything at least I think so. Then at times I second guess this, I just don’t know.

Long ago I had a PS Audio RAM modded amp with PS audio preamp with outboard power supply out of curiosity I pulled the preamp out of the system ran balanced to phono pre, it had a volume control and everything opened up and sounded much better. Preamp and PSU went in the closet. 

I don’t want to make same mistake I did in the past and spend a bunch of money on a preamp that may not improve things. It could also make things sound worse like my experience with the PS Audio. 

Can someone advise me why I am experiencing this. Should I buy a preamp, am I missing out without having one, I know I can buy preamp and see and if it doesn’t work and then I can sell it but what a pain and expense, thanks for any insight.

This is also something that I have wondered about.  I use an MSB Discrete DAC direct to my Pass Labs 250.8 and it sounds great.  Some have told me that putting a preamp in will improve the sound.  Others, like Vince Garbo at MSB, say no.  To me, it seems as if most designs try to minimize the amount of “stuff” in the signal path, i.e., the less in the signal path, the better the sound.  So it is counterintuitive to me that putting all of the wiring and electronics of a preamp into the signal path between the DAC and the amp would actually improve the sound.  How does that work, logically?

@paulcreed, There is no right or wrong answer to your direct to power amp, or preamp question. The answer is it depends on the equipment used and how it sounds to you. AND, if you ask everyone on Audiogon, you will get many different answers.

The only way to get the correct answer for you, and YOUR equipment, is to test and listen.

It depends on the number of bits available from the DAC, the output voltage of the DAC, the input sensitivity of the amp, the capacitance of the interconnects between them, and the impedance compatibility of it all.

Technically you might not NEED a preamp but I have never seen a top performing system that didn't have a quality preamp.

Given your enjoying the system and it is working well for you, I would not bother. For high end critical systems not having a preamp seldom is a satisfying and fully fleshed out sound. But since it is a secondary system, I would leave it there. 
 

Leaves more money for your main system long termed.
